Before: 94 mm × 75.59 mm. After: 150 mm × 120.62 mm.

Preview of your resized SVG

If the file holds separate pieces, the new size is the whole file, not the finished piece. Why an SVG imports at the wrong size.

Resize a batch by percentage

Each file needs a stated size (mm, inches or pixels) that matches its drawing’s proportions. Any file we can’t resize is listed with the reason.

Your original files stay as they are.

Change the size, keep the drawing

An SVG has two sizes: the width and height your software reads, and the viewBox, the drawing’s own grid. This tool changes only the width and height, so the drawing scales evenly and nothing inside it moves. The file needs a viewBox already. The tool can’t trim empty space, fix paths or set cut and score lines. With Keep proportions off, a size that doesn’t match the drawing’s shape adds space around it, or crops it in some programs; it never stretches the drawing.
