Why Finding the Right Cot Size Fitted Sheet Matters
A cot size fitted sheet typically measures 30" x 75" and is designed to fit narrow twin mattresses commonly found in camp bunks, RVs, guest beds, and daycare facilities.
Quick Reference for Cot Size Fitted Sheets:
- Standard dimensions: 30" x 75" (most common)
- Alternative size: 33" x 75" (jersey knit variant)
- Pocket depth: 7.5 inches (standard)
- Common uses: Camp cots, RV bunks, guest beds, daycare cots
- Materials: Cotton, poly-cotton blend, jersey knit, bamboo
- Price range: $14.99 - $19.95
As one product expert noted: "We know kids have a tough time making their beds, that's why we're here to help—our bunk sheets stay tucked in place." This perfectly captures why the right fitted sheet matters so much.
The fit is everything. Too loose and the sheet slips off during sleep. Too tight and you'll struggle to get it on the mattress. Unlike standard twin sheets that measure 39" x 75", cot sheets are specifically made for narrower mattresses that don't fit conventional bedding sizes.
Whether you're outfitting camp bunks, RV beds, or guest accommodations, the right cot size fitted sheet makes all the difference in comfort and ease of maintenance. These specialty sheets resist wrinkling, stay securely in place, and withstand frequent washing - essential features for high-use environments.
We're American Mortuary Coolers, and through years of working with funeral homes and understanding their specific bedding needs, we've gained extensive experience with cot size fitted sheet requirements and quality standards. This expertise extends to helping facilities choose the right bedding solutions for their unique space and operational demands.
What Is a Cot Size Fitted Sheet?
Think of a cot size fitted sheet as the little brother of regular bedding. It's specifically made for those narrow mattresses that leave you scratching your head in the bedding aisle because nothing seems to fit quite right.
The magic number here is 30" x 75" - that's your standard cot size fitted sheet dimension. Compare that to a regular twin sheet at 39" x 75", and you'll see why using the wrong size turns bedmaking into a wrestling match. That 9-inch difference might not sound like much, but it's the difference between sheets that stay put and sheets that pop off every night.
You'll find these narrow mattresses everywhere once you start looking. Camp bunk beds use them because they maximize sleeping space in cabins. RV manufacturers love them because every inch counts when you're designing a home on wheels. Guest daybeds often use this size, along with daycare cots where little ones take their afternoon naps.
Here's where it gets a bit confusing - some brands call these "narrow twin" sheets instead of cot size. Don't worry, they're talking about the same thing. It's like how some people say "soda" and others say "pop" - different words, same product.
| Sheet Type | Width | Length | Where You'll See Them |
|---|---|---|---|
| Cot Size | 30" | 75" | Camp bunks, RV beds, guest cots |
| Crib Size | 28" | 52" | Baby cribs, toddler beds |
| Twin Size | 39" | 75" | Regular single beds, most bunk beds |
The difference between cot and crib sheets is pretty straightforward too. Crib sheets are much shorter at 52 inches because babies don't need the full 75-inch length. Cot sheets are made for older kids and adults who need that extra length but not the full width of a twin bed.
Boat bunks are another common spot for cot-sized mattresses. Space is precious on the water, so marine manufacturers often go with these narrower beds. Same story with institutional settings like hostels or dormitories where they're trying to fit more sleeping spaces into limited square footage.

