A buyer's guide from Carolyn Fabrics — High Point, NC
Leather is not sold like fabric. Fabric comes off a roll in a consistent width, so you order yards. Leather comes as full hides—natural, irregular shapes with no two exactly alike—so a pattern that calls for “6 yards of 54-inch material” must be converted into full hides before ordering.
The short answer
The upholstery trade uses a working rule of thumb of about 18 square feet of hide per yard of 54-inch-wide fabric. That planning allowance accounts for cutting rectangular pattern pieces from an irregular hide and working around natural edges, marks, and grain variation.
To estimate the number of hides:
- Take the 54-inch fabric yardage required by the pattern.
- Multiply that yardage by 18 to estimate the square feet of hide required.
- Divide by the stated average size of the leather you are buying.
- Round the result up to the next full hide.
Slipstream Aviation Leather averages approximately 50–55 square feet per full hide. Using 52 square feet as a planning figure, one Slipstream hide replaces roughly 2.5 to 3 yards of 54-inch fabric. Actual usable yield depends on the hide and the pattern layout.
Why use 18 square feet per yard?
On paper, one yard of 54-inch fabric contains 13.5 square feet. A hide is not a rectangle: it includes a neck, legs, belly, natural edges, and grain variation. The 18-square-foot rule builds in a practical cutting allowance for typical seating work. Tight patterns with many small pieces may use a hide differently from long, simple panels.
The formula is a planning tool, not a guarantee. Lay out the actual pattern pieces before cutting whenever the job is close to a full-hide boundary.
Worked examples
A pair of dining chairs: 4 yards × 18 = 72 square feet. At approximately 52 square feet per hide, 72 ÷ 52 ≈ 1.4. Round up and order 2 full hides.
A restaurant booth run: 6 yards × 18 = 108 square feet. At approximately 52 square feet per hide, 108 ÷ 52 ≈ 2.1. Round up and order 3 full hides.
A single accent chair: 2.5 yards × 18 = 45 square feet. That plans below one average hide, so order 1 full hide.
Aircraft seats: If the pattern estimate is 5 yards, 5 × 18 = 90 square feet. At approximately 52 square feet per Slipstream hide, 90 ÷ 52 ≈ 1.7. Round up and order 2 full hides. Confirm material, color, production-order, and documentation requirements with the person responsible for the specific aircraft and installation before ordering or cutting.
Why rounding up usually costs less
- Dye lots: natural leather can vary between production orders. Buying the required quantity together gives the best chance of consistent color.
- Cutting allowance: pattern placement, natural marks, directional grain, and mistakes can reduce usable yield.
- Future repairs: leftover leather from the original order is the best source for a close-match repair.
- Final sale: full hides are natural, one-of-a-kind goods and are final sale, so confirm color and quantity before ordering.

Quick reference table
| Fabric yardage (54 inches) | Estimated hide area | Full hides to order (using 52 sq. ft. each) |
|---|---|---|
| 1 yard | 18 sq. ft. | 1 hide |
| 2 yards | 36 sq. ft. | 1 hide |
| 3 yards | 54 sq. ft. | 2 hides |
| 4 yards | 72 sq. ft. | 2 hides |
| 5 yards | 90 sq. ft. | 2 hides |
| 6 yards | 108 sq. ft. | 3 hides |
| 8 yards | 144 sq. ft. | 3 hides |
| 10 yards | 180 sq. ft. | 4 hides |
Always round up to a full hide. Recheck the calculation when color match matters, when the pattern has many small pieces, or when you want repair stock.
Frequently asked questions
How many yards of fabric does one hide replace?
A 50–55 square-foot hide replaces roughly 2.5 to 3 yards of 54-inch fabric using the upholstery trade's 18-square-foot planning rule. Confirm the actual average hide size on the product page before calculating.
Why is the planning allowance 18 square feet when a yard is only 13.5 square feet?
A hide is not rectangular. The higher planning figure allows for natural edges, pattern placement, marks, and grain variation.
Should I round up or down?
Round up to the next full hide. Carolyn Fabrics sells leather by the full hide only; fractional hides are not available.
How do I convert six yards of fabric into hides?
Six yards × 18 = 108 square feet. Using a 52-square-foot planning size, 108 ÷ 52 ≈ 2.1, so order 3 full hides.
What aviation documentation comes with Slipstream?
Each shipped Slipstream full hide includes Carolyn Fabrics-branded manufacturer production-order material-test documentation matched to the shipped color and dye lot. The record reports the leather material's FAR 25.853 12-second vertical test results. It is material evidence, not FAA approval of an aircraft, seat, or finished installation.
Can I return a hide if I order too many?
No. Full hides are natural, one-of-a-kind goods and are final sale. Confirm color with a $5 selected-color swatch or the $25 Slipstream sample deck, and call us if you want help reviewing the yardage calculation before ordering.
