DECISION GUIDE
How to use this result in a real decision.
How many full packs should be ordered after cuts and layout waste are allowed for? Convert the measured floor into order area first, then divide by the exact coverage per unopened pack and round up. Pack count—not raw square footage—is the purchasable result.
WORKED EXAMPLE
A 200 sq ft room with a 10% allowance
Inputs
200 sq ft measured area, 10% cutting waste and 24 sq ft of coverage per pack.
Calculated result
Order area is 220 sq ft. Dividing by 24 gives 9.17, so the purchase estimate is 10 packs covering 240 sq ft.
Decision meaning
The difference between 220 and 240 sq ft comes from whole-pack purchasing. Keep a suitable unopened pack only if the return policy and future repair plan support it.
Check before acting
Break L-shaped spaces into rectangles and include closets that receive the same floor.
Read coverage per pack from the selected product; piece dimensions alone may omit packaging assumptions.
Confirm batch or dye-lot consistency before mixing packs from different purchases.

How to use it
A better estimate in three steps.
01
Measure the longest length and width of the room.
02
Use the coverage shown on one flooring pack.
03
Choose waste based on room shape and laying pattern.
Core formula
The math behind the result.
Packs = round up[(room area × (1 + waste rate)) ÷ coverage per pack]