Standard Dimensions & Variations
Most cot size fitted sheets stick to that 30" x 75" measurement, but there are a few variations worth knowing about. The standard pocket depth is 7.5 inches, which works perfectly for most foam and spring mattresses you'll find on cots and narrow bunks.
Some jersey knit versions come in 33" x 75" to accommodate slightly wider narrow twin mattresses. These stretchy fabrics can handle a bit more give and take, making them forgiving if your measurements are close but not exact.
For ultra-compact camping setups, you might run into 25" x 75" sheets for those really narrow camping cots. And if you're dealing with toddler daycare equipment, some of those little naptime cots use 23" x 40" sheets - basically a shortened version of the standard size.
The pocket depth can vary too. While 7.5 inches is standard, some manufacturers offer deeper pockets up to 15 inches for thicker mattresses or if you've added a mattress topper. This extra depth ensures the sheet stays put even on bulkier sleeping surfaces.
Here's a pro tip from our years in the business: always measure before you buy. We've seen too many people guess at sizes and end up frustrated. The mattress itself might be labeled as 54" x 30" x 7.5" (that's length x width x height), but remember - the sheet size follows width x length, so you're looking for that 30" x 75" fitted sheet.
Materials, Design & Fit Guidelines
When you're shopping for a cot size fitted sheet, the material you choose can make or break your sleeping experience. Let's walk through what actually works in real-world situations.
Poly-cotton blends are the clear winner for most applications. The typical 80% cotton, 20% polyester mix with a 200 thread count offers the sweet spot between comfort and durability. These sheets hold up beautifully to frequent washing - essential when you're dealing with camp bunks or RV beds that see constant use.
Pure cotton feels wonderful against the skin and breathes well on hot summer nights. However, it wrinkles easily and tends to shrink if you're not careful with washing temperatures. Organic cotton takes this a step further, eliminating chemical treatments that might irritate sensitive skin - perfect for daycare settings.
Jersey knit cotton deserves special mention because it's naturally stretchy. This makes it ideal for those slightly wider 33" x 75" mattresses, and it feels cozy like your favorite t-shirt. Bamboo fabric is gaining popularity for its natural hypoallergenic properties and excellent breathability, though it typically costs more.
The 7.5-inch pocket depth is standard for most cot mattresses, but some manufacturers offer deeper pockets up to 15 inches for thicker mattresses or those with foam toppers. Getting this measurement right is crucial - too shallow and the sheet pops off, too deep and you'll have excess fabric bunching up.
Color selection has come a long way from basic white. Most quality brands now offer 15 or more colors, from practical navy and gray to cheerful patterns for children's spaces. Solid colors tend to hide stains better and match any decor.
Proper fit isn't just about comfort - it's about safety. This is especially important in childcare settings where loose bedding can pose risks. A snugly fitted sheet eliminates excess fabric while providing a smooth, secure sleeping surface.
To get the perfect fit, measure your mattress length, width, and height before ordering. Add 4-6 inches to the height measurement to ensure proper tuck-under. The sheet dimensions should match or slightly exceed your mattress size for optimal performance.
Elastic corners are what make fitted sheets superior to flat sheets for narrow mattresses. They grip the mattress securely and maintain their hold even with active sleepers.
Benefits of a Cot Size Fitted Sheet Versus Flat Sheet
Here's why a cot size fitted sheet beats a flat sheet every time for narrow mattresses.
The corners stay put. Those elastic corners grip your mattress like they mean business. No more waking up to find half your sheet on the floor - especially important when you're dealing with restless kids at summer camp.
Bed-making becomes simple. As one manufacturer puts it perfectly: "We know kids have a tough time making their beds, that's why we're here to help - our bunk sheets stay tucked in place." No hospital corners, no complex tucking, just stretch and go.
Everything stays smooth. A properly fitted sheet maintains its position throughout the night, creating a consistently comfortable sleeping surface. This is particularly valuable in RV bunks where space is tight and every bit of comfort matters.
Wrinkles become a non-issue. The snug fit prevents fabric from bunching and moving around, which naturally reduces wrinkles. Your bed looks neat longer, and you spend less time with the iron.
Better sleep quality naturally follows. When your sheet isn't sliding around or bunching up, you sleep more soundly. That's crucial whether you're camping, traveling, or hosting overnight guests.

Buying, Care & Versatile Uses
Shopping for a cot size fitted sheet can feel like hunting for a needle in a haystack. These specialty sheets aren't sitting on every store shelf, but once you know where to look, you'll find plenty of great options.
Amazon and Walmart lead the pack for selection and convenience. Amazon offers the widest variety with customer reviews to guide your decision, while Walmart provides budget-friendly options with the bonus of store pickup. If you're looking for something unique or want to save a few dollars, eBay has both new and gently used sheets in hard-to-find sizes.
For hands-on shopping, camping supply stores like REI understand the rugged demands of camp life. RV dealerships often stock bedding accessories, and they truly get the space constraints you're dealing with. Local bedding shops might need to special order, but they'll work with you to find exactly what you need.
Price-wise, expect to spend $14.99 to $19.95 per sheet. The Gilbins brand stands out with an impressive 4.9 out of 5 star rating from 29 reviews, known for their ultra-soft cotton that customers rave about. Whether you choose cotton, poly-cotton blend, or bamboo fabric affects the price, along with thread count and special features like deep pockets.
Caring for your sheets properly makes all the difference in how long they last. Machine wash in warm water (not hot—trust us on this one to avoid shrinkage). Skip the bleach and use mild detergent instead. Always wash new sheets before that first use.
When drying, stick to low heat and remove them promptly to prevent wrinkles. Air drying extends fabric life even more, though we know that's not always practical. Over-drying damages the elastic, which defeats the whole purpose of a fitted sheet that stays put.
Here's something that might surprise you: cot size fitted sheets work brilliantly beyond traditional cots. They're perfect for folding mattresses in guest rooms, sleeper chairs that convert for overnight visitors, and thick camping pads. Boat owners love them for marine bunks, and they even work well on foam pads used for meditation or exercise.
The compact 30" x 75" size makes these sheets incredibly versatile for anyone dealing with space constraints or non-standard sleeping arrangements.

Where to Buy the Best Cot Size Fitted Sheet
Finding the perfect cot size fitted sheet comes down to knowing your priorities and shopping in the right places.
Online marketplaces win for convenience and selection. You can read customer reviews, compare prices easily, and often find bulk purchasing options if you're outfitting a camp or facility. The return policies tend to be generous too, which matters when you're buying something sight unseen.
Specialty retailers bring expertise to the table. They understand the unique challenges of narrow mattresses and can guide you toward materials that hold up to frequent washing. Many offer custom sizing if you have an unusual mattress dimension.
Local bedding outlets let you feel the fabric quality before buying. There's something to be said for supporting local businesses, and the personal service often leads to better recommendations. You'll walk out with your sheets the same day too.
RV supply shops deserve special mention. These folks live and breathe mobile living solutions. They stock products designed for the unique demands of life on the road and understand how every inch of space matters.
When evaluating quality, look for reinforced elastic corners that won't give out after a few washes. Pre-shrunk fabric saves you from unpleasant surprises, and colorfast dyes keep your sheets looking fresh longer. Machine washable is non-negotiable, and make sure the pocket depth matches your mattress thickness.
The Gilbins brand consistently earns top ratings for good reason. With 4.9 out of 5 stars across 29 reviews, customers praise both the softness and durability. For institutional purchases or anyone needing multiple sheets, their quality justifies the investment.
