Rule and assumptions
Pocket logo width = left-chest safe width x pocket factor. Height = width / aspect ratio. Factors are starting points.
- Pocket dimensions vary by brand and should be measured before production.
- The calculator gives a planning size, not a universal template.
Use this tool for
- Estimating pocket logo size for adult and youth shirts.
- Keeping small text readable inside a chest pocket area.
- Comparing faux pocket placement with a real raised pocket.
- Preparing a pocket-safe copyable result before cutting HTV.
Worked example
Inputs
- Unit: inches
- Shirt size: Adult M
- Pocket type: standard chest pocket
- Design aspect ratio: 1
Result
A standard Adult M pocket logo starts near 3.17 in wide by 3.17 in high, then should be checked against the actual pocket width.
When to use this
Use this when a left chest mark needs to sit visually inside a pocket area instead of using a full left chest size.
What to check before pressing
Measure the pocket opening, avoid raised seams, and simplify small lettering before cutting or printing.
Quick reference chart
| Use case | Starting point | Check before pressing |
|---|---|---|
| Adult pocket | 2.75 to 3.5 in wide | Check pocket edge before pressing |
| Youth pocket | 2.25 to 3 in wide | Keep text bold |
| Toddler pocket | 1.75 to 2.5 in wide | Avoid tiny thin text |
Common mistakes
- Treating a pocket logo like a full left-chest logo.
- Using thin text that becomes unreadable at pocket scale.
- Pressing over a raised pocket seam.
