Quick Sizing
How to take your photos:
- Place your hand flat on a table, palm down, fingers straight.
- Put a coin or credit/ID card on the table beside your fingers (not on your hand).
- Take photos straight from above — no angles.
- Use good light (daylight or lamp, no flash glare).
- Upload one photo of each hand; make sure the coin/card is fully visible.
Tip: A US quarter works best. Please avoid wide-angle lenses or zoom.
