What is the Carpet Calculator?

Carpet is sold by the linear metre from a roll of fixed width — usually 3.66 m or 4 m — which means you need to think about the room layout, not just the floor area. An irregular room or a carpet with a pattern repeat can significantly increase waste. This calculator converts your room dimensions and carpet roll width into the exact linear metres you need to order, including a seam adjustment factor.

You may also find the Laminate Flooring Calculator, Carpet Calculator, and Wallpaper Calculator useful.

Who Uses This Calculator?

This tool is used by homeowners replacing carpet, interior designers specifying flooring, and carpet retailers quoting jobs.

How to Use the Carpet Calculator

<öl>
  • Enter your Room length.
  • Enter your Room width.
  • Enter your Carpet roll width.
  • Enter your Pattern repeat.
  • Click Calculate to see your results instantly.

    • Formula

    The calculator uses the following formula:

    Room area = Length × Width; Linear metres = ceil(area ÷ roll_width × adjustment_factor)

    Worked Example

    A 5 m × 4 m room carpeted with a 4 m wide roll requires 5.5 linear metres (with no pattern repeat). Adding a 30 cm pattern repeat increases this to about 6.1 linear metres.

    Step-by-Step Calculation

    <öl>
  • Room area: 5 m × 4 m = 20 m²
  • Roll width: 3.66 m (standard 12 ft roll)
  • Linear metres from roll: ceil(20 ÷ 3.66) × 3.66 = ~21.96 m
  • Add 10% for cuts and seams: ~24 linear metres

    • Common Mistakes to Avoid

    • Measuring the room and buying exactly that area — seams and cuts waste 10-15%
    • Forgetting to add extra for pattern matching (pattern repeat × number of drops)
    • Not accounting for door and bay window recesses
    Pro Tip: Always run carpet pile in the same direction throughout a room — rotating it creates visible shading differences. For L-shaped rooms, calculate each section separately and combine the totals.

    Frequently Asked Questions

    Why is carpet sold in linear metres, not square metres?

    Carpet comes off a roll of fixed width. The supplier cuts you a length of that roll. The linear metre price multiplied by the roll width gives the effective price per square metre.

    What carpet roll widths are available?

    The most common widths are 3.66 m (12 ft) and 4.57 m (15 ft) in the US/UK, and 4 m in metric markets. Some ranges come in 5 m rolls for large rooms.

    How does pattern repeat affect carpet quantity?

    With a pattern repeat of 30 cm, each strip must be aligned to the pattern before cutting, adding waste. The longer the pattern repeat, the more waste. Plain or textured carpets have zero repeat.

    Can I lay carpet over underlay?

    Yes — underlay is recommended under all broadloom carpet. It extends carpet life, improves comfort and insulation, and reduces noise. Calculate underlay area the same way as carpet area.

    How much extra carpet should I order?

    Standard advice is 10% extra for seams, cuts, and future repairs. In rooms with many angles or alcoves, add 15%. Always save off-cuts for patch repairs.
