Getting A Shirt Design Onto Roblox From Your Phone
Roblox doesn't have a native shirt editor in their mobile app. You have to do the design work outside the app and upload the finished file through the website. That's the first thing to understand, because a lot of people waste time looking for a button that doesn't exist. The actual process takes about twenty minutes if you already know what you're doing, and maybe forty-five minutes the first time through. You need three things before you start: your Roblox account logged into a browser with upload permissions enabled, an image editing app on your phone, and a flat template of the Roblox shirt UV map. I use Procreate on my iPad or the free Paint app on Android, depending on what device is in my hand at the time. The template is a rectangular image where the torso, sleeves, and legs are laid out flat. You paint on it, then upload the result as a .PNG file.
How To Make A Roblox Shirt On Mobile
Search for "Roblox shirt template PNG" and grab a blank one. The standard dimensions are 512 by 512 pixels. Open it in your editing app. Build your design on top of it, keeping the arms and legs areas separate since they wrap around the character model differently. When you're done, export it as a PNG with transparency where needed. Log into the Roblox website on your phone browser and navigate to Create, then Shirts. Click Upload, select your file, fill in the name and description fields, and confirm. It processes for a few seconds and the shirt is live. I know that sounds too simple, and it usually is. The problems come later. The UV mapping in Roblox is inconsistent between body types. The standard R6 avatar and the R15 avatar stretch the shirt template differently. If you design something with precise alignment, like a collared shirt or a logo that needs to sit centered on the chest, it will look squished or misaligned on R15 bodies. The fix is to test your design on both avatar types before you publish it. I discovered this the hard way when I spent an hour designing a striped polo shirt only to realize the stripes were angled wrong on taller avatars. My workaround was to create two separate versions and link them in the description so buyers know which one fits their model.
There are some constraints you need to work around. The file has to be under four megabytes. PNG is the only accepted format for uploads. The canvas must be exactly 512 by 512 pixels. If you resize it even slightly wrong in your editing app, Roblox will reject the upload silently. I've had shirts bounce back with no error message at all, just a red banner that said the image failed validation. Turned out I was using 500 by 500 instead of 512 by 512 because the template I downloaded was slightly off. Check the pixel dimensions manually every single time before you export. Another thing nobody tells you: the shirt layer renders behind the accessory layers. If your design includes shoulder pads, belts, or anything that should appear on top of the fabric, it won't show up unless you add it as a separate accessory. I learned this when a user complained that the epaulets on their military-style shirt weren't visible. The design was perfect. The accessory system just overlaid it differently than expected. If you want a smoother workflow than building everything from scratch each time, there are online tools like the Roblox Shirt Designer web app and various third-party canvas builders that let you compose designs with pre-placed panels. They save time on the template alignment, but they don't replace the actual image editing step. You still need to produce the final PNG yourself.

The biggest bottleneck is the preview process. You can't see how your shirt looks in real time while you're editing on mobile. You have to repeatedly upload, test in-game, adjust, and re-upload. Each upload cycle takes roughly three to five minutes including the processing wait. A complicated design might go through ten cycles. That's thirty to fifty minutes of trial and error. I usually do the bulk of my editing on a desktop when possible and only switch to mobile for the final upload and quick tweaks. If you're making shirts for a group or a brand, consider using a shared template file that everyone on your team edits from. This keeps the UV layout consistent across multiple designs. I've seen groups fall apart because three designers used slightly different template versions and the clothing line looked mismatched in-game. The whole system works, but it's not streamlined. Roblox has had requests for a built-in mobile shirt editor for years. It hasn't happened. If you're committed to mobile-only creation, the best approach is to pick one editing app you're comfortable with, save a stock template in your phone's cloud storage, and build a small set of reusable design elements like logos and pattern pieces that you can drop into new projects quickly.
