PDF Size Highlighter
Pattern PDF doesn't have separate layers? Upload it here, select your size, and download a version with your size clearly highlighted — coloured markers, edge strips, and corner callouts.
Upload your pattern PDF
Works with patterns that have nested size lines with size labels printed on them (e.g., 34, 36, 38, S, M, L). The tool detects which sizes are present and adds visual markers to help you identify your size.
How it works
- Upload a sewing pattern PDF that has nested sizes without separate layers
- The tool scans the PDF and detects which size labels are present
- Select your size(s) and a highlight colour
- Download a new PDF with your size clearly marked — coloured edge strips, size callouts in the corners, and a legend showing your selected sizes
This tool adds visual markers to help you identify your size lines. It works especially well with patterns from Merchant & Mills, Fibre Mood, and other brands that use nested sizes without colour coding or separate layers.
Why some patterns need this
Many pattern companies — especially European brands like Merchant & Mills, Fibre Mood, and some indie designers — ship their PDF patterns with all sizes nested on the same layer. Unlike brands that use separate PDF layers (which our Layer Toggle tool handles), these patterns require you to visually identify your size line among many overlapping lines.
The size lines are usually differentiated only by small text labels (34, 36, 38, etc.) placed along the cutting lines. On a large A0 print or when projecting, it can be very difficult to follow your size line across the full pattern piece.
Tips for working with nested sizes
Print in colour if possible. Even though the pattern is all one colour, the highlighted version from this tool adds coloured markers that make your size stand out.
Use a highlighter on the printed pattern. After printing, physically trace your size line with a highlighter or coloured pen. Start at the size label and follow the line around the entire piece.
Cut between sizes if you're grading.If your bust is size 40 and your hip is size 44, you'll need to blend between the two lines. Select both sizes in this tool to see where they are.
For projector sewing: The coloured edge strips on the highlighted PDF make it much easier to see which size is which when projecting, even at a distance.
