Longboard Wheel Size: What the Numbers Actually Mean for Your Ride
Longboard wheel size is measured in millimeters across the diameter. Most longboard wheels fall between 60mm and 75mm, and the right range for you depends on one thing: what surface you ride on most days. A bigger wheel rolls smoother over cracks. A smaller wheel accelerates faster from a stop. Neither is universally better — the right longboard wheel dimensions are the ones that match your route, not a spec sheet.
What longboard wheel size actually means
When a product listing says “70mm wheels,” that number is the diameter — the distance across the wheel from one edge to the other through the center. That single number tells you more about how the board will feel than almost any other spec on the page.
Here is the short version of what size of longboard wheels does to your ride:
- Bigger wheels (70–75mm) roll over cracks, pebbles, and rough pavement more easily. They maintain speed longer between pushes, which means less effort on commutes over a mile.
- Smaller wheels (60–65mm) accelerate from a stop faster and keep the board lower to the ground. They feel more responsive underfoot, but you will feel every texture change in the pavement.
- Mid-range wheels (65–70mm) split the difference — enough roll speed for campus commuting, enough nimbleness for navigating crowded paths.
This is not a “bigger is better” question. It is a “what surface do you ride” question. I had a buyer once who was set on a $200 board with 75mm wheels because a friend told him bigger was faster. His route was half a mile on smooth campus pavement. He did not need 75mm wheels — he needed something that could turn quickly between buildings. We ended up at a 68mm setup and he was happier with the feel than he would have been with the bigger wheels his friend recommended.
For a deeper breakdown of how diameter interacts with hardness, shape, and core placement, our full longboard wheels guide covers every variable in detail.
Longboard wheel size vs. your riding surface
Wheel diameter does not exist in isolation. The pavement under your wheels is what actually determines whether a given size feels right or feels wrong. Here is how to match longboard wheel dimensions to the ground you ride on:
| Surface type | Recommended size | What you will feel |
|---|---|---|
| Smooth bike paths, new asphalt | 65–70mm | Responsive turning, quick acceleration, you feel connected to the ground |
| Cracked sidewalks, older asphalt, brick | 70–75mm with 78A–82A durometer | Smoother roll, less vibration in your feet and legs, less fatigue over distance |
| Mixed campus routes (smooth paths + rough patches) | 70mm, soft durometer | Practical middle ground — handles both without compromising either |
| Smooth park paths, indoor concrete | 60–65mm | Quick, nimble, lower ride height, easy to push from a standstill |
The part most beginners miss: wheel softness matters as much as diameter for rough roads. A 70mm hard wheel (86A+) on cracked pavement will still feel harsh. A 70mm soft wheel (78A–80A) on the same surface will feel like a completely different board. We learned this the hard way through a buyer who left a detailed complaint about a board being “too rough” on city streets — the board was fine, but the wheels were 83A on a route full of hairline cracks. The fix was not a new board. It was softer wheels. That experience is why every product page on Groveride now includes surface-fit guidance.
Different board shapes also affect how wheels interact with the ground. If you are still deciding between board types, our guide to types of longboards explains how deck shape, truck mounting, and wheel clearance work together.
Common longboard wheel sizes and what they are for
Most riders do not need to memorize every millimeter option. The ranges below cover the vast majority of use cases. Start with your riding scenario, then find the matching size.
| Size range | Best for | Trade-off to know |
|---|---|---|
| 60–65mm | Cruiser skateboards, tight campus turns, short errands | Faster acceleration but you feel more road texture; lower top speed between pushes |
| 65–70mm | City commuting, campus riding, versatile all-around use | Good balance — not the fastest roll, not the most nimble turn, but solid at both |
| 70–75mm | Longer commutes, rougher pavement, beginners wanting a smooth first ride | Higher ride height means slightly more effort per push; may need riser pads on some setups |
| 75mm+ | Downhill, speed runs, riders who already know they want maximum roll | Overkill for commuting; requires clearance-compatible deck and trucks |
In our experience, most first-time buyers landing on a 38–42 inch complete longboard will have 68–72mm wheels out of the box. That range works well for campus and city routes in the one-to-three-mile zone, which is where most new riders actually spend their time. If that sounds like your situation, you probably do not need to change anything — just ride it for a few weeks and see how the surface feels.

