Most toddler beds use the same 52-by-28-inch mattress as a standard crib, but the frame and mattress still control the sheet size. These six cotton fitted sheets cover jersey and muslin choices, one- and two-sheet packs, and pockets from 5 to 9 inches.

Burt's Bees Baby Organic Cotton Sheet
Fabric
GOTS-certified organic cotton jersey
Size
52 x 28 inches
Pocket depth
5.5 inches
Elastic
360-degree
Pack
1 sheet
Burt's Bees Baby uses stretchy organic cotton jersey, a 5.5-inch pocket, and full-edge elastic. The selected floral print fits a crib-size toddler mattress and adds color without changing the basic fitted-sheet setup.
The moderate pocket works best on a mattress near that depth. One sheet is easy to try but leaves no clean backup after a nighttime accident.
Why It Works
- A defined 5.5-inch pocket makes sizing clear.
- Jersey stretch eases quick bedding changes.
What To Keep In Mind
- A single sheet needs a separate backup.
- Confirm the toddler mattress is crib size, not twin size.

KeaBabies Organic Cotton Crib Sheets
Fabric
Organic cotton jersey
Size
52 x 28 inches
Pocket depth
3–8 inches
Elastic
SnugFit band
Pack
2 sheets
KeaBabies offers the widest stated depth range, covering mattresses from 3 to 8 inches. The two organic cotton jersey sheets use a stretch knit and concealed elastic band for quick removal.
That broad range still needs a hands-on fit check. Make sure the elastic pulls every bit of spare fabric underneath a thin mattress.
Why It Works
- Two sheets support a practical laundry rotation.
- The stretch design accommodates several mattress depths.
What To Keep In Mind
- A broad fit claim does not guarantee every corner stays tight.
- Pattern selection may vary by listing option.

American Baby Company Cotton Sheets
Fabric
100% cotton jersey
Size
52 x 28 inches
Pocket depth
9 inches
Elastic
Full edge
Pack
2 sheets
This two-pack uses 100% cotton jersey with a deep 9-inch pocket. It is a practical match for a thicker crib-size toddler mattress and provides a second white sheet for immediate changes.
On a thinner mattress, the deep pocket may leave extra fabric. Test the fit after washing rather than folding excess material under the mattress.
Why It Works
- Two matching sheets simplify overnight changes.
- A 9-inch pocket covers a deeper toddler mattress.
What To Keep In Mind
- The pocket can be too deep for a low-profile mattress.
- White fabric shows stains quickly.

HonestBaby Organic Cotton Crib Sheet
Fabric
GOTS-certified organic cotton jersey
Size
52 x 28 inches
Elastic
All around
Pack
1 sheet
Care
Machine washable
HonestBaby pairs a GOTS-certified cotton jersey knit with extra-stretchy perimeter elastic. The Watercolor World print is made for both standard crib and crib-size toddler mattresses.
The listing offers singles and two-packs, so confirm the selected quantity. Pocket depth is not clearly stated in the retained details and should be checked before buying.
Why It Works
- Stretchy full-edge elastic supports fast changes.
- The print adds color without extra bedding layers.
What To Keep In Mind
- Confirm pocket depth and pack count.
- Certification does not prove mattress compatibility.

aden + anais Cotton Muslin Sheet
Fabric
100% cotton muslin
Size
52 x 28 inches
Pocket depth
8 inches
Pack
1 sheet
Care
Machine washable
aden + anais uses pre-washed cotton muslin with an open weave and an 8-inch pocket. The Country Floral print offers a different feel from jersey while fitting a deeper crib-size mattress.
Muslin feels lighter and more textured. Check that the tailored edge remains beneath every corner, especially on a mattress shallower than 8 inches.
Why It Works
- An 8-inch pocket suits deeper toddler mattresses.
- Pre-washed muslin provides a light woven alternative to jersey.
What To Keep In Mind
- The single sheet needs a backup.
- Deep pockets may be loose on thin mattresses.

Green Cotton Muslin Toddler Sheets
Fabric
100% cotton muslin
Size
52 x 28 inches
Pocket depth
5 inches
Pack
2 sheets
Care
Cold gentle wash
This two-pack has the shallowest muslin pocket at 5 inches. Looped elastic keeps the green sheets under a lower-profile crib-size toddler mattress, while cold gentle care helps protect their dimensions.
The shallower fit is the reason to choose this set over aden + anais. It will not correctly cover a mattress much deeper than 5 inches.
Why It Works
- The 5-inch pocket suits low-profile toddler mattresses.
- Two muslin sheets give you a ready backup.
What To Keep In Mind
- It will not fit a deep mattress correctly.
- Follow cold-water care and recheck after washing.
Confirm the Toddler Bed Size First
Many toddler frames reuse a crib mattress, but a twin bed does not. Check the frame manual and measure the mattress. The toddler sheet size guide and toddler sheets versus crib sheets comparison explain when the sizes overlap.
If you are still choosing the sleep surface, use the toddler mattress size guide before buying sheet sets. Do not rely on the word “toddler” alone.
Jersey Versus Muslin
Jersey is knitted for stretch and a smooth T-shirt feel. Muslin is woven with a more open texture. The toddler sheet materials guide helps compare fabric with care needs rather than marketing promises.
Whatever the fabric, keep the surface flat and the elastic under every corner. Wash as directed and replace sheets that tear, stretch out, or stop fitting. The crib sheet washing guide also applies to crib-size toddler sheets.
Plan for accidents
Two-sheet packs give you a basic rotation. If nighttime wetting is common, a compatible protector may also help; compare toddler mattress protectors without stacking thick pads for added softness.
For the wider bed transition, review when to switch from a crib to a toddler bed rather than changing the setup by age alone.
Frequently Asked Questions
Do crib sheets fit a toddler bed?
They often do when the toddler bed uses the same crib-size mattress. Confirm dimensions first.
Do toddler sheets fit a twin mattress?
No. A twin mattress is much larger than a crib-size toddler mattress.
Is jersey or muslin better?
Jersey stretches more, while muslin has a lighter woven texture. Correct fit matters more than weave.
What pocket depth should I choose?
Choose a pocket that covers the mattress side and keeps the elastic underneath without loose fabric.
How many toddler sheets do I need?
Two provide a basic rotation. Frequent accidents or limited laundry access may justify more.
Should I use sheet clips?
Do not use a loose sheet or add improvised clips inside the bed. Choose the correct fitted size.
