Choosing the right bodyboard is the single most important decision you'll make to maximize your fun and progression in the water. A board that's too small will sink, making it difficult to paddle and catch waves. A board that's too big will be clumsy and hard to control. This calculator uses a proven formula based on your height, weight, and riding style to help you find the perfect size.
Calculate Your Ideal Bodyboard Size
Why the Right Bodyboard Size Matters
Bodyboard size directly impacts three key areas of performance: flotation, paddling, and control.
- Flotation (Buoyancy): The primary function of your board is to float you at the correct height in the water. Proper flotation keeps your upper body out of the water, reducing drag and allowing you to paddle faster. If your board is too small for your weight, you'll sink too low, making it feel like you're dragging an anchor.
- Paddling and Wave Catching: With the right amount of float, you can paddle efficiently and generate the speed needed to catch waves. A correctly sized board helps you get into waves earlier and with less effort.
- Control and Maneuverability: Once you're on a wave, you need to be able to control your board. A board that's too large will be difficult to turn and manage on the wave face. A board that's sized correctly will feel responsive and allow you to perform turns, spins, and other maneuvers with ease.
How to Manually Measure for a Bodyboard
If you're in a surf shop without this calculator, you can use a simple rule of thumb. Stand a board on its tail in front of you. The nose of the board should reach your belly button, or within an inch above or below it. This is the most widely accepted method for finding a baseline size.
Example Calculation
Let's see how the calculator works for a hypothetical rider:
- Height: 5'10" (70 inches)
- Weight: 170 lbs
- Riding Style: Intermediate (Prone)
The calculator first determines a base length from height (approx. 40.6″). It then applies a small adjustment for weight (in this case, 170 lbs is a baseline, so no adjustment). Finally, it considers the riding style (intermediate prone is also a baseline). The final recommended size is rounded to 40.5 inches, a perfect all-around size for this rider.
Frequently Asked Questions (FAQ)
What if I'm between two sizes?
If the calculator suggests a size like 41.5″ but you can only find 41″ and 42″ boards, consider your local waves. If you typically ride smaller, weaker waves, sizing up to the 42″ will give you extra float and help you catch them. If you ride powerful, steep waves, sizing down to the 41″ will offer more control.
Does the board's core material matter?
Yes, but it's a secondary factor to size. The main core types are Polypropylene (PP), which is lighter, stiffer, and best for warm water, and Polyethylene (PE), which is heavier, more flexible, and better for cold water. Your first priority should always be getting the right size.
What about board tail shapes?
The two main tail shapes are Crescent and Bat. The Crescent tail is the most common and versatile, offering good control for all skill levels. The Bat tail provides more lift to the back of the board, which can increase speed but may feel looser for beginners. For your first board, a crescent tail is a safe and effective choice.
