How to figure out your home’s square footage Measure the length and width of each room. Multiply the length by the width to calculate the total square footage of the room. Add up all of the rooms to calculate your home’s total square footage.

Countertop

Measure each section and record the length and depth dimensions of the sections (in inches, rounded to the nearest inch). Add all the sections together to find the total square inches. Divide the total square inches by 144 to get the total square feet.

Fence

Multiply the height by the length then by two (for both sides) to find the total square feet.

Example 5ft high X 100 ft long X 2 sides = 1000 sq ft

In-ground pool

How to measure total square footage for painting or lining:

(Length x Width) + (Length x Avg Depth x 2) + (Width x shallow depth) + (Width x deep depth) = Total square footage of surface area of all the pool sides and bottom.

To determine average depth in a pool where the bottom slopes: Measure the shallow end and measure the deep end. Add them together and divide by 2. This is the average depth of your pool.

Below is an example using a 18 x 34 pool with a Shallow depth of 4′, a deep depth of 8′ and an average depth of 6′ feet

L x W = (34 x 18) = 612

L x Avg. Depth x 2 = (34 x 6 x 2) = 408

W x Shallow Depth = (18 x 4) = 72

W x Deep Depth = (18 x 8) = 144

612 sq ft for the bottom + 408 sq ft (the two long sides) + 72 sq ft  (small side) + 144 sq ft (deep side) = 1236 total sq ft

How much space needed to install an outdoor pool:

 Pool dimensions Minimum space required Comfortable amount of space 40′ x 20′ 52′ x 30′ 60′ x 45′ 36′ x 18′ 48′ x 28′ 56′ x 40′ 30′ x 15′ 42′ x 25′ 44′ x 26′ 28′ x 14′ 36′ x 24′ 38′ x 26′ 24′ x 12′ 34′ x 22′ 38′ x 26′ 20′ x 12′ 32′ x 22′ 34′ x 24′ Endless pool 14′ x 7′ 24′ x 14′ 24′ x 14′

Roofing

Measure the length and width of each section of roofing. Multiply length by width to get the square footage of each section. Add the square footage of each of the sections together. Multiply your total square footage by your roof’s slope.

Calculate the slope of your roof using our guide for pitch factors below (the average pitch roof is 6/12 with a pitch factor of 1.12)

Remember to include 10-12% for waste.

(Total sq footage) x (pitch factor) x (waste) = Roof size

For example,

If the roof length is 20 ft, the roof width is 25 ft, and pitch is 6/12 then

20 x 25 = 500 sq ft

500 x 1.12 = 560 sq ft

560 x 12% = 627 sq ft

Round your results to the nearest hundred (700 sq ft)

Square feet are often referred to as squares: 700 sq feet = 7 squares

 Pitch Factor 1/12 (no slope) 1.01 2/12 1.02 3/12 1.03 4/12 1.05 5/12 1.08 6/12 (average slope) 1.12 7/12 1.16 8/12 1.20 9/12 1.25 10/12 1.30 11/12 1.36 12/12 (vertical) 1.41

Home sizes

Small homes typically are less than 1,000 square feet

Average homes are around 2,500 square feet

Big homes are 4,000 square feet or larger

\$120-\$200 per square foot of house on average

Walk-in closet

The standard width of a walk in closet can range from 5 to 12 feet or more. The standard depth of a walk in closet can range from 5 feet (for a square room) to 17 feet (or more for a large closet)

The National Association of Home Builders states that this is how much you space you should allot for each room:

• Master bedroom – 300 square feet
• Other average bedrooms – 432 square feet
• Master bathroom – 154 square feet
• Kitchen – 300 square feet
• Dining room – 192 square feet
• Family room – 296 square feet
• Living room – 223 square feet
