How to Choose the Right Round Stamp Size

The right diameter depends on your artwork, not on the stamp body. Four questions we ask every buyer before recommending a size:

• Logo complexity — fine lines and small icons stay crisp at 30–38 mm; detailed emblems need 42 mm and up
• Amount of text — one ring of company name fits 38 mm; a second ring or a registration line usually means 42–50 mm
• Company name length — long names need more arc length; we typeset longer names on 45 mm or 50 mm for readability
• End use — desk stamps for daily paperwork stay compact (30–40 mm); official and certification seals go large (42–50 mm)
