FAQ
What does this trim size checker do?
It compares your entered width and height against common KDP paperback trim sizes and flags whether your dimensions match a supported size.
Does a match guarantee KDP will accept my file?
No. Trim size is one requirement. KDP also validates margins, bleed, cover dimensions, and PDF settings separately.
Why do some trim sizes use decimals like 5.06 x 7.81?
KDP lists trim sizes in inches with fractional equivalents of metric standards. Always use the exact dimensions KDP specifies for your chosen size.
