Drywall Mud Calculator
Calculate joint compound, tape, and accessories for drywall finishing. Includes finish level 3, 4, and 5 estimates.
How to Use This Calculator
Joint compound (mud) estimation depends on the square footage, finish level, and number of joints. This calculator helps you determine how much mud, tape, and accessories you need for your drywall project.
- Enter total drywall square footage or number of sheets.
- Select the finish level required (Level 4 is most common for residential).
- Choose tape type - paper for best results, mesh for easier application.
- Enter corner bead linear feet if you have outside corners.
- Review quantities and adjust for your specific conditions.
Why This Matters
Running out of joint compound mid-project causes delays and can result in visible seams if different batches have slight color variations. Having adequate supplies ensures consistent application and proper drying time between coats. The finish level you choose dramatically affects both material quantities and final appearance.
- Calculate joint compound by finish level
- Determine tape quantities for all joints
- Include corner bead requirements
- Plan for primer after finishing
- Budget for complete finishing supplies
Worked Examples
Single Room
A 12x14 bedroom with 8-foot ceilings (walls only) using 14 sheets of 4x8.
Basement Finishing
1,200 sq ft of drywall including walls and ceiling, Level 4 finish.
High-End Level 5
500 sq ft dining room requiring Level 5 for glossy paint.
Common Mistakes to Avoid
- Underestimating for higher finish levels - Level 5 uses nearly double Level 4 amounts.
- Forgetting about screw and nail holes - these add significantly to compound usage.
- Not planning for corner bead - outside corners require extra material.
- Skipping primer - drywall compound must be primed before paint.
- Using wrong compound type - don't use all-purpose for first coat on mesh tape.
