Drywall Calculators: Every Tool You Need for Hanging and Finishing
A drywall estimate has more moving parts than it first appears — sheet count depends on total area and sheet length, but screws, tape, joint compound, and corner bead each scale off different underlying numbers (sheet count, seam length, corner count) rather than off square footage directly. Mixing those up is one of the most common ways a drywall order comes up short.
This page brings together all 8 of our free drywall calculators, from basic sheet count through fire-rated assembly layers and texture spray coverage. Each links to a full guide covering the finishing-level distinctions, screw patterns, and code-related caveats that matter for getting an accurate order.
All Calculators & Guides
Drywall Sheets Calculator

Estimate material and labor cost per square foot, including finish-level pricing differences.
Drywall Screws Calculator
Calculate total screws, weight, and box count based on sheet count and fastening pattern.
Drywall Joint Compound & Tape Calculator
Calculate mud buckets and tape rolls needed, and how coat count changes each.
Corner Bead Calculator
Calculate linear footage and stick count of corner bead for outside drywall corners.
Metal Stud Framing Calculator
Calculate stud count and track footage for a metal-framed wall at standard spacing.
Fire-Rated Drywall Layer Calculator
Estimate sheet count for 1-hour and 2-hour Type X fire-rated wall assemblies.
Drywall Texture Spray Coverage Calculator
Calculate texture mix boxes needed, including the overspray waste factor hopper guns lose.
Frequently Asked Questions
Which drywall calculator should I use first?
Start with the Drywall Sheets Calculator — sheet count is the input the Screws Calculator and cost estimates are built from, so it’s the natural starting point for any drywall order.
Do the mud and tape calculators scale together?
No, and this is a common mix-up — joint compound scales with coat count, but tape only goes down once during the embedding coat, so tape quantity stays the same even if you add more finish coats.
Can I use the fire-rated calculator to confirm code compliance?
No — it estimates material quantity only. The exact assembly (layer count, joint staggering, fastener pattern) must be verified against your local code official’s required UL or GA listing before construction.
