Quick Answer
You can, but you shouldn't — and the reason is lint, not hygiene. Towels are woven with looped terry pile that sheds continuously; sheets are flat weaves that catch that lint and hold it. Wash them together and your sheets come out fuzzy and pill faster, while the towels stay damp long after the sheets have dried. The three real conflicts are lint transfer, drying-time mismatch, and load imbalance from wet towel weight. If you genuinely have to combine them, use cold water, a low spin, and separate them before drying — the dryer is where most of the damage happens.
Key Takeaways
- Lint is the main problem, and it goes one way. Terry pile sheds onto flat weaves; sheets almost never shed onto towels.
- The dryer does more damage than the wash. Tumbling drives loose pile into the sheet's surface, where it stays.
- Towels hold roughly twice their weight in water. A mixed load leaves either damp towels or over-dried sheets — there is no setting that suits both.
- Percale and linen suffer most. Open, crisp weaves catch lint in a way that smooth sateen partly resists.
- It is not a hygiene issue. Detergent and a normal wash handle bacteria; this is a fabric-damage and efficiency question.
- If you must combine: cold wash, low spin, separate before drying, and never add a new coloured towel to the load.
This question gets asked constantly and answered badly — usually with a vague warning about germs. Bacteria is not the issue. A normal detergent cycle deals with that whether the load is mixed or not.
The real answer is mechanical, and once you see it the rule stops feeling arbitrary. Towels and sheets are built on opposite principles, and putting them in the same drum makes each one worse at its job.
Why towels and sheets fight each other
A towel is engineered to hold water. It uses a looped terry pile — thousands of raised loops that maximise surface area — and that construction sheds fibre every single wash, most heavily in the first ten.
A sheet is engineered to do the opposite: lie flat, feel smooth, and move air. Percale is a tight one-over-one grid; linen is an open plain weave. Both present a surface that catches loose fibre and holds onto it.
Put them together and the transfer only runs in one direction. The towel loses pile, the sheet collects it, and the sheet is the item that shows it.
| Conflict | What happens | Which item loses |
|---|---|---|
| Lint transfer | Terry pile sheds and embeds in flat weave | Sheets — fuzzy surface, faster pilling |
| Drying-time mismatch | Towels hold roughly 2× their weight in water; sheets dry in about half the time | Both — damp towels or heat-damaged sheets |
| Load imbalance | Wet towels clump to one side; light sheets cannot counterweight them | The machine — spin faults, drum wear |
| Abrasion | Heavy wet towels beat against lighter fabric through the cycle | Sheets — accelerated thinning at fold lines |
| Temperature needs | Towels tolerate and often want hotter water than natural-fibre sheets | Sheets — shrinkage and fibre damage if you wash to the towel's setting |
| Tangling | Fitted sheets form a bag and capture towels inside | Both — the contents wash and dry unevenly |
Note what is absent from that table: bacteria. Cross-contamination between your own towels and your own sheets is not a meaningful risk in a domestic machine with detergent.
Open-weave linen — the fabric that shows towel lint fastest, and the one worth protecting from mixed loads.
Which sheets suffer most
The damage is not evenly distributed. How much a mixed load costs you depends almost entirely on what your sheets are made of.
| Sheet fabric | Lint vulnerability | Why |
|---|---|---|
| Linen | Highest | Open plain weave with visible gaps between yarns — lint lodges in the structure, not just on the surface |
| Percale cotton | High | Matte, slightly textured finish gives loose fibre something to grip |
| Flannel | High — and it sheds too | Brushed nap both collects and contributes lint; a mixed flannel-and-towel load is the worst case |
| Cotton sateen | Moderate | The smooth floating-thread surface offers less purchase, so some lint brushes off |
| Microfibre / polyester | Moderate but permanent | Static charge attracts lint and holds it; it also resists coming out in later washes |
| Silk | Low lint, high damage | Smooth enough to resist lint, but far too delicate to share a drum with wet towels at all |
If you own percale or linen — the two weaves most worth owning if you sleep warm — you are in the group with most to lose. Dark sheets make it visible soonest, but pale sheets collect it just as fast.
