Sewing pattern printed too small or too big? Learn which printer settings change the scale, how to fix them in common PDF readers, and how to check the result.
You printed the first page of a PDF sewing pattern, measured the test square and found it is a few millimetres short. This is one of the most common problems with print-at-home patterns, and it is almost always caused by a single setting. This guide explains why it happens and how to fix it on most computers and printers.
A PDF pattern is drawn at a precise scale. When you print, the software between the file and the paper can quietly resize the content. The usual causes are:
A small error matters more than it seems. A 4% reduction on a 100 cm hip measurement removes about 4 cm of ease, which can turn a relaxed pant into a tight one.
The names vary between programs, but the goal is always the same: print at 100% / actual size with no automatic resizing. Before printing a full pattern, check these in order:
Never print the whole pattern before checking the scale. Print only the page that contains the test square. On Digital Creation patterns, the cover page has a 5 cm test square and a 2 inch test square, and every page also has a 5 cm ruler, so you can check any sheet, not just the first.
Measure with a rigid ruler rather than a soft tape, and measure both width and height. If both measure exactly, print the rest. If they are still off, go back through the list above, because one setting is usually hiding in a second dialog box.
Sometimes the test square is correct but the tiles still do not match when you tape them. This is usually a paper feed issue rather than scaling:

If you live somewhere that uses A4 and you print a US Letter file, or vice versa, you may see clipping or scaling. It is always best to print the version that matches your paper. Our article on A4 vs US Letter for sewing patterns explains the differences and how to tell which one your printer uses.
This usually points to a printer driver setting, a paper size mismatch or a mechanical issue. Check that the paper size in the printer properties matches the file, then try another paper type. If it persists, the printer may need servicing, and a copy shop print may be quicker.
It is not recommended. Guessing a percentage rarely gives an exact result. Correct the settings and reprint at 100% instead.
No. Draft or economy mode only changes how much ink is used. It can make thin lines fainter, though, so use normal quality if the lines are hard to see.
Getting the scale right is the foundation of a good fit, together with accurate measurements; our measuring guide shows how to take them. Every Digital Creation pattern comes with test squares, page rulers and both A4 and US Letter files. Explore the designs and check the Pricing page to start downloading.
