How Many Yards Is 20 Ft

You're standing in the lumber aisle at Home Depot. The project plans call for 20 feet of pressure-treated 2x6. The boards are sold by the linear yard. The guy next to you mutters something about "six and two-thirds" and you nod like you know exactly what he means.

You don't. Not really.

What Is 20 Feet in Yards

The short answer: 20 feet equals 6.666... Also, yards. That's 6 and 2/3 yards. Or 6 yards and 2 feet. Same thing, three different ways to say it.

The math is stupid simple. But one yard equals three feet. The calculator spits out 6.Always has, always will. So you divide 20 by 3. The fraction people write it as 6 2/3. Still, 66666667. The practical folks say "six yards, two feet.

Here's where it gets useful: most building materials, fabric, fencing, and landscaping products in the US are priced and sold by the yard. But your measurements? Almost always in feet. That disconnect is where mistakes happen.

The Fraction vs. Decimal Trap

6.666... yards looks clean on a calculator. Try ordering 6.666 yards of mulch from a supplier. They'll either round up to 7 (you pay extra) or round down to 6.5 (you come up short). Neither is ideal.

The fraction — 6 2/3 — is more honest. In feet, that's 6 yards (18 feet) plus 2 feet. It tells you exactly what you're dealing with: six full yards plus two-thirds of another. Total: 20 feet. No rounding, no guessing.

Why This Conversion Actually Matters

You might think "I'll just use my phone." Sure. Consider this: until you're on a ladder, tape measure hooked on a rafter, phone in your pocket, and you need to know right now* if that 20-foot board covers the span. Mental math wins on job sites.

Real-World Scenarios Where This Shows Up

Fencing. You're running a 20-foot section between posts. The pre-fab panels come in 6-foot and 8-foot widths. Three 6-foot panels = 18 feet. You're short. Two 8-foot panels = 16 feet. Also short. You need custom cuts or a different layout. Knowing 20 feet = 6 2/3 yards helps you calculate post spacing and material waste before you order.

Fabric and upholstery. That sofa reupholstery project? Fabric comes 54 inches wide (1.5 yards) and sold by the linear yard. Your pattern pieces add up to 20 linear feet of fabric. That's 6 2/3 yards. Order 6.5 and you're scrambling. Order 7 and you've got leftovers — which isn't terrible, actually. Leftovers become throw pillows.

Concrete and gravel. A 20-foot driveway extension, 10 feet wide, 4 inches thick. That's 66.67 cubic feet. Divide by 27 (cubic feet per cubic yard) = 2.47 cubic yards. Order 2.5. The yard conversion just saved you a short load fee.

Landscaping edging. Those plastic paver restraints come in 20-foot coils. The spec sheet says "6.67 yards." You're laying a 60-foot border. Three coils. Done. But if you misread and think each coil is 6 yards? You come up 2 feet short on the last run. That's a second trip to the store.

How the Conversion Works (And How to Do It in Your Head)

The Division Method

20 ÷ 3 = 6 remainder 2.

That's it. 37 feet? Day to day, this works for any feet-to-yards conversion. Six whole yards, two feet left over. 37 ÷ 3 = 12 remainder 1. The remainder is the feet. Twelve yards, one foot.

The Multiplication Check

6 yards × 3 = 18 feet. Plus 2 feet = 20 feet. Checks out.

The Fraction Method

20/3 = 6 2/3. The denominator (3) represents feet per yard. The numerator (20) is your total feet. The whole number (6) is full yards. The fraction numerator (2) is leftover feet.

The Decimal Method (With Caveats)

20 ÷ 3 = 6.666...

If you must* use decimals, carry it to at least three places: 6.67) introduces enough error to matter on large orders. In practice, 33. 5 yards. Across 50 sections, you're off by 2.Even so, 6. 5 yards vs. On top of that, 667. Which means two places (6. 17 yards — about 6 inches — per 20-foot section. Still, that's 0. In practice, 67 × 1000/20 = 333. the true 333.So naturally, on a 1,000-foot fence line? Real money.

