How to convert inches to cm
Multiply inches by 2.54. To convert centimeters back to inches, divide by 2.54. The conversion is exact; only the displayed rounding changes. Convert width and height separately for rectangular papers or photographs.
Is 12x12 paper the same as 30x30 cm?
Not exactly. A 12x12-inch scrapbook page is 30.48x30.48 cm. Paper sold as 30x30 cm is about 11.81x11.81 inches, so it is slightly smaller on every side. This matters when fitting page protectors, cutting borders, or printing at 100 percent scale.

Frequently asked questions
How many centimeters is one inch?
One inch is exactly 2.54 centimeters.
Should I round before printing?
Keep at least two decimal places while planning, then use the printer size that the application accepts. A small rounding difference is usually harmless, but “fit to page” can change scale more noticeably.
