Paper prototyping is alive and well. Read on for brilliant examples, resources and how to get started
How does your handwriting compare to a decade ago? Has it worsened, improved, or is it just different? Let’s face it. Using paper is less common in the digital age. No one does their accounts in actual books anymore and most written communication is done online and through messaging apps.

But what about prototyping? While it’s not as common nowadays, paper prototyping still serves a business purpose in the design world, other than making sure your sketching technique doesn’t get rusty.
This post will discuss the benefits of using a paper prototype but will also explain why it doesn’t replace the work done in your prototyping tool. In addition to that, we’ll walk you through how to make one as well as some free resources to get you started.
Paper prototyping apps and websites is a method some design teams use to begin conceptualizing a new product or feature. However, it goes a little further than that. It also helps to demonstrate the user flow and functionality that your future design will have in the very early stages of ideation. It’s a way of obtaining client and stakeholder buy-in before you start to work on your high-fidelity prototype.
![Paper prototyping - definition](https://assets.justinmind.com/wp-content/uploads/2021/01/paper-prototyping-definition.png)
Designers like Jake Knapp have a slightly pessimistic view of paper prototyping. They reason that it’s an outdated technique whose days are numbered. However, as Jake puts it himself, it’s not entirely useless, but he also maintains that paper prototypes “should never leave the conference room”.
In other words, you should never test them on your users because they are not realistic and detailed enough. Therefore, they could never produce a realistic reaction from your users and is a waste of a tester’s time and resources. That was back in 2014. A lot has changed since then and in the field of UX design. Agile and Lean UX workflows have come a long way.
The idea of constant iteration is becoming the regular mantra of design teams the world over. So we at Justinmind would be inclined to disagree that you can’t test paper prototypes. Ideally, you should test your product throughout the design process, at all phases and fidelities. Any idea you have becomes validated all the more when you test it out on your target users. They take priority over stakeholder’s opinions. Afterall, your users determine the real success of your product.
Why take your time to draw lots of screens composed of elements and text, then immediately move on to a high fidelity prototype, when you could first run it by your users? You may find your hi-fi prototype will look quite different if you test your paper prototype than if you didn’t.
No matter what digital mediums you have available to you, there’s nothing like paper and ink to get ideas flowing. Paper prototyping is a great way of quickly weeding out the bad ideas and learning about the right design path to take with your digital prototype.
![Paper prototyping - ideation and brainstorming](https://assets.justinmind.com/wp-content/uploads/2021/01/paper-prototyping-ideation-brainstorming.png)
In a way, paper prototyping is to high fidelity prototyping what high fidelity prototyping is to development – less reworks, and more time saved. Sometimes, when designers build weighty Photoshop and Sketch files leading to detailed prototypes with high degrees of interaction, it can be difficult to go back and fix small errors. Paper prototypes are a faster way to avoid these errors occurring in the advanced stages of design.

