The board size mainly depends on the kid’s height and weight. A slide change of height or weight can change the board’s size. So, you should buy a little bit longer board from the kid’s size.

So that they can learn with it while they grow up. Grom surfboards are generally 19-20″ wide. A Grom surfboard is generally small so the surfers can easily fit their arms around the board so the groms can reach their hand to the paddle. 

The length of the board depends on the surfer’s height. The surfer’s height will increase day by day. So, I advise you to choose a slightly longer board than the surfer’s size.

So they can learn to surf with it while growing up. If the kid is a pre-teen/ early teen then the length should be 0.6 meters longer than the kid’s size.

And if the kid is closing in on adulthood then it should be 0.3 meters longer. A slightly extra volume is always helpful for them to paddle past the impact zone and into the waves with comfort.

What Grooms Need in a Grom Surfboard

What Grooms Need

A Grom board should be short in length and around 20 inches wide. It should have a smaller body size so the surfers can easily balance it.


The grooms don’t know which shape is perfect for them. They just choose the design of the board and start practicing surfing with it. We adults must help them choose the right shape for them. 

Your grom won’t try to surf on massive waves before master surfing. They will just play on little waves unless they master surfing.

So it’s not necessary to choose the shape in the beginning. Just let them practice until they discover everything about surfing. But a tail shale board is perfect for kids to start with. 

Unless your kid is an expert surfer, you can skip the pintail and use a square tail, a squash tail. And for the expert surfers, you should choose a swallowtail.

There is no need for any overly forceful rocker in a grom surfboard. A standard single or double concave will be enough.

Fun Shapes and Longboards

A Grom board is generally made for kids. But it also has Fun shapes and longboards too. There are short grom boards everywhere in the market but there are plenty of longboards too.

The fun shapes and longboards help the groms to master surfing easily before shifting into a shortboard. A fun shape or longboard is specifically made to help your grom to learn the basics of surfing.

If the width is larger than the surfer’s arm’s reach then it would be difficult for a beginner to control the board. That’s why a fun shape or longboard is a better choice for starting.
