Buttonhole Spacing Calculator
Calculate even buttonhole placement and spacing for garments
About this calculator
The Buttonhole Spacing Calculator helps sewers and tailors determine the optimal placement and spacing for buttonholes on garments. This tool ensures professional-looking results by calculating even distances between buttonholes based on your garment measurements and number of buttons. Whether you're creating a shirt, jacket, or dress, proper buttonhole spacing is crucial for both functionality and aesthetic appeal, preventing fabric bunching and ensuring buttons align perfectly with the garment's design.
How to use
Enter your garment's button band length and the total number of buttonholes needed. The calculator will automatically determine the optimal spacing between each buttonhole and provide measurements from the starting point. Use these measurements to mark buttonhole positions on your fabric before sewing for perfectly aligned results.
Frequently asked questions
How much space should I leave from the garment edges?
Typically leave 1/2 to 3/4 inch from neckline and hem edges, though this varies by garment style and button size.
Should buttonhole spacing vary by button size?
Yes, larger buttons need more space between buttonholes to prevent overlap and fabric stress. Consider button diameter plus seam allowances.
What if my calculated spacing looks too wide or narrow?
Adjust your button band length or button count. The spacing should look proportional to your garment and button size.
