**To calculate number of boxes of flooring do you need for 400 square feet, let’s proceed and do the following calculation:**

**Amount of Laminate flooring for 400 square feet**

● No. of laminate flooring = 400/ 30 = 14 boxes

● 10% waste factors i.e 10% of 14 = 2 boxes

● Add 10% in initial estimate = 14+2 = 16 boxes.

**Amount of Vinyl planks flooring for 400 square feet**

● No. of Vinyl flooring = 400/ 18 = 23 boxes, or 400/ 25 = 16 boxes, or 400/ 20 = 20 boxes on average.

● 10% waste factors i.e 10% of 23 = 2 boxes, or 10% of 16 = 2 boxes, or 10% of 20 = 2 boxes

● Add 10% in initial estimate = 23+2 = 25 boxes or 16 +2 = 18 boxes, or 20+2 = 22 boxes on average.

Hardwood flooring is sold by the carton, generally 20 square feet. All hardwood flooring requires a percentage of waste to be added for installation. The general rule is to add 10% for installations. Using an example of 400 square feet projects, we can figure our allowance for 10% waste by multiplying 400 x 10% to get 40, so we will need to purchase 440 square feet of hardwood. If the product we selected has 20 square feet per carton, then divide 440 by 20. We get 22, so we will want to round up and purchase cartons.

You will need approximately 440 square footage or 16 boxes of laminate flooring for 400 square feet. Each box of laminate flooring will cover about 30 square feet.
