How to Test a Roblox Shirt Before You Upload It
Read the 18-face report as a checklist, retest the source, and confirm the avatar preview separately.
01
What does the Roblox shirt tester check?
The free Roblox shirt tester: strictly check 585×559 PNG or JPEG metadata and report coverage plus transparent boundary pixels for all 18 mapped faces.
- Choose an exact 585×559 classic-shirt PNG or JPEG and review the strict dimension and MIME checks.
- Inspect R6 or R15 orthographic views from the front, back, left, right, or both, with optional preview-only guides.
- Review exact coverage and transparent boundary-pixel counts for each of the 18 UV faces, then correct the source image as needed.
02
What does the 18-face report contain?
Each face lists its exact pixel coverage and transparent boundary-pixel count; the tool does not replace these measurements with a heuristic score.
03
Does passing the checks guarantee Roblox acceptance?
No. The checks cover only the local file metadata and pixels; they do not evaluate Roblox policy, moderation, or final rendering.
