What density-preserving embroidery resizing can do

Why a larger outline can sew differently

When coordinates move farther apart, the spacing between neighboring stitch rows can grow too. Shrinking can crowd stitches into a smaller area. Lettering, small details and underlay can respond differently from broad fills.

There is no universal safe percentage that guarantees identical results across every file, fabric and stitch construction.

What is missing from a machine file

A machine file contains stitch movements and commands. It may not identify which movements were satin, which formed a fill, which were underlay, or which settings created them. Different constructions can produce similar coordinates.

A reconstruction algorithm must infer that information. That is useful, but it is not equivalent to having the original objects and stitch parameters.

Choose the best source for the change

If you have the original project, change the dimensions there and regenerate stitches. If only a machine file remains, keep a backup and inspect the resizer's warnings and preview.

For small text or a substantial change, consider re-digitizing the affected elements. Preserving an outline while losing readable lettering is not a successful resize.

Compare before and after

Check the new physical dimensions, number of stitches, small gaps, overlaps and line width. Do not expect stitch count to scale in the same way for every region.

Test the actual final size on your intended material. A preview helps identify obvious problems but cannot reproduce fabric movement or tension.