Big longboard wheels: when they help and when they do not
There is a persistent idea in longboarding forums that bigger wheels are always an upgrade. Sometimes they are. Sometimes they create new problems you did not have before.
Here is what big longboard wheels actually do for you:
- They maintain roll speed longer. A larger circumference means fewer rotations per mile and less deceleration when you hit a crack or pebble. On rough surfaces, this is a meaningful comfort difference over any ride longer than ten minutes.
- They absorb more road texture. Combined with a soft durometer (78A–80A), bigger wheels reduce the vibration that travels up through the deck into your feet and legs.
Here is where they can work against you:
- They raise ride height. A taller wheel means your standing platform sits higher off the ground. That makes each push a little more effort and can make the board feel less stable for very new riders. Drop-through truck mounting offsets this by lowering the deck, which is one reason drop-through longboards pair naturally with 70–75mm wheels.
- Wheel bite risk increases. If the deck cutout or truck geometry does not provide enough clearance, a 75mm wheel can contact the underside of the deck during a sharp turn. Some boards need riser pads — small spacers between the truck and deck — to safely fit wheels above 72mm.
- Heavier and slower to start. Bigger wheels have more mass. From a dead stop, they take slightly more effort to get rolling. On a half-mile campus ride with frequent stops, this adds up.
For most beginner commuters on standard 38–42 inch boards, 70–72mm is the practical sweet spot. It is smooth enough for mixed pavement, fast enough for commutes up to two or three miles, and fits most board setups without clearance modifications. I had a buyer — Marcus — who started on a soft 70mm setup and within three months wanted something faster and more aggressive. His riding style changed; the board did not. If you already suspect you will want speed within six months, starting at 72–75mm saves you from an early wheel swap. But if you are genuinely unsure, 70mm is the safe, flexible starting point.

Wheel size is half the equation — durometer is the other half
Focusing only on diameter is the mistake I see most often. Wheel durometer — the hardness rating — works alongside size to determine how your board actually feels on pavement. A 70mm wheel at 80A (soft) and a 70mm wheel at 86A (firm) will ride like different wheels on the same road.
The short translation:
- Softer wheels (78A–82A) compress slightly under your weight and absorb vibration. They grip better on rough or dusty surfaces. For commuting on cracked sidewalks or older asphalt, this is usually the right starting point.
- Harder wheels (83A+) slide more predictably and roll faster on smooth, clean pavement. They transmit more road feel, which experienced riders sometimes prefer for control during slides or technical riding.
For a first board on mixed surfaces: prioritize soft durometer first, then choose diameter based on how rough your route is. This order matters because a soft 68mm wheel on bad pavement will feel better than a hard 75mm wheel on the same surface. The durometer does the comfort work; the diameter does the roll-speed work.
If you are upgrading wheels on an existing board, match the new diameter to your board’s clearance limits and match the durometer to your surface. Our wheel durometer and hardness guide walks through this step by step, including how to check clearance and what riser pads do.
Common questions, answered straight
What size wheels do longboards usually come with?
Most complete longboards ship with 68–72mm wheels, typically in the 78A–80A hardness range. This is a safe general-purpose size that handles campus commuting, city cruising, and casual weekend riding without modifications. If your route is mostly smooth pavement, you will not need to change anything for a while.
Are bigger longboard wheels always better?
No. Bigger wheels roll smoother on rough pavement and hold speed longer, but they also raise ride height (making pushing slightly more tiring) and can cause wheel bite on boards not designed for them. The right size depends on your surface, your deck shape, and how far you ride. For most commuters, 70–72mm covers the majority of needs.
Can I put bigger wheels on my longboard?
Usually yes, but you need to check clearance first. Wheels above 72mm may require riser pads between the truck and deck to prevent the wheel from contacting the underside during turns. Drop-through decks generally have more clearance for bigger wheels than top-mount decks. If you are unsure, measure the space between your wheel and the deck at full lean, or check the manufacturer’s maximum wheel recommendation.
Does wheel size affect speed?
Bigger wheels hold speed longer between pushes — they cover more ground per rotation and decelerate less on rough surfaces. Smaller wheels accelerate faster from a stop but lose speed more quickly. For commuting, maintaining roll speed over distance matters more than burst acceleration, which is why most commuter boards use 68–75mm wheels rather than 60mm options.
