Image & Print Size
CM to Inches Converter (Print)
Convert centimetres to inches for print sizes, with optional 300 DPI pixel width.
Rounding too early is a common reprint cause — keep two or three decimal places for file setup, then round only on the customer-facing quote.
How it works
inches = centimetres ÷ 2.54 (exact by definition).centimetres = inches × 2.54.
Optional pixels at 300 DPI = inches × 300.
Use the result in Inches to Pixels or the T-Shirt Print Size Guide before you place art on a garment template.
Worked example
A client wants a 30 cm chest print. 30 ÷ 2.54 ≈ 11.81 in. At 300 DPI that is about 3543 px wide. Building a “12 inch” file is close — but 11.81 in is what they asked for.Common apparel widths
| cm | in (approx) |
|---|---|
| 10 cm | 3.94 in (left chest range) |
| 28 cm | 11.02 in (full front) |
| 35 cm | 13.78 in (large back) |
