Many parents wonder if a standard kids sleeping bag will actually fit their taller child, especially one approaching 5’7″. Finding the right bag is crucial for a good night’s sleep on a camping trip, and a bag that is too short or too narrow can ruin the whole experience.
Most kids’ bags are designed for children up to about 4’6″ or 5’0″, leaving a 5’7″ kid cramped in length and often squeezed in width. The real challenge isn’t just height, but the shoulder and hip room needed for a growing teenager who might be as wide as a small adult.
The Tall Kid Sleeping Bag Fix
If your child is over 4 feet tall, standard kids’ sleeping bags often feel too short and tight. They kick off the cover or feel cramped all night. The 74-inch length of this bag gives them room to stretch out comfortably.

Why Sleeping Bag Size Matters More Than You Think
I remember the first time I took my oldest son camping when he was around 5’5″. He crawled into his old kids’ sleeping bag and his feet were pressed right against the bottom seam.
By morning, he was miserable. He told me his shoulders felt squeezed and his legs were cramped all night. That one bad night almost ruined our whole trip.
The Emotional Cost of a Cramped Bag
In my experience, a sleeping bag that is too small does more than just cause physical discomfort. It creates frustration and tears that can make a child hate camping.
My son spent the next morning grumpy and tired instead of excited for our hike. He even asked if we could just go home early.
That moment taught me that a sleeping bag is not just gear. It is the difference between a child who sleeps well and one who is miserable.
Money Wasted on the Wrong Product
I have seen so many parents buy a standard kids’ bag for a taller child because it was cheaper. Then they end up buying a second bag a year later when the child outgrows it.
That is money down the drain. In my experience, it is smarter to buy a bag that fits now and allows a little room to grow.
Here are the real costs of getting it wrong:
- A bad night of sleep means a cranky child the next day
- You waste money on a bag your child will outgrow in months
- The child may refuse to go camping again because it was uncomfortable
How to Know If a Kids Bag Will Actually Fit Your Tall Child
Honestly, the best way to avoid the cramped sleeping bag nightmare is to measure your child before you buy anything. Have them lie flat on the floor and mark where the top of their head and bottom of their feet land.
Then add at least six inches for comfort. A bag that ends exactly at their toes will leave them cold and uncomfortable all night.
Look at the Shoulder Room, Not Just the Length
In my experience, taller kids are often wider in the shoulders and hips too. A kids’ bag that is long enough might still be too narrow for them to move.
My son is built like a string bean, but his shoulders still pressed against the sides of his old bag. He told me he felt like a sardine in a can.
Check the Temperature Rating Too
A bag that is too tight does not trap heat well. If the bag is snug against your child’s body, the insulation gets compressed and loses its warmth.
This means a bag rated for 40 degrees might feel much colder for a cramped sleeper. I learned this the hard way when my son woke up shivering despite a supposedly warm bag.
You do not want to spend money on a bag that leaves your child cold and miserable. What finally worked for us was finding a bag designed with extra room for growing kids, and honestly, this is what I grabbed for my own son and it solved every problem we had.

What I Look for When Buying a Sleeping Bag for a Taller Kid
After that miserable camping trip, I changed how I shop for sleeping bags entirely. I now ignore the cute patterns and focus on three things that actually matter for a comfortable night.
Check the Actual Length, Not the Age Label
I never trust a bag that says “ages 8-12” because kids come in wildly different sizes. My son was 13 and taller than some adults I know.
Instead, I look at the exact length in inches printed on the product page. If it does not list a length, I move on to another option.
Look for a Wider Cut in the Shoulders
A bag shaped like a straight tube will squeeze a taller child who has broader shoulders. I look for bags that mention a “contoured” or “generous” cut in the description.
This small detail made a huge difference for my son. He could finally roll over without fighting the fabric.
Make Sure the Zipper Goes All the Way Down
Full-length zippers let your child stick their feet out if they get too hot. This is a lifesaver for kids who sleep warm or toss and turn.
I once bought a bag with a half zipper and my son complained all night. Now I check for a zipper that goes past the knee at minimum.
Consider a Bag That Can Zip to Another
Some kids’ bags can be zipped together with a second bag to create more space. This is perfect for a growing child who might need extra width.
My friend uses this trick for her tall daughter and says it works like a charm. It gives the child room to spread out without buying an adult bag.
The Mistake I See People Make With Sleeping Bags for Tall Kids
I wish someone had told me this earlier: do not assume a bag labeled “junior” or “youth” will fit a 5’7″ child just because it sounds big. Most of these bags are still designed for kids under 5 feet tall.
I see parents grab a youth bag thinking it is the grown-up version of a toddler bag. In reality, it is often only a few inches longer and just as narrow.
Why Buying a Kids Bag for a Taller Kid Backfires
The biggest mistake is thinking a bag can stretch or that your child will not notice the tight fit. Kids notice everything, especially when they cannot move their legs.
My neighbor bought a youth bag for her 5’6″ daughter and the girl refused to use it after one night. She said it felt like sleeping in a sock.
What You Should Do Instead
Measure your child’s height and add at least eight inches for comfort. Then measure their shoulder width across the back.
Compare those numbers to the bag’s actual dimensions, not the age range on the tag. If the bag is not at least six inches longer and two inches wider than your child, keep looking.
You do not want to waste another night worrying if your child is comfortable. If you are tired of guessing and just want something that fits right now, this is the one I finally bought for my son and it solved our problem completely.