The other benefit to paper prototyping is that pretty much anyone can make rough sketches with no need to have knowledge of design tools. It’s a great way for stakeholders, clients, developers, product managers and other non-creatives to demonstrate their ideas.
That also brings us on to the next reason why paper prototyping is good: it’s a fun way to forget roles for a moment and bring the team together.
Paper prototyping can also be a great team-building activity in disguise because it inspires the team to get creative. Sketching, cutting out and coloring are a way to get people to chill out from the screens for a while. It also makes them feel like they have more of a voice in the matter and that way, everyone feels listened to.
![Benefits of paper prototyping](https://assets.justinmind.com/wp-content/uploads/2021/01/paper-prototyping-benefits.png)
The other obvious benefit of paper prototyping is that they’re notoriously low cost. All you need to do is pay for the stationary and you’re laughing out loud. In addition to that, they can save a designer’s time by letting them quickly scribble out an idea and get it validated by stakeholders before moving on to higher-fidelity prototypes. At the end of the day, the longer a designer spends on a project, the costlier it will be.
Usually it’s easier to gain honest user feedback at the primitive paper prototyping stage. This is because they understand what you’re doing, that you’re just trying ideas out and the sky’s the limit (at least from their point of view).
So when it comes down to it, that alone is a pretty good reason. However, we could also make the point that when a user sees your prototype in more detail, they may think there’s less room for change because it looks more complete. Therefore, may be more a loathe to make suggestions or to provide feedback.
However, they’ll be more likely to voice their feedback and display their true reactions if it’s just on paper. There’s something about a paper prototype that seems less serious. And yes, that’s a good thing psychologically!
Paper prototypes bring many benefits to product design. However, they also have some drawbacks, meaning they’re still not sufficient enough to replace digital prototypes. Here’s why:
![Cons of paper prototyping](https://assets.justinmind.com/wp-content/uploads/2021/01/paper-prototyping-drawbacks-cons.png)
The paper prototypes lack important details such as the following:
- Microinteractions
- Mobile gestures
- Interactions
- Branding
- Images and advanced graphic design
- Real content
- Data visualization
All of the above aspects can have a huge impact on your users. Therefore, it’s vitally important not to skip these and to test them out before you code your final product. Paper prototypes fall short in all these areas.
It’s also harder to implement branding (apart from drawing the logo) at this stage than at the high fidelity prototype stage. When it comes to stakeholder buy-in, as well as knowing what effect a certain range of colors used from the branding palette will affect the users in a way that positively cements the brand, this becomes an important detail.
The other problem with lack of detail and that you must also bear in mind is that you are also limited when it comes to accessibility testing.
At this stage, you won’t be able to test whether your visually impaired users or those who are hard of hearing would be able to successfully navigate through your product by themselves. It will also exclude users who have impaired motor function as you won’t be able to test out gestures or mouse movements or use screen magnification software.
The other disadvantage comes in the fact that with paper prototyping, you can forget remote testing or testing with large pools of recipients.
![Paper prototyping - only moderated testing works](https://assets.justinmind.com/wp-content/uploads/2021/01/paper-prototyping-moderated-testing.png)
With paper prototyping, you’ll need to be testing solely with small groups, for obvious reasons. Sure, you could print off many copies and, if you have a large enough team, test groups simultaneously with different moderators. However, this can lead to chaos and can also skew the results if certain moderators deviate from the script.
Lastly, it’s only possible to do moderated testing, as paper prototypes are manual prototypes. It’s a very manual form of testing. You’ll need to have someone to act as the computer (more on that below) and it will obviously need more explaining from the moderator.
Paper prototyping also falls short when it comes to demonstrating activity. You can demonstrate the basic functionality your product will have and the basic user flow, but that’s pretty much it. Microinteractions and animations will be off limits at this stage, as will testing out hand gestures and mouse interactions.
Aside from the fact that paper prototyping can quickly get out of hand when it comes to lots of sheets of paper that you have to keep track of during testing, it’s far less environmentally friendly than its digital equivalents. And since many companies are moving towards a more paperless environment, it might be more difficult to convince them of the need for all that paper.

