Getting Accurate Floor Measurements
Measure wall to wall at floor level, at the longest and widest points of the room. If the walls are not straight, take the larger measurement. For rooms with bays, alcoves or a step, the custom shape option lets you add each part as its own section.
Your total floor area helps us price materials and labour, but every installation also depends on the subfloor, the pattern you choose and access to the property. That is why we always confirm the details before we finalise your quotation, and why we offer free site surveys and video call surveys across London, Essex, Kent and Surrey.
Flooring Calculator Questions
How do I measure a room for new flooring?
Measure the longest length and widest width of the room in metres or millimetres. For L-shaped rooms, measure the overall size and the cut-out. For odd shapes, split the room into rectangles and add them in the custom shape option.
Should I add extra flooring for waste?
Yes. Cutting and pattern matching mean you need more than the exact floor area. Herringbone and parquet patterns usually need more allowance than straight-lay planks. We add the right allowance for your chosen floor when we prepare your quote.
Does the calculator include doorways and alcoves?
Use the custom shape option to add alcoves and bay areas as extra sections, and tick Subtract for anything that will not be floored, such as a fitted kitchen island or chimney breast.
What happens after I send my measurements?
Your room sizes, notes, subfloor details and photos come straight to our team. We review them and come back to you with a free quotation, or arrange a site survey or video call if we need to check anything.
Why do you ask about the subfloor?
The type and condition of the subfloor, usually concrete or wood, affects the preparation needed before your new floor is fitted, such as moisture testing, smoothing compounds or plywood overlays.
