Determining how much outdoor carpet you need for a specific area can seem daunting, but it’s actually quite simple with some basic calculations. Here’s a step-by-step guide to figuring out the square footage of outdoor carpet you’ll need for any space.
Measure the Length and Width of the Area
The first step is to measure the length and width of the area you want to cover in feet. For irregular shapes, break the area down into rectangles and triangles to get accurate measurements.
For example, let’s say the area you want to carpet is a 12 ft by 15 ft rectangle.
To find the total square footage:
Length x Width = Square Footage
So in this case:
12 ft x 15 ft = 180 sq ft
Be sure to write down the measurements and calculations. You’ll need them in the next step.
Calculate the Total Square Footage
Now calculate the total square footage by adding together the square footage of each measured section.
For our example 12 x 15 space:
Total square footage = 180 sq ft
Round up to the nearest whole number after adding all sections together. Having a bit extra is better than not having enough carpet.
Factor in Seam and Edge Allowances
Once you have the total square footage, you need to add in some extra for seam and edge allowances.
- For seam allowances, add 2 inches of carpet for every seam you expect to have.
- For edge allowances, add 3-5 inches around the perimeter.
This ensures you have enough carpet to secure the edges and seams properly during installation.
For our 180 sq ft space, let’s say we need 1 seam allowance of 2 inches or 0.17 ft. And we’ll do a 4 inch or 0.33 ft edge allowance.
180 sq ft
- 0.17 ft (1 seam allowance)
- 0.33 ft (edge allowance)
= 180.5 sq ft
Round up to 181 sq ft.
Order 10% Extra as a Safety Net
It’s always smart to order 10% more outdoor carpet than your total square footage calculation. This provides insurance in case you measured incorrectly or need to replace sections later on.
For our original 180 sq ft space, we calculated we need 181 sq ft with allowances. Add 10%:
181 sq ft
x 0.10 (10%)
= 18.1 extra sq ft
So for our example space, you would want to order approximately 200 sq ft (181 + 18.1) of outdoor carpet to have plenty of extra material on hand.
Summary
To determine how much outdoor carpet you need:
- Measure length x width in feet for each section
- Add together for total square footage
- Add allowances for seams and edges
- Add 10% as a safety net
- Order that total square footage amount
Having the right outdoor carpet measurements ensures you get the perfect amount for full coverage without gaps or seams showing. So take the time to carefully measure and calculate before purchasing materials. Let us know if you have any other questions!
Frequently Asked Questions
How much extra should I order for seam and edge allowances?
- For seam allowances, add 2 inches of carpet for every seam you expect to have.
- For edge allowances, add 3-5 inches around the perimeter.
What’s the best way to get accurate measurements?
Break up irregular shapes into rectangles and triangles. Measure length x width for each section in feet, then add together for total square footage. Use a laser measuring device or tape measure for precision.
Should I go bigger or smaller with my square footage calculation?
It’s better to have too much than not enough. Round up during calculations, and add 10% extra as a safety net. You can always save leftovers.
What if I measured wrong or ordered the wrong amount?
Having that extra 10% helps avoid problems, but if you’re drastically short you may need to order more. Be sure to save receipts and order numbers in case you need to return or exchange carpet.
How much does outdoor carpet cost?
Outdoor carpet costs $2-$6 per square foot on average depending on material, quality, and size. Synthetic options are cheaper than natural fiber. Include seams, edges, waste, and other installation supplies in your budget.
What tools do I need to install outdoor carpet?
You’ll need a utility knife, knee kicker, seam iron, seam tape, hammer, staple gun, broom, and outdoor carpet adhesive. Nail down any edges or seams for security. Watch tutorials to ensure proper installation.
