Edge Sealant Quantity Calculator

Estimate the amount of wet-glaze edge sealant required from total window perimeter, bead size, and package type. Calculations assume a 45° triangular bead and include a 10% waste allowance by default.

A 1/4" × 1/4" triangular bead uses approximately 0.208 fl oz per linear foot before waste.

Calculation: the bead is modeled as a perfect right triangle: area = ½ × bead width × bead depth. Total bead volume is converted from cubic inches to U.S. fluid ounces, then the selected waste allowance is added.