What a mixed load actually costs
The habit feels efficient because it saves a cycle. Counting what it takes off the other end changes the arithmetic.
Pilling is the mechanism. Embedded lint sits proud of the weave, catches during subsequent washes, and works loose fibres into the small bobbles that make a sheet feel rough. Once a sheet is pilling it does not recover — shaving pills off removes fabric and thins it further.
| Sheets washed separately | Sheets washed with towels | |
|---|---|---|
| Surface after ~30 washes | Smooth; linen visibly softening | Noticeably fuzzy; early pilling on percale |
| Typical replacement point | 5–10 years depending on fabric | Earlier — pilling usually drives replacement before wear does |
| Cycles saved per year | — | Roughly 25–50, at a few pence of electricity each |
| What you trade for it | — | A sheet set that reaches its "I don't like this any more" point sooner |
The honest framing: you are trading a small, certain saving in running costs against an earlier replacement of a far more expensive item. On a cheap sheet set that trade is arguable. On linen or good percale it is not.
The exception worth knowing: old towels shed far less than new ones. Terry pile sheds most in roughly its first ten washes, then settles considerably. A well-used towel and a sateen sheet in a cold wash is a genuinely low-risk combination — a brand-new towel with fresh linen is the worst one.
If you have to combine them: the damage-control version
Small machine, shared laundry, one cycle a week — sometimes separating is not realistic. This is how to do it with the least cost.
- Use old towels only. Never put a new or brightly coloured towel in with sheets. New terry sheds hardest and new dye bleeds.
- Wash cold. Cold water loosens less pile and protects natural-fibre sheets. It also removes the temperature conflict between the two items.
- Drop the spin speed. High spin drives lint into the weave and worsens the imbalance from wet towel weight.
- Do not overfill. A packed drum increases abrasion between heavy towels and lighter sheets. Two-thirds full is the practical limit.
- Separate before drying — this is the important one. Tumbling is where most lint transfer happens. Even if you washed them together, dry them apart.
- Shake sheets out before they go in the dryer or on the line. A firm snap dislodges surface lint before heat sets it.
Step five does most of the work. If you take one thing from this article, it is that the wash is survivable and the dryer is not.
What about sheets with other bedding?
The same logic decides every combination — it is always about weave type and weight, never about hygiene.
| Combination | Verdict | Reason |
|---|---|---|
| Sheets + pillowcases | Yes | Same fabric, same weight, same temperature. The intended load |
| Sheets + duvet cover | Usually yes | Compatible weave; watch capacity, since a duvet cover fills a drum fast and can bag smaller items |
| Sheets + towels | No | Lint, weight and drying time all conflict |
| Sheets + flannel bedding | No | Brushed nap sheds like terry does |
| Sheets + clothing | Generally no | Zips and hooks abrade; sheets bag smaller garments |
| Sheets + blankets | Depends | Fine for a light cotton blanket; wool and weighted blankets need their own cycle entirely |

How to make towels shed less
If lint is the core conflict, reducing it at source helps every load a towel is ever in — not just the mixed ones.
New terry sheds most in roughly its first ten washes as loose pile left over from manufacturing works free. That phase is unavoidable, but you can shorten it and stop making it worse afterwards.
- Wash new towels twice, alone, before first use. This clears the bulk of the loose manufacturing pile in two cycles rather than releasing it gradually across twenty.
- Add half a cup of white vinegar to the first wash. It helps set the dye and strips the silicone finish many towels ship with — the finish that makes them feel plush in the shop and repel water at home.
- Never use fabric softener on towels. It coats the pile, reduces absorbency, and the coating itself breaks down into more lint over time.
- Shake towels out before drying. Same principle as with sheets — remove loose fibre before heat sets it anywhere.
- Clean the lint filter every load. A blocked filter recirculates fibre back into the drum, which is how lint ends up on items that never met a towel.
