Tried And Tested Ways To Always Pick The Right Pajama Size

Finding that just right pair of pajamas can make all the difference for a good night’s sleep. You know the feeling—you pick out the cutest set, only to discover they’re riding up or hanging off you.

 
 
 
 

Over the years, we’ve learned a few tricks that make finding the perfect pajama size less of a guessing game and more of a science (or close to it!). In this article, we share tried-and-true tips to help you nail the fit on your next set of cozy PJs.


No. 1

Start with Your Measurements (and Don’t Wing It)

It might feel a little extra, but knowing your measurements is key. Grab a soft measuring tape, and jot down your waist, hips, inseam, and chest. Once you have these numbers, you can compare them with each brand’s size chart—it’s like your own pajama compass!

This really helps, especially with pajama pants from materials like fleece. Have you ever made the mistake of going by “small” or “medium” before, only to end up with PJ pants that bunch around your knees or are just way too short? Measuring yourself first makes a world of difference.

Check the Brand’s Size Guide (Because Sizes Aren’t Universal)

Oh, the joy of sizing that’s all over the place. One brand’s medium could be another brand’s extra-large. Each brand has its own sizing quirks, so when in doubt, check the size guide on the product page.

Some brands even tell you if their items run small, large, or true to size, which can save you from those pesky returns. A little time spent here saves a lot of time in the long run (and some disappointment, too).

No. 3

Look for Stretchy or Adjustable Waistbands

We’re a fan of pajamas that adapt to different body types, not the other way around. Pajama bottoms with stretchy waistbands or drawstrings are lifesavers. They’re forgiving and give you the flexibility to adjust them just right.

This especially matters with flannel pajamas, which are great for winter but not if they’re too snug. An adjustable waistband is the difference between feeling cozy and feeling like you’re wearing a straitjacket.

Think About Your Preferred Fit (Loose? Fitted? Both?)

We all have different preferences when it comes to how snug or loose our pajamas feel. If you love a looser fit, especially for pajama sets, size up if you want that roominess.

But if you like a closer fit, stay true to size—especially in fabrics like cotton or jersey, which have a bit of give but still feel structured. Choosing your size based on fit preference adds an extra layer of comfort.

No. 5

Consider the Fabric and Its Stretch (or Lack Thereof)

Fabric matters! Stretchy ones like jersey or modal are great choices because they’re forgiving if you’re between sizes. Non-stretchy fabrics like flannel or silk? Be a bit more careful there, as they don’t give you much wiggle room.

For flannel, make sure it’s not too tight—it should fit well without feeling stiff. Nothing worse than feeling like you’re wearing cardboard when all you want is something soft and cozy.

No. 6

Check Customer Reviews for Real-World Sizing Tips

Let’s be real—customer reviews are golden. People are honest, and if there’s anything wrong with the sizing, someone will mention it! Look for reviews from people with similar measurements to you, which can be a huge help. Reviews can save you more time than you can count, especially when buying online.

No. 7

Know the Return Policy Before You Buy

Even with all the prep work, sometimes pajamas just don’t fit as expected. So always check the return policy, especially if you’re buying online.

Free returns make life so much easier, and knowing I can exchange if needed gives you the confidence to order multiple sizes if you’re unsure. A good return policy means you can test the fit at home without any stress.

No. 8

Make Sure to Get the Right Length (Especially for Colder Months)

For those of us with cold feet (literally), making sure your pajama pants reach your ankles can be crucial. Flannel pants in particular should cover you up nicely for that extra warmth.

If you’re on the taller or shorter side, look for brands that offer tall or petite options. There’s nothing cozier than PJs that fit just right in length.

No. 9

Consider Sizing Up for Winter Pajamas

When it comes to winter pajamas, we suggest sizing up. A looser fit lets you throw on a layer or two if needed, like a thermal top. Plus, pajamas that are too tight in cold weather feel a bit restricting, and they don’t trap heat as well. So when it’s flannel season, give yourself a bit of extra room.

No. 10

Follow Wash Instructions to Avoid Shrinking

You’ve found the perfect pajamas, and then they shrink after the first wash—ouch. A quick tip is to always check the wash instructions and try cold water and air drying, especially with cotton or flannel. If your pajamas survive that first wash without shrinking, they’re usually good to go!

Takeaways

Choosing the right pajama size can significantly enhance your comfort and sleep quality. To ensure the perfect fit, consider the fabric's elasticity; softer materials like cotton or modal provide more room for movement. Always check the sizing chart provided by the brand, as sizes can vary between manufacturers.

Additionally, take your body shape into account and explore styles like relaxed fits or adjustable waistbands for added flexibility. Lastly, don’t hesitate to read customer reviews for insights on true sizing and fit experiences.

Following these simple yet effective tips will enable you to confidently select pajamas that fit well. This choice will ensure you enjoy the comfort and support necessary for a truly restful and rejuvenating night's sleep.
