Buttonhole Spacing Calculator
Calculate even spacing for buttonholes on garments
About this calculator
The Buttonhole Spacing Calculator helps sewers and tailors achieve perfectly even buttonhole placement on garments. This tool eliminates guesswork by calculating precise measurements between buttonholes based on your garment's dimensions and desired number of buttons. Proper buttonhole spacing ensures professional-looking results and prevents uneven gaps that can ruin a garment's appearance. Whether you're making shirts, jackets, or dresses, this calculator saves time and reduces measuring errors for consistently beautiful buttonhole placement.
How to use
Enter your garment's total button band length and the number of buttonholes you need. The calculator will determine the exact spacing between each buttonhole center point. Mark these measurements on your fabric using a ruler or measuring tape, then sew your buttonholes at the calculated intervals for perfectly even spacing.
Frequently asked questions
How do I measure the button band length?
Measure from the top edge to bottom edge of where buttons will be placed, excluding seam allowances and hem areas.
Should I include buttonhole length in spacing calculations?
No, the calculator determines center-to-center spacing. The actual buttonhole length doesn't affect the spacing between buttonhole centers.
What's the standard buttonhole spacing for shirts?
Shirt buttonholes are typically spaced 2.5-4 inches apart, but use the calculator for precise measurements based on your specific garment dimensions.
