Ever tried to squeeze a growing kid into last year’s sleeping bag? Not fun. Whether you’re prepping for a family camping trip, a sleepover, or just want your child cozy at home, picking the right childrens sleeping bags size is the secret to sweet dreams-and zero midnight wake-ups. Let’s break down everything you need to know, from snuggly infant sleeping bags to roomy sleeping bags for teens. Ready to find the perfect fit? Let’s dive in!
Why Size Matters for Kids Sleeping Bags
Choosing the right size isn’t just about comfort-it’s about safety and warmth. A bag that’s too big lets cold air sneak in, while one that’s too small? Cue the tossing, turning, and grumpy mornings. The best kids sleeping bag hugs your child just right, giving them room to wiggle without losing heat.
Quick Tips:
- Measure your child’s height from head to heel.
- Add about 10–15 cm (4–6 inches) for wiggle room.
- Never size up “just in case”-a snug fit is safer for little ones.
Kids Sleeping Bag Size Chart by Age & Height
Here’s a handy guide to help you match your child’s age and height to the right sleeping bag size. Remember, kids come in all shapes and sizes, so always check the product’s specific measurements before you buy.
| Age Group | Child Height (cm/in) | Sleeping Bag Length (cm/in) | Typical Size Name | Notes |
| Infant (0–6 mo) | up to 68 cm / 27″ | 68–70 cm / 27–28″ | Infant / Baby | Snug neck & armholes, legs can move |
| 6–12 months | 68–80 cm / 27–31″ | 70–86 cm / 27–34″ | Baby | Choose by height, not age |
| Toddler (1–3 yrs) | 80–98 cm / 31–39″ | 86–104 cm / 34–41″ | Toddler | Room for legs, not too loose |
| Preschool (3–5) | 98–116 cm / 39–46″ | 104–116 cm / 41–46″ | Child / Preschool | Look for “child size sleeping bag” |
| Youth (6–12) | 116–152 cm / 46–60″ | 126–152 cm / 50–60″ | Youth / Junior | “Youth sleeping bag” fits best |
| Teen (13+) | 152–168 cm / 60–66″ | 152–168 cm / 60–66″ | Teen / XL Youth | “Sleeping bags for teens” or adult short |
Pro tip: If your child is between sizes, always go for the smaller one for safety, especially with infants and toddlers.
Infant Sleeping Bag Camping: Safe & Snug from Day One
For the tiniest campers, safety is everything. Infant sleeping bag camping options are designed to keep babies warm without any loose blankets. Look for:
- Snug fit at the neck and armholes
- Enough space for legs to move freely
- No extra fabric that could ride up
Popular sizes:
- 0–6 months: up to 68 cm (27″)
- 6–12 months: up to 80 cm (31″)
Best for: Home naps, stroller walks, and chilly nights at the campsite. Always check for a safe TOG rating for the season, and never use a padded sleeping bag in a car seat.
Toddler Sleeping Bag: Room to Grow, Not to Lose Heat
Toddlers are all about movement-even in their sleep! The best toddler sleeping bag gives them space to kick but stays fitted at the top. Look for:
- Lengths around 86–104 cm (34–41″)
- Soft, breathable materials
- Easy zippers or snaps for quick changes
Some brands even offer sleeping bags that “grow” with your toddler, saving you money (and sanity) as they sprout up overnight.
Youth Sleeping Bag: For Big Kids & Preteens
Once your child hits grade school, it’s time to upgrade to a youth sleeping bag. These typically fit kids from about 116 cm (46″) up to 152 cm (60″) tall. Features to look for:
- Adjustable length (like the REI Kindercone or Big Agnes Duster 15) so the bag “shrinks” for smaller kids and expands as they grow
- Durable, washable fabrics for campouts and sleepovers
- Fun prints or colors to make bedtime exciting
Check latest price on Amazon for the most popular youth sleeping bags-many offer adjustable sizing and extra comfort features.
Sleeping Bags for Teens: When They’re Almost Grown
Teens need more space, but they’re not always ready for a full adult bag. Sleeping bags for teens bridge that gap, fitting heights up to 168 cm (66″) and offering a bit more shoulder room[6]. Look for:
- Longer lengths (152–168 cm / 60–66″)
- Lightweight options for backpacking or travel
- Temperature ratings that match their adventure plans
See full specs on Amazon for top-rated teen sleeping bags, including models with adjustable hoods and extra insulation for cold nights.
How to Measure for the Perfect Fit
It’s easier than you think! Here’s how to size up your child for a sleeping bag:
- Have your child stand straight (or lay down for babies).
- Measure from the top of their head to their heels.
- Subtract their head length, then add 10–15 cm (4–6″) for wiggle room.
- Match this number to the sleeping bag’s length.
Example: If your child is 90 cm tall and their head is 20 cm, the ideal bag length is 90 – 20 + 10 = 80 cm.
What Else Matters? Key Features to Look For
Not all childrens sleeping bags are created equal. Beyond size, consider:
- Temperature rating: Make sure it matches your climate (summer vs. winter bags).
- Material: Cotton for breathability, synthetic for easy washing, down for warmth.
- Extras: Built-in pillow, fun prints, glow-in-the-dark zippers, or a matching carry bag.
- Safety: No loose cords or buttons, and a zipper guard to prevent pinched skin.

Quick FAQ: Kids Sleeping Bag Sizing
How do I know if a sleeping bag is too big?
If your child can slip their head inside the bag or the neckline is loose, it’s too big. Always go for a snug fit at the top with room to move legs.
Can my child use an adult sleeping bag?
Not recommended for younger kids-adult bags are usually too long and lose heat, making them less cozy and safe.
What about sleeping bags for sleepovers?
Look for lighter, machine-washable bags with fun designs. “Kids sleeping bag for sleepovers” is a great keyword to find options perfect for indoor use.