Mental Math Shortcuts

• 15 feet = 5 yards exactly. Easy anchor.
• 30 feet = 10 yards exactly. Another anchor.
• 20 feet is 5 feet past 15. So 5 yards + (5÷3) yards = 5 + 1 2/3 = 6 2/3 yards.
• Or: 20 is 10 feet short of 30. 10 yards - (10÷3) yards = 10 - 3 1/3 = 6 2/3 yards.

Pick the anchor that feels natural. Both get you there.

Common Mistakes People Make

Rounding Too Early

"I'll just call it 6.Think about it: " On a $40/yard fabric? On a $120/yard specialty mesh? Here's the thing — that's $10,000. So that's $6. On the flip side, on a 500-yard commercial job? Also, that's $20. 67 difference. 5 yards.Round at the end, not the middle.

Confusing Linear, Square, and Cubic Yards

We're talking about the big one. Linear yards = length only. Now, fabric, fencing, trim, piping. That said, Square yards = area. Worth adding: carpet, sod, concrete slabs. In real terms, Cubic yards = volume. Mulch, gravel, concrete, topsoil.

20 linear feet = 6.Worth adding: 20 square feet = 2. Here's the thing — 67 linear yards. 22 square yards.
Still, 20 cubic feet = 0. 74 cubic yards.

Totally different numbers. I've watched a guy order 20 "yards" of mulch thinking he needed 20 cubic feet. A mountain*. Totally different ordering conversations. He got a mountain. Don't be that guy.

Field‑Ready Shortcuts

When you’re on a job site, you rarely have a calculator handy, but a few mental habits can turn a confusing stack of feet into a clean yard count in seconds.

• Chunk‑and‑count – Break the total feet into groups of three. Every three feet equal one yard, so you simply tally how many complete groups you have and note any leftovers. A 62‑foot run becomes 20 groups of three with a remainder of two feet; that’s 20 ⅔ yards.

• Fraction flash – Remember that the remainder always represents feet, and three feet make a yard. If you have a remainder of 1 foot, you’re ⅓ yard over; 2 feet means ⅔ yard. This instantly tells you whether you need to round up or stay exact.

• Quick‑reference card – A small laminated card that lists the most common anchors (15 ft = 5 yd, 30 ft = 10 yd, 20 ft = 6 ⅔ yd) can be slipped into a pocket or tool belt. Glance at it, do the mental addition, and you’re set.

• Smartphone aid – A one‑tap conversion app eliminates guesswork, but relying on it exclusively can be risky if the device dies or the signal drops. Knowing the underlying math means you can verify the app’s output and avoid a costly misorder.

Beyond Linear Measures

The same principles apply when you move from length to area or volume, though the numbers change.

• Area – One square yard covers nine square feet. If you need to know how many square yards of sod to lay for a 180‑square‑foot patch, divide by nine: 180 ÷ 9 = 20 sq yd.

• Volume – Cubic yards are built from three linear yards. One cubic yard equals 27 cubic feet (3 × 3 × 3). A truckload of mulch quoted as “3 cubic yd” therefore means 81 cu ft.

Understanding these relationships prevents the classic mix‑up where a crew orders 20 linear yd of fencing but actually needs 20 sq yd of fabric, or vice‑versa. That alone is useful.

The Real Cost of a Misstep

A two‑foot shortfall on a 60‑foot edging project may seem trivial, but consider the ripple effect:

• Extra labor – A second trip to the supplier adds loading time, travel distance, and fuel costs.
• Material waste – Ordering a full extra coil means you’ll have leftover material that may become scrap or require special disposal.
• Budget overruns – On high‑price items — specialty mesh, premium edging, or bulk fill — those two missing feet can translate into dozens of dollars, or even hundreds on large commercial jobs.

By internalizing the conversion steps, you eliminate that uncertainty before the first order is placed.

Closing Thoughts

Accurate foot‑to‑yard conversion is more than a classroom exercise; it’s a practical tool that streamlines procurement, reduces waste, and protects profit margins. Whether you’re laying a border, spreading mulch, or ordering fabric for a custom fence, the simple arithmetic — or a quick mental shortcut — ensures you get exactly what you need, the first time. Mastering this skill turns a potential source of error into a reliable foundation for every project you tackle.
