Total carpet area 2.04 m² divided by 4 m roll width = 0.51 m of roll length. Room width fits within a single drop at this roll width.
How this calculator works
Step 1
Measure the room
Enter the longest length and widest width of the room in metres or feet.
Step 2
Select roll width
Choose 4m or 5m (or your stock width) to see whether a single drop covers the room.
Step 3
Add waste allowance
Apply a waste percentage for cuts, pattern match and fitter tolerance before ordering.
When to add more waste
- Pattern match or large repeat — add 10–15%
- Hall, stairs and landings combined — 10–15%
- Awkward rooms with many cuts — 15–20%
Why use this free calculator?
- Get instant carpet area estimates without spreadsheets or manual maths.
- Account for roll width early so joins and waste are visible at quote stage.
- Share clear quantities with customers and fitters before ordering.
Common mistakes to avoid
- Measuring only the centre of the room, missing alcoves
- Forgetting waste for joins on wide rooms
- Quoting net area without explaining waste to the customer