The One Trick That Saved Our Camping Trips
Here is the thing I figured out after wasting money on two wrong bags: a kids’ sleeping bag does not have to be the final answer. You can actually use a bag designed for smaller adults and it will fit your 5’7″ child perfectly.
I started looking at “junior” or “compact” adult bags instead of children’s bags. These are often shorter than a full adult bag but much wider than a kids’ bag.
Why This Works So Well
The shoulder and hip room in a compact adult bag is a major improvement for taller kids. My son went from feeling squeezed to having enough space to sleep on his side.
He could even pull his knees up without hitting the bottom of the bag. That one change made him actually look forward to camping again.
How to Find the Right One
Look for bags that say “junior” or “short” in the adult section. These are usually around 66 to 72 inches long, which is perfect for a kid up to 5’7″.
Check the packed size too. A compact adult bag often packs down smaller than a bulky kids’ bag, which makes it easier to carry on a hike.
The best part is that these bags cost about the same as a high-end kids’ bag. You get more room and better quality for the same price.
My Top Picks for a Sleeping Bag That Fits Taller Kids
After all that trial and error, I have landed on two sleeping bags that I actually trust for my own kids. These are the ones I recommend to friends who ask what to buy.
Coleman Autumn Glen Lightweight Sleeping Bag with No-Snag — Roomy Enough for Growing Kids
The Coleman Autumn Glen is the bag I grab when I want something simple and reliable. It has a generous 75-inch length that gives a 5’7″ kid plenty of room to stretch out without their feet hitting the bottom.
I love the no-snag zipper because my son used to get stuck zipping his old bag alone. The only trade-off is that it is a bit bulky to carry, but for car camping it is perfect.
- Ideal for camping in temperatures as low as 50°F
- May ship in packaging that reveals what's inside
Flantree Sleeping Bags for Adults Kids Camping Hiking Warm — The Best Fit for Narrow Shoulders
The Flantree bag is what I bought after my son complained about feeling squeezed in his old bag. It is designed with a wider cut that gives taller kids room to move their arms and legs freely.
I appreciate that it packs down small enough for a backpacking trip, which the Coleman cannot do. The only downside is the zipper can stick if you rush it, but my son learned to go slow and it works fine.

Conclusion
The biggest lesson I learned is that a kids’ sleeping bag is rarely wide or long enough for a child up to 5’7″, so always measure your child and check the bag’s actual dimensions before you buy.
Grab a tape measure and check your child’s height and shoulder width right now — it takes two minutes and could save you from a miserable camping trip and wasted money.
Frequently Asked Questions about Is a Kids Sleeping Bag Wide Enough for Taller Kids up to 5’7?
What size sleeping bag does a 5’7″ child need?
Your child needs a bag that is at least 72 inches long, which gives them about five inches of extra room beyond their height. Most standard kids’ bags are only 60 to 66 inches long.
I recommend measuring your child lying flat and adding six to eight inches for comfort. A bag that is too short will leave their feet pressed against the cold fabric all night.
Can a 5’7″ kid use an adult sleeping bag instead?
Yes, an adult bag is often a better choice for a taller child because it gives them more length and shoulder room. Look for a compact or junior adult bag if a full-size one feels too long.
In my experience, a compact adult bag fits a 5’7″ child perfectly without being overly bulky. My son uses one and he loves having room to move his legs.
What is the best sleeping bag for a tall kid who sleeps on their side?
Side sleepers need extra width in the hips and shoulders so they can curl up without feeling trapped. A bag that is too narrow will force them to sleep flat on their back.
I found that bags with a wider cut or contoured shape work best for side sleepers. The one I bought for my restless sleeper gave him enough room to roll over and finally get comfortable.

Will a kids’ sleeping bag labeled “junior” fit a 5’7″ teenager?
Not usually, because most junior bags are still designed for kids under 5 feet tall. The label can be misleading, so always check the exact length and width measurements.
I made this mistake once and my son barely fit inside the bag. Now I ignore the age labels and only look at the actual dimensions listed on the product page.
How do I know if a sleeping bag is wide enough for my child?
Measure your child’s shoulder width across the back while they are standing up straight. Then add at least two inches to that number to find a comfortable bag width.
If the bag’s width is not listed, look for customer photos or reviews that mention the shoulder room. I always check reviews from parents of tall kids before I buy.
Which sleeping bag for a tall kid will not let me down on a cold night?
You need a bag that is both long enough and well-insulated so your child stays warm even if they move around. A tight bag compresses the insulation and makes it less effective.
I have tested several options and the one that never let us down is roomy and warm. What finally worked for my family kept my son comfortable even when temperatures dropped below freezing.