To make a paper prototype, you’ll need to make sure you have the right materials at hand. First, you’ll need to decide on whether it’s going to be for a brainstorming session between colleagues or for a user testing session. If you’re planning to use your paper prototype for a user testing session, it will probably need to be a little bit more refined.
Depending on the detail your paper prototype will have, you’ll need the following:
Sorry for the Captain Obvious on this one. Any paper works, but for best results, use graph paper, dot paper or sketching paper. Below, we’ve provided a list of resources to help you source these for free.
Drawing out new screens, phone, tablet or computer outlines can start to get old and frustrating pretty fast. Instead, draw out one screen template. Then photocopy, or scan and print it out. Or, just use one of the free template outlines we’ve included below!
![Paper prototyping - templates are useful and save time](https://assets.justinmind.com/wp-content/uploads/2021/01/paper-prototyping-templates-cutouts.png)
Consider the possibility of using different colors in your paper prototype. Avoid using pencils, as the lines don’t contrast as well. Pencil sketches can also end up messy. Pen or marker sketches are tidier because they encourage more deliberation and precision.
Using a ruler can help you quickly and easily draw lines, while also helping you to roughly measure line length and element spacing. While a ruler is optional, it can help speed up the process by allowing you to draw straight lines quicker.
![Paper prototyping - accessories and equipment](https://assets.justinmind.com/wp-content/uploads/2021/01/paper-prototyping-accesories-equipment.png)
These are also optional but extremely useful. Stencils can help you to quickly and consistently trace out commonly used icons. There are also some available that help you to draw out typical iOS and Android icons and elements. Check out our resources below for more information on that.
![Paper prototyping - stencils are helpful](https://assets.justinmind.com/wp-content/uploads/2021/01/paper-prototyping-stencils.png)

Why scissors? They’re great for cut outs. Perhaps you want to overlay elements or move elements around the paper prototype’s screen. You may also need it to cut out new template screens to attach to cardboard or magnets.
Take a breather, relax the shoulders and then put pen to paper! Get a few quick doodles out of the way first.
Draw your ideas out fast and don’t worry about the details. Just make sure it’s not too cluttered and that other people will be able to understand it. Remember, what you’re trying to get across to people is your idea or concept, not admiration for the lovely UI you’ve just drawn. Draw quick and deliberate lines and make circular shapes once or twice in the air before you put pen to paper.
Before drawing, take into account the size of the different texts you’ll write onto the paper prototype screen. Make sure there’s a clear difference in size between header and body texts, even button texts and inline instruction texts.
Never write in Lorem Ipsum! Everything on your paper prototype should be useful, otherwise you shouldn’t bother including it.

If your paper prototype is for office use only, make sure to include technical annotations if it’s for developers or annotations for your decisions and functionality if it’s for team members or clients. If it’s for user testing, you can leave the annotations out or write them on another, duplicate screen by printing it out again.
Lastly, when it comes to the matter of buy-in, and even though we’re not really focusing on detail and branding at this stage, drawing your client’s logo well always goes the extra mile in helping convince them of your design argument.
Best of all, go in prepared. Read Caroline Schneider’s book Paper Prototyping: The Fast and Easy Way to Design and Refine User Interfaces. Caroline is a usability engineer and serial paper prototyper. In the book she talks about everything from simulating different UI elements and interactions to how to schedule testing activities.
At Justinmind, we recommend you have one person in charge of this job while someone else acts as moderator. The reason for this is that the human computer needs to be very attentive to what actions the user takes and how to interact accordingly, while the moderator needs to be concentrating very carefully on the user’s responses and behavior.
Doing these two tasks together is not impossible, but can seem easier than it is in practice. If you have the resources to be able to separate the tasks between two people, the better. For example, the moderator could set the video to record and begin the session, while the human computer is ready for the user to start interacting with the paper prototype.
Think about any elements that could move around a screen in the paper prototype and make any appropriate cutouts. Think about drag and drop actions.
![How to make paper prototypes interactive](https://assets.justinmind.com/wp-content/uploads/2021/01/make-paper-prototypes-interactive.png)
In addition to this, think about having the human computer color in any radio buttons the user selects with a pencil and using an eraser to deselect them. The human computer can also color in button state changes with a crayon, coloring pencil or marker. Anything you can do to make the experience more realistic will help as it will make the experience more meaningful for the user.
Most importantly, you should always rehearse the session vigorously with your human computer and any other moderators that are going to be present during the session. The length of time you spend preparing for the test will depend on the length of the paper prototype and how long the tasks are that you want the users to complete.
Rehearse which links lead to which screens, as well as how the human computer interacts with the user as they make their decisions. The moderator should rehearse the questions they’ll ask the user during each step and possible variations that could occur. At this point they could also consider what types of open-ended questions they could ask in order to elicit the most profound responses.
![How to carry out paper prototyping testing sessions](https://assets.justinmind.com/wp-content/uploads/2021/01/paper-prototyping-testing-sessions.png)
As a basic rule of thumb, we at Justinmind would advise not making the testing session so long. Don’t test out more than one or two features in a given session, and try not to have the session go over an hour. If it does, be sure to give your users a break in between sessions.
Print out or photocopy more copies of the prototype than you need. Imagine there’s a mistake made or more testees show up than you expected. It’s always handy to have a backup! As a general rule of thumb, NNG suggests only testing with five users in a group anyway.
As is the case with most user testing sessions, it always helps to offer the users some kind of incentive beforehand. It might be a free coffee, or if you’re working for a company that already exists, it might be a free coupon for a service.
When it comes to any user testing session, whether with digital testing or paper prototyping, recording the results is key. With moderated testing, having someone recording the event is crucial. Just make sure you inform the users that they’re going to be recorded and obtain their permission!

