Scroll through blanket-plush listings for more than a minute and you'll run into the same two numbers over and over: 100cm and 150cm. They show up in the title, in the size dropdown, sometimes in a size chart photo, but rarely with any real explanation of what they mean once the thing is actually unfolded on your couch or back seat. Here's what those numbers translate to in practice, and how to pick between them.

What "100cm" and "150cm" Actually Measure

On a plush-to-blanket hybrid, the size number refers to the blanket's width once it's unfolded, not the size of the plush shape it folds into. A 100cm blanket and a 150cm blanket both come folded into roughly the same huggable plush size on the shelf. The difference only shows up once you undo the closure and shake the fabric out flat.

Most of our two-size sets, like the PillowPuff Snuggle Critter set, run 100x170cm for the smaller option and 150x170cm for the larger one. The 170cm length stays constant between the two, so the size choice is really about width, not length.

Not every set in the line uses the same two numbers. Some, like our Reef Shark set, scale in three steps (60cm, 80cm, 100cm) instead of two, so it's worth checking the specific product's size chart rather than assuming every listing follows the 100/150 pattern.

100cm vs 150cm in Real-World Terms

• 100cm wide: comparable to a standard twin-size throw. Enough to fully cover one child on a couch, in a car seat, or under a reading lamp in bed, with a bit of overhang on either side.
• 150cm wide: closer to a small double-bed blanket. Wide enough for one adult to use fully stretched out, or for two smaller kids to share on a shared car seat or a movie-night couch spot.

Neither size is "wrong" for an adult, since even the 100cm version works fine as a lap blanket or a travel throw. The 150cm just removes the need to tuck your feet up to stay covered.

How to Pick Based on Who's Using It

• One young child, mainly for naps or car rides: 100cm is usually plenty and easier for small hands to fold back up on their own.
• Siblings sharing a back seat or a couch spot: either give each kid their own 100cm so nobody's tugging on someone else's blanket, or size up to 150cm if they're happy sharing one.
• An older kid, teen, or adult who wants to actually use it as a blanket: 150cm holds up better for regular use on a couch or bed.
• Mainly for display or as a smaller plush companion: the size difference matters less here since the blanket stays folded most of the time either way.

A Quick Way to Double-Check Before You Buy

If you're still unsure, measure the actual couch cushion, car seat, or bed the blanket will mostly live on and compare it to 100cm and 150cm in your head (roughly the width of a twin mattress versus a bit more than half a full-size mattress). It sounds basic, but it's the single fastest way to avoid ordering a blanket that's technically fine but noticeably smaller or bulkier than you pictured.

Our Blanket Buddies collection has both sizes across most of the plush styles we carry, so you can compare options side by side before deciding. If you're shopping for more than one size at once, our best-selling plushies collection is a good shortcut to the styles that tend to hold up best over repeated folding and unfolding.
