Floor Plan Measurement for Flooring
Ordering flooring short means a delay and a dye-lot mismatch. Ordering too much wastes money. Getting the square footage right from your floor plan before you order is the fix.
What to measure for flooring
For flooring, measure the full room footprint including under permanent cabinets (kitchen island, built-in cabinets, and vanities that will stay in place). Flooring runs under fixed cabinets in most installations. The exception is when you are doing a kitchen remodel where the cabinets are being replaced: in that case, you only need to cover the floor area the cabinets do not sit on, plus transition areas.
For closets, measure and include them. Closet flooring is often overlooked until installation day.
How to measure from a floor plan
- Upload your floor plan to MeasureFloorPlan.com.
- Trace the room or rooms being floored as separate polygons. For an open-plan living/dining/kitchen, trace the entire connected area as one polygon if the floor runs continuously through it.
- Include closets in the room traces (or add them as separate small polygons).
- Set scale from any labeled room dimension.
- Read the total area per room and overall total.
- Apply the appropriate waste factor (see below) to get your order quantity.
Waste factors by flooring type
| Flooring type | Straight lay | Diagonal / herringbone |
|---|---|---|
| Hardwood (solid or engineered) | 7-10% | 12-15% |
| LVP / LVT | 7-10% | 12-15% |
| Ceramic or porcelain tile | 10% | 15% |
| Natural stone tile | 10-15% | 15-20% |
| Carpet (sold by sq yd) | 10% | 10% |
| Laminate | 10% | 15% |
Waste factors account for cuts at walls, doorways, and irregular room shapes. For rooms with many angles or obstacles, add an extra 2-3% beyond the standard waste factor.
Carpet is sold differently
Carpet is sold by the square yard (1 sq yd = 9 sq ft), and comes in rolls that are typically 12 feet wide. The amount you order depends on how the carpet can be seamed across your room layout: it is not always a simple area calculation. Get your square footage from the floor plan, then share the room dimensions with the carpet supplier. They will calculate the roll cuts and minimize seams for you.

How do I calculate flooring square footage from a floor plan?
Trace each room you plan to floor as a separate polygon, set scale once, and the tool returns the area for each room and the total. Then apply your waste factor (10 percent for hardwood, 15 percent for diagonal patterns or tile) to get the order quantity.
What waste factor should I add?
Standard waste factors: 10 percent for straight-lay hardwood, LVP, and laminate; 15 percent for diagonal patterns or tile in irregular rooms; 20 percent for natural stone, herringbone, or rooms with many cuts. Always order at least one extra box for future repairs.
Should I include closets and hallways?
Yes. Anything you plan to install flooring in needs to be in the total. Trace each closet, hall, and transition area as part of the room or as separate small polygons. Forgetting them is the most common reason orders run short.
How accurate does the floor plan need to be?
Within 2 to 3 percent is fine for ordering, since the waste factor absorbs more variance than that. The bigger risk is missing a room entirely, not minor scale imprecision.
Can I get an estimate without a labeled floor plan?
If no dimensions are labeled, use a known reference (a 32-inch interior door, a 36-inch exterior door) to set scale. The result is less precise but still within the typical waste factor margin.
