Free laundry tool

Duvet & comforter fit checker

Check duvet permissions, measured dry weight, programme limits and room to move.

Free · No account needed Method & sources

Before you start

Your bedding care label, washer manual and, if possible, the item’s dry weight.

What you’ll get

A fit assessment with the checks passed, details still missing and your next step.

A size name or kg rating alone cannot confirm that bulky bedding fits.

Your bedding

A few details about the item you want to wash.

230 × 220 cm (90.6 × 86.6 in)Reference dimensions vary by brand. Measure your actual item.
Exact product and removable cover

Dimensions describe your item; they cannot prove it fits a drum. A removable cover may have different care instructions. If checking only the cover, select Bedding type: cover.

Add dry weight or tog
Weighed dry, without its cover unless washed together.
Thermal insulation only. Not converted into weight or volume.

How this tool works

Checks label permission, machine permission, measured dry weight against entered limits, and physical fit. Unknown checks remain unknown. Tog and drum volume are never converted to kg.

The numerical limits on form fields are validation bounds, not recommended appliance settings. Missing data is not permission to proceed.

Using this tool

Check duvet fit using the finished care label, the exact washer’s instructions, the dry item’s weight and its physical loading arrangement. The checker combines these conditions and identifies what still needs confirmation. A king label, tog value or headline machine capacity cannot answer the fit question alone.

How to check whether a duvet fits your washer

Have the filled item’s label and the manual for the exact machine available. Select known permissions and use a measured dry weight where possible. Assess room to move according to the loading instructions rather than simply whether the door closes. Unknown details should remain unknown.

Samsung’s loading and cycle guidance explains separate space and programme checks. A general article is not a specification for every model.

Understand a conditional fit result

For an illustrative comparison, a 2.6 kg dry duvet exceeds a confirmed 2 kg programme limit, even in an 8 kg washer. A 1.7 kg duvet is below that example limit but still needs washing permission and physical room. Missing the programme limit leaves the comparison unresolved.

Use the result to identify a next step, such as locating the manual or asking the maker about construction. The tool cannot inspect your drum or certify a product.

Common questions

Can this tool guarantee my duvet is safe to wash?

No. It evaluates the checks you enter and shows missing information. The item’s instructions and exact appliance manual remain the authority.

Does the checker turn tog into kilograms?

No. Tog measures insulation. Enter a measured dry weight or leave that check unresolved.

Can I share my fit result?

The share link includes selected non-sensitive inputs, excluding optional manufacturer/model text. Anyone with the link can read its parameters.
