Flooring & surfaces

Flooring Calculator

Estimate laminate, luxury vinyl plank, or hardwood flooring for one room, several areas, or a known total.

What floor are you planning?

How is your flooring area measured?

Measurement system

Flooring type changes the guidance only. It never changes the formula or allowance automatically.

How is your flooring area measured?

Enter the total area before subtracting any exclusions.

Subtract permanent exclusions

Add rectangular zones that will not receive flooring, such as a fixed cabinet footprint. Do not subtract temporary furniture.

Exclusion 1
Exclusion length
Exclusion width

Up to 20 exclusions can be entered.

Manufacturer coverage per box

Actual plank length
Actual plank width

The 10% starting allowance is editable. The recommendation for your exact product and installation pattern should always take priority.

Use the manufacturer coverage printed for the exact box or carton. Leave it unavailable if you have not chosen a product yet.

Plank dimensions are optional and independent from box coverage. Use actual fixed product dimensions, not a nominal category size.

How it works

How your measurements become a flooring order.

We total the gross rectangles, subtract permanent exclusions, apply your extra-material allowance, then use exact product details only when you provide them.

Measured flooring area

Measured area = gross area − exclusions

Multiple rooms and exclusions are each totaled from their exact rectangular measurements and quantities.

Extra material

Order area = measured area × (1 + allowance %)

The allowance remains a user choice and is never changed automatically by flooring type.

Boxes

Boxes = round up(order area ÷ manufacturer box coverage)

Box results appear only when coverage per box is provided.

Plank count

Plank equivalent = area ÷ actual plank area

Plank results appear only for products with fixed dimensions you enter.

Before you buy

What this estimate assumes

  • Every entered room, area, and exclusion is rectangular and non-overlapping. Exclusions are subtracted from the project total rather than assigned to a specific room.
  • The default 10% extra-material allowance is an editable planning value. Product instructions and the chosen layout or pattern should take priority.
  • Laminate, luxury vinyl plank, and hardwood use the same area formulas. Flooring type changes guidance only.
  • Coverage per box and fixed plank dimensions are independent optional inputs. Manufacturer box coverage remains authoritative for box purchasing.

Use the exact product specifications

Box coverage, board dimensions, installation layouts, and recommended overage vary by product. Confirm the packaging and current installation guide for the exact flooring you plan to buy.
