Start with the tool that matches your task. Replace the example values with your own details, then use the result alongside product instructions and measurements taken in the room.
1. Choose the right tool
Search by material or task, or browse the categories. Read the description and method before entering values: a floor-area estimate, for example, is not necessarily a complete flooring order.
2. Prepare your measurements
Measure more than once and use the units shown beside each field. Convert measurements before entering them rather than mixing feet with metres or inches with centimetres. The prefilled values are examples, not measurements of your room.
For an irregular space, consider measuring separate rectangles when the method allows it. Check how the tool handles openings, waste, coats, and coverage so that you do not add or subtract the same allowance twice.
3. Calculate and read the result
Select Calculate / Generate. If a field shows an error, correct the value and try again. If your form session has expired, refresh the page before resubmitting; you may need to enter your values again.
Read the result labels, units, notes, and worked example. A suggested size, colour, or layout reflects the rules and choices used by that tool, not an assessment of every feature of your room. Try different inputs to see how the estimate changes.
4. Turn an estimate into a checked plan
Keep your own note of the inputs, assumptions, and result. Check pack sizes, usable dimensions, coverage, pattern repeats, delivery charges, and installation instructions with the supplier before ordering. Round quantities to available purchase sizes where appropriate.
Confirm clearances and access routes in the actual room. For structural changes, electrical work, plumbing, or other safety-critical decisions, ask a suitably qualified professional rather than relying on a calculator.
