King Duvet Covers

King duvet covers engineered for a real king mattress — 100% long-staple cotton at 300 thread count percale, 160 gsm, with 8 interior attachment points (4 corner ties + 4 mid-side loops) and a concealed coconut-shell button placket. Our king duvet covers are pre-shrunk and garment-washed so the fit stays true after 100+ machine washes.

King duvet covers built for a real king mattress

A king-size bed demands coverage that matches its footprint. Too many duvet covers marketed as “king” leave you tugging fabric to one side at 2 a.m., so we engineered our king duvet covers with generous drop on three sides and eight interior attachment points — four corner ties and four mid-side loops — to anchor your insert exactly where it belongs.

Construction that earns its place on your bed

The shell is woven from 100% long-staple cotton in a crisp 300-thread-count percale weave, finished with reinforced double-stitched French seams along every edge. A concealed coconut-shell button placket at the foot keeps the closure flat and snag-free — no exposed zippers catching on your sheets, no cheap plastic hardware.

Why king-size shoppers come back to these king duvet covers

Whether you’re fitting a standard king (76 × 80 in.) or stepping up to an oversized king mattress, the proportions hold. The extra drape — roughly 12 inches of drop per side — keeps the look hotel-taut rather than pulled thin, and the 160 gsm fabric weight sits heavy enough to stay put without feeling stiff. Pre-shrunk and garment-washed at the mill, the fit stays true after 100+ machine washes.

King duvet covers size guide

Works with the insert you already own

Slip your existing down, down-alternative, or wool duvet insert inside our king duvet covers and fasten the corner ties. The opening is wide enough to stuff a king insert without a wrestling match, then the button placket seals it shut. If you’re replacing a king comforter with a duvet system for the first time, this cover converts any comforter into a protected, washable setup — just button it in, wash the cover when needed, and skip the dry-cleaner trips.

How to care for your king duvet covers

• Machine-wash cold on a gentle cycle
• Tumble-dry low
• The fabric is pre-shrunk and OEKO-TEX Standard 100 certified — free from harmful substances wash after wash
• Iron warm if a crisp finish is preferred
• Skip fabric softener — dulls the percale hand
• No dry-cleaning required

Frequently asked questions

What size are king duvet covers?

Our king duvet covers are 104 × 90 in. — proportional drop on a standard 76 × 80 in. king mattress. For Cal king, choose California King Duvet Covers instead.

Do king duvet covers fit oversized king mattresses?

They fit standard king and oversized king within a couple of inches of the 76 × 80 baseline. For distinctly larger sizes (Alaskan king, Wyoming king), those need dedicated cuts.

Are king duvet covers the same as Cal king duvet covers?

No. Standard king is 76 × 80 in.; Cal king is 72 × 84 in. — narrower and longer. The covers are cut differently and are not interchangeable.

Do king duvet covers have zippers?

Ours use a concealed coconut-shell button placket at the foot rather than a zipper — flat, snag-free, and durable.
