What is kitchen square footage?

Kitchen square footage is the total floor area of a kitchen measured in square feet. A standard kitchen is 100-200 sq ft (9.3-18.6 m²). A large open kitchen with island runs 250-400 sq ft (23.2-37.2 m²).

1 ft² = 144 in² 1 ft 1 ft (12 in)

Getting started

How to Calculate Kitchen Square Footage

To calculate kitchen square footage, measure length and width of the kitchen floor in feet, then multiply length × width. A 10 × 12 ft (3.05 × 3.66 m) kitchen equals 120 sq ft (11.15 m²). Subtract permanent island bases from floor area for tile or vinyl orders.

1. Measure floor area

Measure kitchen length and width in feet. Subtract island bases and permanent appliance footprints.

2. Plan layout zones

Use the area to plan cabinet runs, countertops, and the work triangle (sink, fridge, stove).

3. Estimate flooring or tile

Order kitchen flooring with a 10% waste factor for cuts around cabinets and appliances.

20 ft 15 ft 300 ft² Area: 300 ft² Order: 330 ft² +10% waste factor included

Quick reference

Reference

1 acre = 43,560 square feet
1 square yard = 9 square feet
1 square meter = 10.764 square feet
1 square inch = 0.00064516 square feet
Area: 300 ft² × Price: $2.80 / sq ft Total: $840.00 estimated material cost

Material pricing

Calculate Cost of Materials

Kitchen flooring costs $5-15 per sq ft installed. Backsplash tile costs $15-40 per sq ft installed. Multiply kitchen area by price per unit for total cost.

There are 2 steps to calculate material cost:

  1. Enter the price per square foot of tile, vinyl, hardwood, or laminate. For backsplash, calculate wall area separately.
  2. The Square Foot Calculator multiplies kitchen area by the price to give a material total. Add labor and grout separately.

A 120 sq ft kitchen with mid-range tile costs $1,800-3,000 for materials. Add 10-15% extra tile for cuts and breakage.

FAQ

Frequently Asked Questions

How many square feet is an average kitchen?

The average kitchen is 100-200 square feet. Small kitchens are around 70-100 sq ft, medium kitchens 100-200 sq ft, and large kitchens 200+ sq ft.

How do I calculate kitchen flooring needs?

Measure kitchen length and width, multiply for square footage, then add 10% for waste. Include the area under cabinets and appliances even if they cover the floor.

How many square feet is a 10x12 kitchen?

A 10x12 kitchen is 120 square feet (10 ft x 12 ft = 120 sq ft). This is a typical medium-sized kitchen.

Should I include the island in kitchen square footage?

Yes, the floor area under a kitchen island is included in total kitchen square footage. The island sits on top of the floor and doesn't reduce the room's area.

How do I calculate tile for a kitchen backsplash?

Measure the width and height of the backsplash area, multiply for square footage, and add 10% for waste. Subtract any windows or outlets from the total area.

What is a good kitchen size for a home?

A functional kitchen is at least 70 square feet, with 150-200 square feet being ideal for most families. The kitchen-to-house ratio is typically 10-15% of total home square footage.
