Collar pattern guide
Printable collars matched to the finished neckline
The generator converts the finished neckline length, collar style, stand height, fall height, overlap, roll allowance, and seam allowance into full-size collar pieces. Use these notes to choose the right collar type and verify it against the bodice, dress, or shirt neckline before cutting.
Neckline length, stand height, fall height and overlap
Use the finished garment neckline measured along the stitching line after shoulder seams and seam allowances are accounted for. Stand height controls the neck band; fall height controls the visible collar leaf.
Shirt collar, stand collar or flat collar
A shirt collar uses a separate stand and collar leaf, a stand collar is a clean band around the neck, and a flat collar sits closer to the garment neckline with minimal stand.
Match the collar to the prepared neckline
Do not use raw body neck circumference as the final collar length. Measure the actual bodice, dress, or shirt neckline along the seam line and test the collar before cutting final fabric.
Check roll, interfacing and button overlap
Collars are sensitive to fabric thickness and interfacing. Test the roll line, stand curve, overlap, button placement, and seam allowance on a sample if the garment neckline is shaped or the fabric is bulky.
A4 tiled PDF, copyshop PDF or SVG
Print at actual size or 100% with scaling disabled and measure the test square first. Use tiled A4 at home, copyshop PDF for a full-size sheet, or SVG for vector editing.
Common questions
Collar pattern FAQ
Is the collar pattern generator free?
Yes. Enter the collar measurements, preview the generated pieces, and download SVG, copyshop PDF, or tiled A4 PDF without purchasing a fixed-size pattern.
Should I use neck circumference or neckline length?
Use the finished garment neckline length measured along the stitching line. Body neck circumference is useful context, but the collar must match the actual neckline it will be sewn to.
What is the difference between a shirt collar and a stand collar?
A shirt collar has a collar stand plus a separate collar leaf that folds over. A stand collar is only the band around the neck and does not include a fold-over collar leaf.
What is roll allowance?
Roll allowance gives the collar leaf extra room to fold over the stand without pulling. It matters most for shirt collars with interfacing or thicker fabric.
How should I print the A4 collar pattern?
Select actual size or 100%, disable fit-to-page scaling, and measure the 5 × 5 cm test square before cutting the printed collar pieces.
