Vinyl flooring calculator

How to use the vinyl flooring calculator

Estimate how much vinyl flooring to buy for a rectangular room. Choose boxed vinyl plank or sheet vinyl, enter the room size and product details, and get the quantity with waste included.

1. Choose the Unit system: Feet / inches or Metres / cm.
2. Enter Length and Width, including any plus inches or centimetres. You can enter Or a known area for plank flooring instead.
3. Set Product to plank or sheet. Enter Coverage per box for plank, or choose the sheet vinyl Roll width.
4. Adjust Waste % and add Price per box (optional) or Include underlayment if needed.
5. Review the boxes, sheet area, linear material, cost, and underlayment rolls shown in the results.

What to enter

Unit system

Choose Feet / inches or Metres / cm. Imperial is the default.

Length

Room length. The default is 12 ft in imperial mode or 12 m in metric mode.

plus inches

Add inches to Length in imperial mode, or centimetres in metric mode. The default is 0.

Width

Room width. The default is 10 ft in imperial mode or 10 m in metric mode.

plus inches

Add inches to Width in imperial mode, or centimetres in metric mode. The default is 0.

Or a known area

Optional floor area. It uses sq ft in imperial mode or m² in metric mode and overrides Length × Width for plank flooring. Sheet mode uses Length and Width instead.

Product

Choose plank or sheet. The default is plank. Plank uses cartons; sheet uses material cut from a roll.

Coverage per box

Coverage printed on the carton. The default numeric value is 24 sq ft in imperial mode or 24 m² in metric mode. It applies to plank flooring.

Roll width

Sheet vinyl roll width. Choose 6 ft or 12 ft; 12 ft is the default. These choices remain feet-based in metric mode.

Waste %

Extra material for cuts and waste. The default is 10%. Enter a value from 0% to 50%.

Price per box (optional)

Optional non-negative price for each box. The calculator adds a material cost for plank flooring; sheet mode does not use this value.

Include underlayment

Turn this on to estimate rolls of underlayment for the purchase area. The default is off.

Underlayment coverage per roll

The default numeric value is 100 sq ft per roll in imperial mode or 100 m² per roll in metric mode.

Reading the results

For plank, Boxes to buy is the whole-carton quantity after waste. The results also show the floor area and Area to purchase. If a price is entered, Material cost equals whole boxes × price per box. For sheet, Linear feet off the roll shows the material length needed after waste. Its unit is ft in imperial mode and m in metric mode. Sheet vinyl purchased shows the roll area to buy in sq ft or m². The results also show the selected strip count and any underlayment rolls.

Limitations and common mistakes

• Sheet mode calculates from Length and Width. It does not use Or a known area.
• Price per box (optional) produces a cost only for plank flooring. Sheet mode does not calculate a sheet-vinyl price.
• The Product input controls the mode and accepts plank or sheet. A separate value named Format does not switch the calculation.
• The calculator models a rectangular area. Irregular rooms, separate rooms, pattern repeats, and extra cuts may require additional planning. Coverage defaults are unit-sensitive: 24 means 24 sq ft in imperial mode or 24 m² in metric mode, and the underlayment default is 100 sq ft or 100 m² respectively.
