How to Print PDF Sewing Patterns: Check Both Sides of the Test Square

Before printing your full PDF sewing pattern, check the labelled test square across its width and height. This first episode of Sewlore Sewing Notes explains how to select the correct paper format, review scale settings, and interpret unequal readings without treating print enlargement as a sizing method.The worked example is illustrative: a 100 mm reference printed at 98 mm wide and 101 mm high has a -2% width error and a +1% height error. A single overall scale adjustment cannot correct both axes at once. Follow the printing instructions and any tolerance supplied with your own pattern, then print and measure a fresh test page.Resources from Sewlore:PDF sewing pattern printing and assembly: https://sewlore.com/pages/printing-assemblyPDF Pattern Print Scale Checker: https://sewlore.com/pages/pdf-pattern-print-scale-checkerCheck both directions and troubleshoot unequal scaling: https://sewlore.com/blogs/sewing-journal/check-pdf-pattern-print-scale-both-directionsNarration disclosure: This episode uses a synthetic voice.
