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.
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.
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
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′|
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
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
|1/12 (no slope)||1.01|
|6/12 (average slope)||1.12|
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
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
