A little measuring.
A lot more clarity.
A tape measure, a simple sketch and a few photos are a useful start. You don’t need a perfect floor plan to talk to us.
Give unusual shapes a plan.
Split an L-shaped room into two rectangles with no overlap. For more complex rooms, add each rectangle separately and give it a clear name.
Area A + Area B = room area
Leave the final checks to us.
Photograph doorways, transitions and existing floors. Mention stairs, seams, patterns and areas you could not measure.

Area is a starting point. Product choice, preparation and installation details complete the plan.

Measure a rectangular room’s length and width, then multiply them using the same unit. A room 12 feet long and 10 feet wide has 120 square feet of floor area. Measure each room separately and add the areas for your project total.
How do I measure an L-shaped room?
Split the L into two adjoining rectangles that do not overlap. Measure the length and width of each rectangle, calculate each area and add them together. Include closets or recesses as separate rectangles when they need flooring.
How do I enter feet and inches?
Use the separate feet and inches fields. For 12 feet 6 inches, enter 12 in feet and 6 in inches. Inches are divided by 12 before calculating the area. You can also choose metres; results include square feet and square metres.
How much extra flooring should I allow?
The right allowance depends on the product, room layout, cuts, installation direction, patterns and spare material. This planner lets you compare an optional 5%, 10% or 15% allowance. These are scenarios, not a recommendation or final order quantity. Mago reviews the layout and manufacturer requirements before ordering.
Can I use this calculator for carpet?
You can use it to estimate the room’s floor area. Carpet ordering also depends on roll width, seams, pattern repeats, direction and stairs. A floor-area total alone does not determine how much carpet to buy. Share your room measurements for a carpet layout review.
Does this include stairs, walls or installation pricing?
No. The planner measures horizontal rectangular floor areas. Stairs, wall tile, baseboards, preparation, repairs and installation costs need separate measurements and scope. Add those details to your estimate request.
Can Mago check my measurements?
Yes. Include your town, approximate measurements and the flooring you are considering in an estimate request. Mago serves Massachusetts and reviews qualifying Rhode Island and New Hampshire projects. The team confirms measurement needs, scope and visit availability directly.
