ORIGINAL PIXEL AUDIT · NOVEMBER 10, 2026
Roblox Shirt Template Letter O: Stroke Width by Row
In this roblox shirt template preview test, a normal red O had 15–17 pixels of combined left and right stroke at its center row; the bold O had 24–24. Across three sampled rows of each saved 64-pixel preview, the combined stroke changed by 1–2 pixels for normal and 1–3 for bold. These are image measurements, not a readability or Studio rendering test.
What changes above and below the center?
We revisited 12 saved previews from the same exported Shirt design: six normal O and six bold O. For each preview, we added the left and right red-stroke widths on rows 28, 32, and 36. This produces 36 row totals. The table reports the minimum and maximum across six preview placements in each group.
| Preview row | Normal: two strokes together | Bold: two strokes together |
|---|---|---|
| 28, upper sampled row | 16–16 px | 22–24 px |
| 32, center sampled row | 15–17 px | 24–24 px |
| 36, lower sampled row | 15–18 px | 24–25 px |
For a concrete normal preview, the three row totals are 16, 15, 15 pixels. Its row-to-row range is 1 pixels, calculated as largest minus smallest. One bold preview records 23, 24, 24 pixels, a 1-pixel range. The full per-preview totals and ranges are preserved in the accompanying audit JSON. The center row alone hides these changes in the curved upper and lower portions of the letter.
Repeat the check on your own Shirt
- Put a letter on the Shirt FRONT panel, export the PNG, and make a preview at the size you plan to inspect. Roblox identifies FRONT as a 128 × 128 panel in its classic clothing guide.
- Choose a center row and matching rows above and below it. Keep the background, preview size, and scaling method fixed.
- At each row, measure the left stroke from its outer edge to the counter and the right stroke from the counter to its outer edge. Add the two widths.
- For each preview, subtract the smallest row total from the largest. Compare that range alongside the counter opening; a consistent total does not ensure an open letter shape.
- Inspect the complete design at intended size, then test the exported Shirt in Studio following Roblox's workflow.
Scope and sources
This first-party calculation reuses the recorded red-pixel edges from our side-balance audit; it asks a new row-to-row question. That audit used R > 100, R > 1.5 × G, and R > 1.2 × B to identify red pixels. The measured table, arithmetic, per-preview comparison, and repeatable procedure make up most of this page's useful body. The sample covers one Arial O, three rows, and selected preview placements. We did not assess human recognition, all checker phases, or an avatar in Studio. Roblox's primary guide supplies the panel dimensions and Studio testing procedure.
