📏 Flooring Calculator

Estimate how many boxes of vinyl planks, laminate flooring, or hardwood flooring you need based on room size and product coverage.

Estimate how many boxes of flooring you need before purchasing materials.

Step 1: Calculate Room Size

Room Length × Room Width = Room Size (sq ft)

Example:

12 ft × 15 ft = 180 sq ft

Step 2: Calculate Boxes Needed

Room Size ÷ Coverage Per Box = Boxes Needed

Example:

180 sq ft ÷ 27 sq ft per box = 6.67 boxes

Step 3: Round Up

You cannot buy part of a box.

6.67 boxes = 7 boxes needed

Recommended

Add 10% extra for cuts, mistakes, and waste.

180 sq ft + 18 sq ft = 198 sq ft

198 ÷ 27 = 7.33 boxes

Result

✅ Minimum Purchase: 7 boxes

✅ Recommended Purchase: 8 boxes

🧱 Drywall Calculator

Calculate how many drywall sheets you need for your room walls.

Example

Room Length = 12 ft

Room Width = 15 ft

Room Height = 8 ft

Wall Area

(12 × 8 × 2) + (15 × 8 × 2)

= 432 sq ft

Drywall Sheets Needed

432 ÷ 32

= 13.5 sheets

Round Up

14 sheets needed
