This scale reference table shows the real (full-size) length for a range of measured (scaled) size values, assuming a scale factor (1 : n) of 87. Every figure is computed with the same engine that powers our Scale Calculator, so the numbers are exact.

How to use this table
Find the row closest to your measured (scaled) size and read across to the real (full-size) length. For a value between two rows, the real figure sits between them — or enter your exact numbers in the Scale Calculator for a precise answer.
Need a value that is not in the table? — the Scale Calculator does it instantly, for free, with the formula and a worked example built in.
