Button Spacing Calculator — Even Button Placement

Measure the total button band length, subtract the offset from each end, then divide the remaining length by (number of buttons minus 1). This gives the distance between each button. The top and bottom buttons should be offset from the edges.

Typically 1-2cm from each end. The exact position depends on the garment design. For cardigans with a collar, the top button is usually further from the edge (3-5cm) to allow the collar to fold.

A standard adult cardigan uses 5-8 buttons depending on length. A short cropped cardigan may need only 3-4. A long coat-style may need 8-10. Space buttons every 7-10cm for a balanced look.

Yes. Sew buttons on the button band first, then use those positions to place buttonholes on the opposite band. This ensures perfect alignment. Pin or mark all positions before knitting any buttonholes.

Multiply the position in cm by your row gauge per cm. For example, a button at 8cm with 3 rows per cm means the buttonhole goes on row 24. Round to the nearest row.
