How to Use This Calculator
- Enter the Opening Width and Opening Height in feet for the storefront system.
- Enter Division Spacing for vertical mullion centers and the number and size of door openings.
- Review Vertical and Horizontal Mullion counts and Total Framing in linear feet.
- Check Glass Lites count and Door Frames needed to complete the takeoff.
- Use Total Estimated Weight to verify structural header capacity above the storefront opening.
How the result changes with Opening Width
