How to use this chart

1 in = 2.54 cm

Find the inch figure in the first column and read the centimetre figure across.

Common sizes are easy to spot: 55 in is 139.7 cm and 32 in is 81.28 cm.

About the Inches to Cm Chart

Screens, timber, paper and clothing all mix inches and centimetres, often in the same shopping trip. A 55 inch television is 139.7 cm across the diagonal, and 2 by 4 timber is sold as 50 by 100 mm in metric countries, which is not the same as 2 in by 4 in sawn.

The metre column is handy for furniture: a 40 inch desk is 101.6 cm wide, just over a metre, and that is the number that decides whether it fits a room.

Diagonal measurements follow the same rule, which is why a 65 inch television is 165.1 cm corner to corner but only about 144 cm wide. The chart gives the diagonal; the bezel and aspect ratio determine the width.

For paper, the inch figures matter less than the standard: A4 is 8.27 by 11.69 in, which is close to but not the same as US Letter at 8.5 by 11 in. The chart helps confirm that difference rather than assume the two are equal.

How the calculation works

  • centimetres = inches × 2.54
  • metres = inches × 0.0254
  • 55 in (television diagonal) = 139.7 cm
