The calculator

Add your rooms

Measure each space at its longest and widest points, closets included. An L shaped room splits into two rectangles. If you already know an area, enter it directly.

Stairs, if you have them

Each step is figured as its tread plus its riser, across the stair's width. Landings count as their own small area above.

Cuts and waste

Every cut at a wall leaves an offcut, and many are too short to reuse. The more complex the layout, the more the room asks you to order. These presets follow the rule of thumb installers work from.

Coverage per box is printed on the product label and differs product to product, so we leave that field to you. Carpet and sheet vinyl come in wide rolls rather than boxes: the square footage here still holds, and the roll layout and seam plan get drawn at the measure. Repeating patterns can add more for pattern matching.

What this number is, and what it is not

This calculator does honest arithmetic on the numbers you give it, and that makes it a genuinely useful planning figure: enough to compare materials seriously, sanity check a quote, or know whether a roll end could cover your laundry room. What it cannot see are the things that change a material list in person. Doorways and how much room is left under each door once a new floor adds height. Transitions, meaning every place one floor meets another. The subfloor, and whether it needs leveling or patching before anything goes down. Which direction the planks should run, where seams will fall, and how much waste the pattern really carries in your room rather than in a preset.

That list is not ours to guess at, and it is exactly what the free in-home measure exists to settle. One visit, a tape measure and a straight answer, and the measure is the number we order from. If you want to understand what moves a quote before anyone visits, our page on what decides a flooring quote walks through every factor in plain language.

Measure a room in three minutes

  1. Run the tape along the longest wall, baseboard to baseboard, and write down feet and inches. That is your length.
  2. Do the same across the widest span for your width. For an L shaped room, treat it as two rectangles and measure each on its own.
  3. Open every closet door. Closets get flooring too, and forgetting them is the most common reason a self-measured order runs short. Add each one as its own small area.

Round up, never down, and let the waste allowance do its job. When the tape has to bend around something unusual, measure the widest points and mention the odd shape when you get in touch: odd rooms are normal rooms to us.

Questions about measuring for flooring

Straight answers on square footage, waste and what the calculator can and cannot know.

Measure the longest wall for length and the widest span for width, baseboard to baseboard, then multiply the two. Measure closets separately and add them, because they get flooring too and forgetting them is the most common reason a self-measured order runs short. For an L shaped room, treat it as two rectangles and add them together.

It depends on the layout. A straight lay parallel to the wall wastes the least, a diagonal run or a large format tile wastes more, and a herringbone or intricate pattern wastes the most because every angled cut leaves an offcut too short to use. The calculator applies a sensible allowance for each, and you can set your own percentage instead.

No, and that is deliberate. It gives you quantities: square footage, how much to order with waste included, and boxes once you enter the coverage printed on the product label. What a project costs depends on the subfloor, the removal, the pattern and the room's shape, so an honest number comes from the free in-home measure rather than a chart.

Yes to both. Closets take flooring like any other floor area, so add each one as its own small area. Stairs are figured differently, by tread and riser across the stair width, which the calculator handles when you switch stairs on. Stairs take meaningfully more labor per square foot than open floor.

It is good enough to plan and compare with, and not what we order from. Doorway clearances, transitions, subfloor preparation, plank direction and where seams fall all change a real material list, and none of them are visible to a calculator. The free in-home measure settles those in person, and that measure is the number we order from.

No. The measure and the written estimate are both free and carry no obligation. Call 636-332-0654 or use the form on this page and we will get you on the calendar.