A well-broken-in towel sheds a small fraction of what a new one does. That is why the mixed-load risk drops sharply with towel age — and why a new towel is the one item that should never share a drum with good sheets.
Percale washed on its own — matte, smooth, and free of the fuzz a shared cycle leaves behind.
The one-load-a-week household
The advice to separate everything assumes unlimited cycles. Plenty of households have a shared machine, a laundrette, or a water bill that makes extra loads a real cost. A rota solves it better than a rule.
| Week | Load | Why it works |
|---|---|---|
| Week 1 | Sheets + pillowcases + duvet cover | One weave family, one temperature, one drying time |
| Week 2 | Towels + bath mats + flannels | Everything sheds, so nothing is damaged by it |
| Week 3 | Sheets + pillowcases | Back to the bed; swap in the second set while this washes |
| Week 4 | Towels + any flannel bedding | Group the nap fabrics together, away from flat weaves |
This keeps the weekly cycle count identical while never putting a shedder and a catcher in the same drum. It works because sheets and towels do not actually need washing on the same schedule — sheets benefit from weekly, towels are usually fine every three to four uses.
The enabling detail is owning two sheet sets. Rotating them means a bed can be stripped and remade immediately, the wash can wait for its slot in the rota, and both sets last roughly twice as long as a single set would — which pays for the second set several times over.
Five mistakes people make with mixed laundry
- Assuming the concern is germs. It isn't, and treating it as a hygiene question leads people to wash hotter — which damages natural-fibre sheets without solving the actual problem.
- Washing separately, then drying together. This undoes the entire benefit. The dryer is where lint embeds.
- Adding a brand-new towel to any load. New terry sheds hardest in its first ten washes, and new dye is least stable then too.
- Using fabric softener to "fix" fuzzy sheets. It coats the fibres, blocks absorbency, and makes towels less absorbent at the same time. It masks the symptom and adds a second problem.
- Overloading to save a cycle. A packed drum increases abrasion and stops either item rinsing properly, so you get lint and detergent residue.
Frequently asked questions
Can you wash sheets and towels together?
Physically yes, but it costs you. Towels shed terry pile that embeds in the flat weave of sheets, causing fuzziness and early pilling, and the two need different drying times. It is a fabric-damage issue rather than a hygiene one.
Is it unsanitary to wash towels and sheets together?
No. In a domestic machine with detergent, washing your own towels with your own sheets poses no meaningful hygiene risk. The reasons to separate them are lint, drying time and load balance.
What should you not wash with towels?
Anything with a flat or delicate weave — bed sheets, duvet covers, silk, activewear and anything with hooks or zips. Towels are best washed with other towels, which shed onto each other harmlessly.
What laundry should not be washed together?
Keep four things apart: lint shedders from lint catchers (towels vs sheets), heavy wet items from light ones, hot-wash items from delicate natural fibres, and anything with hardware from smooth fabric it can snag.
Why do my sheets feel fuzzy after washing?
Almost always towel lint embedded in the weave, usually driven in by tumble drying. Once it has been heat-set it is very difficult to remove, and it accelerates pilling from then on.
Does washing sheets with towels cause pilling?
It is a major contributor. Embedded lint sits proud of the surface, catches in later washes, and works fibres loose into bobbles. Pilling is not reversible — removing pills removes fabric.
Can I wash sheets and towels together in cold water?
Cold water is the best-case version of a bad idea — less pile is released and natural fibres are protected. Do it if you must, drop the spin speed, and still separate them before drying.
Can you dry sheets and towels together?
This is the one to avoid most. Tumbling drives loose pile into the sheet's surface where heat sets it, and the mismatch in drying time means over-drying the sheets or under-drying the towels.
Can you wash sheets and pillowcases together?
Yes — same fabric, same weight, same temperature. Sheets and pillowcases are the load these settings are designed for, and a duvet cover can usually join them if the drum has room.
How do I get towel lint off my sheets?
Rewash alone with half a cup of white vinegar in the rinse, then line dry and shake firmly. This lifts surface lint. Fibre already heat-set into the weave will not come out, which is why prevention matters more than removal.
