EDITOR TEST · OCTOBER 3, 2026
Can You Turn a Roblox Shirt Template into a T-Shirt?
Switching this editor from Classic Shirt to Classic T-Shirt changes the PNG to 512 × 512, but it does not turn sleeve and back artwork into a front-only graphic. In our three-mark export test, sleeve and back marks stayed in the T-Shirt PNG outside the editor's front guide. Choose T-Shirt before placing art, or start a fresh T-Shirt canvas and import only the graphic you want on the chest.
This describes the current Avatar Shirt Maker editor. Roblox defines Classic T-Shirts as square front-torso images and Classic Shirts as mapped torso-and-arm images; neither format is automatically converted by changing a button in this editor.
Why the garment choice matters
Roblox's classic clothing guide treats a T-Shirt, Shirt, and Pants as separate asset types with different image layouts. A Classic T-Shirt is a square image shown on a blocky character's front torso; a Shirt wraps around the torso and arms. Roblox lists 512 × 512 as an example square T-Shirt size and provides a mapped template for Shirts.
Our editor changes canvas dimensions when you select a different type. That size change is real, but it is only a pixel resize: it cannot decide which parts of your Shirt design should become a chest graphic.
Our three-mark switch test
We created an original transparent 585 × 559 PNG with one colored 32 × 32 square in each Shirt area: green on a sleeve, red on the front torso, and blue on the back torso. In headless Chrome, we imported it through Choose image, clicked Download PNG, switched to Classic T-Shirt, and clicked Download PNG again. We decoded both downloaded blobs and measured the colored pixel bounds.
| Mark | Shirt export, 585 × 559 | T-Shirt export, 512 × 512 |
|---|---|---|
| Green sleeve | x 12–43 | x 11–37, outside front guide |
| Red front | x 176–207 | x 154–181, inside front guide |
| Blue back | x 440–471 | x 385–412, outside front guide |
Where the marks landed in the square export
The dashed region represents this editor's x = 128–384 front-placement guide. It is an editing aid, not a crop.
The T-Shirt export retained all three marks. Its green mark occupied 729 detected pixels; red and blue occupied 756 each. Those counts are lower than the 1,024 pixels per square in the Shirt export because the image was reduced. Switching back to Shirt restored the same measured mark bounds in this test. The editor also disabled Undo immediately after the template switch, so saving a copy before changing type is sensible.
What the test proves: a size-correct T-Shirt PNG can still contain Shirt panel artwork outside the intended front graphic. We measured browser exports; we did not upload this test image or verify its appearance on a Roblox Studio rig.
A safer way to reuse your design
- Decide what should appear on the avatar. For only a chest graphic, pick Classic T-Shirt. For a design that covers sleeves and the torso, pick Classic Shirt.
- Save the Shirt version first. Download its PNG before switching. This preserves a usable copy even if you later rearrange the artwork.
- Clear or start fresh for T-Shirt. Select Classic T-Shirt, remove old Shirt artwork, and import the logo or chest graphic by itself. Do not rely on the former torso-front panel to be extracted automatically.
- Place the new graphic inside the front guide. Check that no sleeve, back, or guide marks appear in the actual Download PNG file. The guide is visible while editing but excluded from export.
- Check the saved file and test in Studio. This editor's T-Shirt output is 512 × 512. Roblox says to use a ShirtGraphic object and its Graphic property for a T-Shirt on a Block Avatar rig; use Shirt and ShirtTemplate for a Shirt.
If you switched accidentally and have not done further work, switching back to Shirt returned our three marks to their original measured bounds. Treat that as a recovery option for this specific editor behavior, then inspect your own design carefully; text, strokes, and imported images can have different edges than our test squares.
Quick decision table
| You want to make… | Start with… | Check before export |
|---|---|---|
| A logo only on the chest | Classic T-Shirt | The graphic is centered in the square file; there is no leftover sleeve/back art. |
| A garment with designed sleeves | Classic Shirt | Front, back, and arms use the mapped Shirt regions. |
| Both versions from one concept | Two separate exports | Build the T-Shirt from the isolated graphic, not the full Shirt PNG. |
