If you’ve ever stared at a pack of masks and wondered, “Which mask size is for me?” you are not alone. Finding a mask that fits your face is a deeply personal challenge. Even if a specific model gets rave reviews and fits many people, it doesn’t guarantee it will fit your unique face shape. We often compare it to buying a pair of shoes—you can’t really tell if they’re “the one” until you actually put them on.
However, there is a massive difference between shoes and masks. You can walk into a store and try on ten different pairs of sneakers. But with masks, for obvious hygiene reasons, no one will let you try a new one until you have purchased it. Once you open that sealed pack, the product is yours to keep—for better or worse.
How can I determine whether the mask is my size without risking money on a product that might not seal properly?
Some companies have built a business model around this problem by selling “sampler packs.” These sets contain a few different models, allowing you to test them one by one. The idea is you pay for the sampler now to avoid buying the wrong box later. The catch? Whether you find a perfect match or not, you still have to pay for the privilege of trying.
At Totobobo, we decided to do things differently. We didn’t want you to have to pay just to find out if our mask might work for you. We believe that mask fitting your face shouldn’t be a gamble.
The Free Solution: The Totobobo Simulator
We created a better, fairer solution: the Totobobo Simulator.
This is a free, downloadable paper dummy of our actual mask. It’s a full-size template that’s easy to print and assemble. While it doesn’t contain a filter and won’t provide respiratory protection, it serves one crucial purpose: it allows you to test, for free, whether the physical dimensions of the Totobobo mask will fit your face.
Experiment Without the Risk: Finding Your Size
The simulator isn’t just a static model. It’s a tool for experimentation—perfect for answering “how do I make it fit my face?” before you even place an order.
One of the key features of the real Totobobo mask is that it can be trimmed to achieve a perfect, custom fit for smaller faces . The simulator lets you experience this process without any risk.
- If it is too big, simply trim the paper simulator’s edges as you would cut the real mask.
- If you cut it too small: No problem—just print another one and start over!
It’s the perfect way to practice and build confidence.
We know this is a common concern. We often hear: “How do I know it will fit better after cutting the mask? I’m worried about cutting too much and ruining it.”
With the Totobobo Simulator, that worry is a thing of the past. You can download it, print as many copies as you need, and experiment with different trims until you find the perfect size.
How to Use Your Simulator for the Perfect Fit
- Assemble: After three simple steps of cutting and folding, you have your very own simulator!
- Test: Hold it up to your face. This is the fun part. How does it feel? Is it too big?
- Trim: The position of the trim lines on the simulator is directly comparable to the real thing. You can follow them to achieve our standard sizes (M, S, XS) or any custom size in between .



A Note on Reality vs. Simulation
It’s important to remember that the simulator is not the real mask. While it is an excellent tool for judging size and basic geometry, it has its limits. The most significant difference is in the nose bridge area. The paper simulator is flat, whereas the real Totobobo mask features a curved 3D profile that contours to the human face for a better, more comfortable seal.
Think of the simulator as the perfect first step. It ensures you have the right size before you ever open a sealed package. From there, you can order the real mask with total confidence, knowing that the only thing left is to experience the superior comfort and protection of the actual 3D design.
