How To Measure Your Floor’s Square Footage

The short version

Multiply the length of the space by its width. That’s your square footage. For a rectangular garage, basement, or patio, that’s the whole calculation — no need to be precise to the inch, a tape measure and a rough number is plenty for an estimate.

Length (ft) × Width (ft) = Square Feet

Example

A two-car garage that’s roughly 22 feet wide and 24 feet deep:

22 × 24 = 528 sq ft

Round to the nearest 10 — call it 530 sq ft. That’s exactly the level of precision our instant estimate is built for.

L-shaped or irregular spaces

Break the space into two or more rectangles, measure each one separately, then add the areas together.

1. Sketch the rough outline of the floor on paper — doesn’t need to be to scale.
2. Draw one straight line across it to split it into rectangular sections.
3. Measure the length and width of each section and calculate its area separately.
4. Add the areas together for your total square footage.

What to do about built-ins

Permanent cabinets, workbenches, or storage built into the slab don’t need to be subtracted for an estimate — we account for obstacles and cutting in around them during the in-person or photo review. Floor area under things that’ll be moved before we arrive (parked vehicles, stored items, portable shelving) should be included in your measurement.

Don’t want to measure it yourself?

That’s completely normal — most people don’t have an exact number and that’s fine. A rough guess (even just "it’s a 2-car garage" or "about the size of a small bedroom") is enough to get started, and we’ll confirm the real number during your visit.
