How often to wash sheets, according to the people who make them
Every seven days to once a fortnight, and the people who make sheets do not agree with each other. We read six care pages published by sheet makers and one retailer. Five give a figure, the figures differ, and the sixth publishes no frequency at all.
The number is the least interesting part of the answer. What the same pages agree on is that washing has a cost, and that the cost depends on the fibre: Parachute writes that frequent washing breaks down cotton fibres, and every linen source we read says the opposite about linen, that it improves with each wash.
The sharpest evidence is that one publisher gives two different answers for its own two fabrics. So the honest answer to how often you should wash sheets is that it is a question about your cloth, not a rule.
One thing we are not doing here, and it is worth saying at the top rather than burying it. The pages that rank for this question answer it from hygiene. We are not answering the hygiene question.
We are a bedding research desk and not a health authority, so we report what the manufacturers publish about their own fabric and leave the rest to people qualified to speak on it.
What the makers actually publish
Rather than repeat the figure everybody repeats, we went to the care pages of the companies that make and sell the sheets, and read what each one tells its own customers. Six pages, read on 12 August 2026, named here in text rather than linked. Five of the six publish a frequency and no two of those five say quite the same thing.
| Who publishes it | What they sell | How often they say | What they say washing does to the fibre |
|---|---|---|---|
| Parachute, percale care page | Its own cotton sheets | Every seven to 10 days | Says frequent washing breaks down cotton fibres |
| Parachute, linen care page | Its own linen sheets | Once a week | Says linen gets better every time it goes through the wash |
| Scooms | Its own linen bedding | Every seven to 10 days | Says the texture improves with each wash, and warns that over-drying can weaken the fibres |
| Piglet in Bed | Its own linen bedding | Once or twice a fortnight | Says linen gets softer with every wash |
| Fine Linen and Bath | A retailer, selling other brands | Every one to two weeks | Gives one figure for all fabrics and draws no distinction between them |
| Thomas Lee | Its own cotton sheets | No frequency published at all | Method only: says high heat cooks the fibres and chlorine bleach weakens cotton |
The RestVerdict comparison of published washing frequencies, read from six care pages on 12 August 2026. Parachute's linen page names a single figure, once a week. Parachute's percale page and Scooms both give seven to 10 days. Piglet in Bed gives once or twice a fortnight and the retailer Fine Linen and Bath gives one to two weeks for every fabric it sells.
Thomas Lee appears on no part of the scale, because it publishes only a method and never says how often. The spread is the finding: this is not a question with a settled answer, and the tidy figure repeated everywhere is not one the manufacturers agree on.
One brand, two fabrics, two answers
Comparing rival companies proves little on its own, since they could simply disagree. The stronger case comes from a single publisher. Parachute keeps separate care pages for its percale and for its linen, and the two pages differ in both directions at once.
- On its cotton percale it sets the rule at every seven to 10 days, and states that frequent washing breaks down cotton fibres.
- On its linen it sets the rule at once a week, and states that linen gets better every time it goes through the wash.
One company, two fabrics, a shorter interval for the fabric it says improves with washing and a longer one for the fabric it says washing degrades. Whatever else that is, it is not a company applying a house rule.
It is a company describing two different materials, which is the whole answer to the question this page asks. The other linen makers we read line up with it: Scooms says the texture improves with each wash, and Piglet in Bed says linen gets softer with every wash.
What none of them publish
Two absences are worth stating, because a gap you can name is more useful than a number you cannot check.
- Nobody explains where their figure comes from. Not one of the six pages we read shows a test, a measurement or a source behind its interval. They are house recommendations, and we report them as house recommendations rather than as findings.
- The retailer is the one that generalises. Fine Linen and Bath sells other companies' brands and gives a single figure, one to two weeks, for every fabric on its shelves. The makers of a specific cloth wrote fabric-specific guidance; the shop selling many cloths wrote one line for all of them. That is worth noticing when you meet a universal rule anywhere else.
