What Size is a King Duvet? Dimensions and Guide

When choosing a king-size duvet, it’s essential to know its dimensions to ensure it fits your bed and provides optimal comfort. A standard UK king duvet typically measures 225 cm by 220 cm, offering ample coverage for a king-size bed and extra room to stay snug during the night.

This size is designed to drape comfortably over the mattress, helping to minimise drafts and ensuring an even distribution of warmth. Whether you enjoy sprawling out or sharing the bed, a king duvet provides sufficient space and coverage for added cosiness.

Standard King Duvet Dimensions

King duvets come in standard sizes, but these measurements can differ depending on the region. Understanding these differences helps you select a duvet that fits your bed and provides sufficient coverage.

Typical Sizes in the United Kingdom

In the UK, a standard king duvet typically measures 225 cm x 220 cm. This size is designed to fit a king-size bed, ensuring adequate drape and warmth. However, it’s always a good idea to verify the dimensions with the manufacturer, as some variations may occur.

Differences Between UK and European King Duvets

European king-size duvets are often slightly larger than their UK counterparts. They usually measure 240 cm x 220 cm, providing additional width. If you buy bedding from a European retailer, ensure the duvet size matches your bed dimensions to avoid improper fit.

Compatibility with King-Size Beds

A king duvet is specifically designed to fit a standard king-size bed (150 cm x 200 cm). When choosing a duvet, consider how much overhang you prefer. For those who like extra coverage, opting for a duvet slightly larger than the standard size can help eliminate cold spots.

Choosing the Right King Duvet Size

When selecting a king-size duvet, two critical factors to consider are ensuring proper overhang for aesthetics and comfort, and accounting for the dimensions of your mattress, including its depth and overall bed height. These considerations help you achieve an optimal fit both visually and functionally.

Considerations for Duvet Overhang

The overhang of a duvet refers to how much it extends beyond the edges of your mattress. To create a balanced look and prevent cold draughts, your duvet should overhang evenly on all sides of the bed.

For a standard UK king mattress (150 x 200 cm), a typical king duvet measures approximately 225 x 220 cm. This provides sufficient coverage, including an overhang of about 35-40 cm on each side. If you prefer an even more luxurious drape, you might consider sizing up to a super king duvet, depending on your preferences.

Use the following table for quick reference:

Bed Size	Duvet Dimensions	Overhang on Each Side
UK King (150 x 200 cm)	225 x 220 cm	~35-40 cm
Optional: Super King	260 x 220 cm	~55 cm (longer edge)

Ensure your choice matches your desired level of wing coverage while staying appropriate for your bed frame's size.

Impact of Mattress Depth and Bed Height

The depth of your mattress directly impacts how much duvet you need. Thicker mattresses, especially those with pillow tops or memory foam layers, will reduce the fabric available for overhang. If your mattress exceeds a depth of 30 cm, you might need to consider a larger duvet for better fit.

Bed height also matters when choosing a king-size duvet. For taller bed frames, or if you have storage drawers beneath, you may prefer less overhang to prevent the duvet from snagging or interfering with drawer access. Opt for a size that complements both your mattress depth and bed height for a tailored finish.

By balancing mattress depth and bed height, you can ensure your king duvet fits both practically and visually.
