Buying your child’s first skateboard shouldn’t feel like guesswork. Parents come into the shop or call us most days asking the same thing: what size does my kid actually need? Age is a useful starting point, but it’s not the whole story. Height, confidence, and what your child wants to do on the board all matter too.
This guide walks through how we size skateboards for kids in the shop every day, so you can choose with confidence rather than picking the first board that looks fun on a website.
Two seven-year-olds can be very different sizes. One might be small for their age and still finding their balance, while another is tall, sporty, and ready for more board under their feet. Age gives you a rough starting point, but height is the better guide, and riding style matters once your child has a few sessions in.
At Skatewarehouse we work through it in this order: age first, then height, then how your child plans to ride (cruising around versus trying tricks), then deck width, and only then shoe size. Shoe size gets mentioned a lot online, but it’s the last thing to check, not the first. Any deck width is technically rideable with any shoe size — it’s comfort and control that really matter.
Here’s the logic we use day to day:
| Rider | Typical age / height | Best starting point | Why |
|---|---|---|---|
| Junior rider | Ages 3–10, usually under 5ft | Junior complete, around 29 inches long, 7.25–7.5 inches wide | Easier for smaller riders to carry, stand on, and turn |
| Transition-age rider | Roughly ages 10–13 | Full-size complete, usually 7.75–8.0 inches wide | Often too big for a junior board, but still growing into full-size |
| Teen beginner | Most teenagers and new full-size riders | 8.0 inch complete | The best neutral starting point |
| Adult beginner / taller child | Taller riders and older teens | 8.25 inch complete | More stability without feeling oversized |
This isn’t a strict rule — it’s a sensible starting point that we adjust based on height and confidence.
If your child is under 5ft tall, which usually covers ages 3 to 10, we’d normally start with a junior complete skateboard. Most junior boards are around 29 inches long and 7.25 to 7.5 inches wide. That smaller footprint makes it easier for a younger rider to push, turn, and feel in control.
At this age, kids are learning to stand comfortably, roll, and get a feel for the board. They’re not usually doing technical tricks yet, so there’s no need to jump straight to a full-size setup just because it looks more grown-up. A junior board that fits properly will help your child progress faster than a board that’s too big for them.
Our junior and mini youth complete skateboards are built properly, not toy-shop rubbish, and arrive ready to ride with grip tape already applied.
This is the tricky bit that a lot of sizing guides skip over. Somewhere between 10 and 13, most kids outgrow junior boards but still feel a bit small on a standard adult-width complete. If your child is on the smaller side for their age, a 7.75 inch complete is a good middle ground. It keeps the board lighter and easier to learn tricks on, while giving them the extra length a junior board doesn’t have.
If your child is already tall or broad for their age, it’s fine to skip straight to an 8.0 inch board. Height matters more than the number on their birth certificate here.
Our complete skateboards for beginners collection covers this in-between stage well, and our beginner skateboards for ages 10 and up collection is worth a browse too.
For most teenagers, we’d start with an 8.0 inch complete. It’s the best neutral middle ground — wide enough to feel stable, not so wide that it’s hard to flip or ollie. Once your teenager has ridden it for a while, they’ll know whether they want something narrower for street tricks or wider for skatepark stability.
Taller teens or those mainly interested in cruising rather than technical tricks can comfortably go up to 8.25 inches. Wider decks feel more stable underfoot, but they’re heavier and slightly harder to flip, so it’s a trade-off worth mentioning to your child rather than deciding for them.
A complete skateboard means deck, trucks, wheels, bearings, and grip tape all built and ready to go — no separate parts to buy, no assembly needed beyond maybe tightening the trucks to preference. That’s exactly why completes are the easiest way for a family to get started.
Most decks, including junior sizes, are built from North American maple wood — seven thin layers pressed together, which is what gives a proper skateboard its strength and snap. A properly built complete rolls better, turns more predictably, and lasts far longer than a boxed toy-shop board with a soft plastic deck and low-grade wheels. It won’t necessarily cost much more, but it will make learning noticeably easier, which matters far more in the first few months than it might seem.
A few things trip parents up more than anything else:
Once you know roughly where your child fits, here’s where to go next:
If you want the fuller picture on choosing a first board beyond sizing, our guide on buying your first skateboard, a beginner’s guide covers deck shape, trucks, and wheels in more depth. Our best skateboards for kids size guide is also useful if you want specific board recommendations to go with the sizing logic here.
Most 5 year olds are under 5ft tall, so a junior complete around 29 inches long and 7.25 inches wide is usually the best starting point. It’s easier to carry, stand on, and control than a full-size board.
It depends more on height than age at this point. If your 7 year old is still under 5ft, stick with a junior complete around 7.25–7.5 inches wide. Taller-than-average 7 year olds can sometimes move into a smaller full-size board, but junior is the safer starting point.
Yes, essentially. A junior complete has the same basic parts — deck, trucks, wheels, bearings, grip tape — just scaled down in length and width to suit a smaller rider. It’s not a toy version, it’s a proper skateboard built for a smaller frame.
At 10, most kids are in the transition zone. If they’re on the smaller side, a 7.75 inch complete works well. If they’re already tall or sturdy for their age, an 8.0 inch board is a good option. Riding style matters too — narrower for tricks, wider for stability.
Height matters more than weight for sizing. A taller or bigger-built child usually benefits from a slightly wider deck for better foot placement and stability, even if they’re on the younger side age-wise.
Size for now. A board that’s too big is harder to control and can slow down learning, or put your child off altogether. Kids progress quickly once they’re comfortable, so it’s easy to size up for their next board in a year or so.