We are also not adding a seventh figure. We have run no test that would entitle us to one, and an invented number presented with confidence is the exact failure this page was written to point out.
Where this page stops
There is a neighbouring question this page deliberately does not take over. How cotton and linen behave over months of ownership, why linen arrives at its worst and improves while cotton arrives at its best and slowly thins, and which of the two you should buy, all belong to our linen against cotton guide, which is built on that comparison.
This page is about one narrower thing: what the manufacturers publish about how often to run the wash, and the fact that they disagree.
Two other boundaries, so the section reads consistently with the rest of the site. Weave is a separate property from fibre and does not change the frequency answer.
If the words on your packet are unclear, our guide to what percale actually means separates the weave from the fibre, and the cotton fibre claims guide covers reading what a sheet is really made of.
And a stain is not a schedule: getting to a mark quickly has nothing to do with the wash interval, which is why getting blood out of sheets is its own guide with its own rule.
What costs a sheet more than washing
The same care pages are far more emphatic about heat and chemistry than about frequency, which is itself informative. Everything in this list is what a named publisher tells its own customers.
- Heat in the dryer. Thomas Lee says high heat will cook the fibres and cost the sheet its softness. Parachute asks for low heat and for the sheets to come out slightly damp rather than bone dry. Scooms warns specifically against over-drying, saying it can weaken the natural fibres.
- Chlorine bleach. Thomas Lee says never to use it and that it weakens cotton fibres. Parachute says the same, that bleach weakens cotton fibres in the long run.
- Fabric softener. Parachute says it puts extra strain on the fibres over time. Thomas Lee says never to use it. Scooms says not to use it either.
- Too much detergent. Thomas Lee asks for a quarter to a third of the recommended amount and says excess leaves sheets feeling scratchy. Parachute asks for half the amount the detergent maker recommends. Both are asking for less than the bottle says.
Read together with the frequency question, that is a useful reordering. The interval between washes is the thing most articles argue about, and it is the thing the manufacturers write least about. How you run the wash is what their pages are actually full of.
The same pattern holds elsewhere in the bedding cupboard: our guide to washing a mattress protector found the manufacturers similarly detailed about method and similarly silent about frequency, and there the silence mattered even more.
Common questions
How often should you wash sheets?
The makers do not agree, publishing anything from every seven days to once a fortnight. Parachute says seven to 10 days for its cotton and once a week for its linen; Scooms seven to 10 days; Piglet in Bed once or twice a fortnight; the retailer Fine Linen and Bath one to two weeks; Thomas Lee no frequency at all. We add no seventh figure: we have tested nothing.
Does washing sheets more often wear them out?
It depends on the fibre. Parachute states that frequent washing breaks down cotton fibres. The linen sources say the opposite: Parachute writes that linen gets better every time it is washed, Scooms that its texture improves with each wash, and Piglet in Bed that it gets softer with every wash. So an extra wash costs cotton something, and is not described as a cost for linen at all.
Why does the same brand give two different answers?
Because it sells two different fibres. Parachute publishes separate care pages for its percale and its linen, and they carry different figures and opposite statements about what washing does to the cloth. That is the clearest evidence on this page that the answer belongs to the fabric rather than to a general rule, since it comes from one publisher rather than from us comparing rival brands.
Is once a week enough?
It sits inside the range every source we read publishes, and two of them name exactly that figure. What we will not tell you is whether it is enough for hygiene, because that is a health question and we are a bedding research desk. This page reports what the people who manufacture sheets publish about their own cloth, and that is a different question with a documented answer.
What shortens the life of a sheet more than washing does?
Heat and chemistry, going by the same care pages. Thomas Lee says high heat cooks the fibres and that chlorine bleach weakens cotton. Parachute says bleach weakens cotton fibres in the long run and fabric softener strains them. Scooms warns that over-drying can weaken the natural fibres. Several also ask for far less detergent than the bottle suggests: a quarter to a third for Thomas Lee, half for Parachute.
