There's two ways to decide
1. Base it off your shoe size.
Here’s a list showing the ideal board sizes for each shoe size. Shoes sizes are in men’s US sizing and deck width measurements are in inches.
Size 2 to 5 – 7” up to 7.5” board
Size 6 to 9 – 7.5” up to 8.25” board
Size 9 and up – 8.25” board and wider
For the little ones who have a shoe size of 1 or smaller, we recommend a mini board. These are shorter than standard boards and are usually around 7” wide.
OR
2. Base it on the type of skateboarding you want to do.
Typically, more technical skaters who perform many flips, manuals and ledge tricks will skate boards between 7.75” and 8.25”. Skateboarders who prefer to skate big bowls, handrails and down big stairs will usually skate a board width of 8.25” or wider.
TIP
Thinner boards are great for beginners as they're easier to steer and handle. Wider boards are great for transportation as they provide a larger, more stable platform.