In this paper prototyping example for an app called DoIt, we can see how cut outs can be creatively used to put together different screens by mixing and matching elements.
![Paper prototyping with cutouts](https://assets.justinmind.com/wp-content/uploads/2021/01/paper-prototyping-cutouts.png)
It’s also a useful way of paper prototyping forms, as the user can write in their username or password on a small rectangular cut out which can then be placed into the field by the user, the human computer, or the moderator.
What we like about this multi-channel paper prototype example is the creativity. It uses a combination of cut outs and color to make the prototype more meaningful. It also simultaneously demonstrates how a multi-channel use of the app might work with smartphone and smartwatch cut outs.
![Multi-channel paper prototypes](https://assets.justinmind.com/wp-content/uploads/2021/01/paper-prototyping-multi-channel.png)

We also dig the way they use one color – pink – to differentiate between interactive elements and text.
To give you an example of a paper prototype with annotations that might typically be reserved for office use, this one from Alexander Skogberg shows how to cater to your audience.
![Paper prototyping with annotations for developers](https://assets.justinmind.com/wp-content/uploads/2021/01/paper-prototyping-developers.png)
Image source: Alexander Skogberg
In this realistic and functional sketch, simple and clear technical annotations show that the idea is to convey the functionality behind the app idea to the developers early on in the design project. That way, it’s possible to know whether it’s worth turning it into a high fidelity prototype.
This screen flow paper prototype example highlights (pardon the pun) the use that a bit of color (without going over the top) can have in your prototype. In this case, the blue highlighter indicates the buttons or elements that are clickable or the flows to be tested in this prototype.
![Paper prototyping - depicting user flows](https://assets.justinmind.com/wp-content/uploads/2021/01/paper-prototyping-user-flow.png)

In the third screen, we can see that comedy has been highlighted to indicate the flow that the user selected.
This example shows just how creative you can get with your paper prototypes, as an iron iPhone mold with an empty screen is simply placed over the different UI screens sketched out on paper.
![Paper prototyping with iPhone molds](https://assets.justinmind.com/wp-content/uploads/2021/01/paper-prototyping-iphone-mold.png)
In this way, a user can navigate through a screen flow for mobile apps without having to use multiple sheets of paper for each screen. However, we’d advocate using real text here in place of the scribbles.

The template is also available in vertical or horizontal views.
Paper prototyping can be a useful part of the design process. But we must really emphasize the “part” it plays. It doesn’t, at the end of the day, replace digital prototypes. Instead, it can be used at the very start to guide your design direction.
When you have your paper prototyping session, be sure to include all stakeholders, i.e. the developers, product managers and even clients. Sometimes it’s easier to draw something than to explain it.
Once you have your paper prototype defined, go ahead and test it on a handful of users. The feedback you get from your paper prototype will be enough to inform the direction you’ll take with your high fidelity prototype.
