Cut Pile vs. Loop Pile: What's the Difference?

July 24, 2026

If you've spent any time looking at tufted rugs, you've noticed that some are soft and plush while others look tight, nubby and graphic. That's cut pile and loop pile. Understanding the difference is the first thing worth learning, because it shapes every other decision you'll make.

The pile of a rug is its raised surface of fibers, made of upright strands or loops of yarn. It's the part you see and touch. How that surface is created determines its texture, appearance and durability.

What's actually happening

A tufting machine pushes yarn through your primary cloth, forming a loop on the front side. What happens next is the whole difference:

• A loop pile machine leaves that loop alone. It punches through the cloth in a continuous cycle, so the yarn stays as a continuous loop standing up from the cloth.
• A cut pile machine has small mechanical scissors that automatically snip each loop as it's formed. Instead of a loop, you get two cut yarn ends standing up, which bloom outward into a dense, plush, velvety surface.

Same yarn, same cloth, same motion. One tiny mechanical difference gives a completely different result.

Cut pile

Cut pile is the most common style for tufted rugs. Think classic carpet: dense, soft and deep. It's comfortable underfoot and holds up well to foot traffic. Cut pile machines include the AK-I Cut-Pile.

It's forgiving. Because the cut ends splay out and blend into each other, minor inconsistencies in your rows disappear. If your lines wobble slightly or your spacing isn't perfect, cut pile hides it.

It carves beautifully. Once your piece is tufted, you can go in with shears or a carving tool and sculpt the surface. You can sharpen the edges between color blocks or cut depth into the pile to create relief. Most of the dimensional, sculpted rugs you've admired are cut pile.

The trade-off: very fine detail gets fuzzy. Thin lines and small lettering blur into their neighbors.

Loop pile

Loop pile has a nubby, textured, structured look, like a traditional Berber carpet. It's tight and flat, and it holds a crisp edge. If your design has thin lines, tight geometry, text or intricate pattern work, loop pile will render it far more faithfully than cut pile can. Loop pile machines include the AK-II Loop-Pile.

It's durable. The intact loops resist crushing better than cut ends do, and there are no cut ends to snag. That's why so much commercial carpet is loop pile.

The trade-offs:

• Loop pile shows everything. Uneven row spacing, inconsistent speed or a wobble in your line will all be visible. It rewards a steady hand, and it's less pleasant to learn on because your mistakes stay on display.
• Because nothing is cut automatically, you need to cut the yarn by hand when you lift the machine away from the cloth.

Cut + loop

Some machines do both. The DUO, the AK5 and the KRD-I Cut & Loop-Pile can create both cut and loop pile. On the DUO you can switch between sections of a design for texture contrast, or use both at once for a "high-low" sculptural effect. This gives you the most creative flexibility.

Switching your DUO from cut pile to loop pile

You don't need a separate part or attachment to tuft loop pile on the DUO:

1. To create loops, disengage the scissors on the machine.
2. To go back to cut pile, re-engage the scissors.

The small spare part included in your kit is a scissor opener. It's a replacement, only needed if the one on your machine breaks. It is not a loop pile element.

Your user manual and setup videos are emailed automatically when you place your order. They walk through switching modes step by step.

Which should you start with?

Start with cut pile. It's more forgiving while you're building muscle memory, and the results look good sooner. Looking good sooner is what keeps people tufting.

That said, we suggest not locking yourself in. With a machine that does both, like the DUO or the AK5, you can start on cut pile, get comfortable, and then try loop on the same rug when you're curious. That's a better way to learn the difference than reading about it.

Low pile vs. high pile

Pile height is separate from cut vs. loop. It describes how tall the fibers are, and either cut or loop pile can be low or high.

• Low pile (7–18 mm / about .275–.70 in): This is the most common range for rug tufting. The fibers are short and shallow, which is practical for detailed designs, floor rugs and everyday use. Low pile is made with electric tufting machines, including the AK-I Cut-Pile, AK-II Loop-Pile, DUO (low setting), AK5 and KRD-I Cut & Loop-Pile.
• Medium pile (20–30 mm): This gives a fuller texture that's still workable. It's available on the DUO's medium setting.
• High pile (35–60 mm): This gives a shaggy, sculptural, luxurious look. High pile needs more yarn and takes longer to produce. All pneumatic tufting machines (those that need an air compressor) can create high pile. The most elite high-pile machine we sell is the AK-III Industrial Tufting Machine, which handles 20–60 mm. The DUO goes up to 45 mm.

You'll sometimes see everything above low pile, from about 20 to 60 mm (.78–2.36 in), simply called "high pile." To compare machines side by side, see our machine comparison.

Does yarn choice change with pile type?

Somewhat.

• Cut pile is less forgiving of very soft, fine yarns. Soft fibers tend to bend against the scissor blade instead of cutting cleanly, which leaves you with a patchy, half-cut surface. Coarser yarns cut cleanly, which is why wool is the standard.
• Loop pile has fewer constraints because nothing is being cut. Yarn that's too fine will still work its way back out of the cloth, though.

Our rug yarn collection is selected for compatibility with our machines.

The fundamentals stay the same

Whichever pile you choose, the basics don't change:

• Primary tufting cloth stretched drum-tight
• Steady forward pressure
• A consistent pace

Pile type determines the look. Technique determines the quality.
