What Does Low Pile Mean, and Should You Want It?

Pile height is the length of the yarn standing up from the backing. It changes far more about living with a rug than how it looks.

The rough categories

• Flatweave — no pile at all. Kilims and rag rugs.
• Low pile — under about 6 mm.
• Medium — 6 to 13 mm, most tufted rugs.
• High or shag — above 20 mm.

What low pile changes

• Doors clear it. A medium or high pile rug in a doorway means planing the door.
• Dining chairs slide instead of catching, which is the single biggest argument for low pile under a table.
• Robot vacuums pass over it rather than beaching on it.
• It vacuums properly — grit cannot bury itself out of reach.
• It dries in hours rather than a day, which is what makes washing practical.

What you give up

Underfoot softness and acoustic absorption. A deep pile rug in a hard-surfaced room noticeably quietens it; a low pile does much less. If a room echoes, pile height is the lever.

Where each belongs

Low pile for halls, kitchens, dining rooms, under doors and anywhere with wheels. Deeper pile for bedrooms and sitting rooms where the floor is for standing on barefoot rather than walking through.
