When people search for truck sizes skateboard advice, they usually want one simple answer: which truck width fits my deck? The short version is that your truck axle width should closely match your deck width, usually within a small margin, so the wheels sit near the edges of the board without sticking out far or tucking too far underneath. This guide explains the truck sizes skateboard sizing chart in full, how to measure both parts, and what to do when your setup falls between sizes, so you can choose with confidence instead of guessing at the shop counter.
Skateboard trucks are the metal T-shaped assemblies that connect your wheels to your deck. Each truck has an axle, which is the horizontal bar the wheels spin on, a hanger, which is the triangular body, a baseplate that bolts to the deck, and bushings that control how the truck turns. When skaters talk about truck size, they almost always mean axle width, measured from the outer edge of one axle nut area to the other, or sometimes the hanger width. Different brands measure and label their sizes differently, which is why a sizing chart matters more than a single number: the same nominal size can measure slightly differently across brands.
Getting the match right matters because trucks shape how your board feels. Trucks that are too narrow make the board feel twitchy and reduce stability, and they can make landing tricks feel cramped. Trucks that are too wide make the board feel sluggish to turn, add unnecessary weight, and leave axle ends exposed where they can catch on rails, ledges, and other obstacles. A close match keeps your wheels under the deck edges, preserves the turning response the deck was designed for, and helps your feet feel balanced over the board. That is why the truck sizes skateboard chart is the starting point for almost every setup question.
Truck Sizes Skateboard Chart: Deck Width to Truck Width
The standard rule is simple: match axle width to deck width as closely as possible. A deck measured at 8.0 inches wide pairs naturally with trucks whose axle measures around 8.0 inches. Most brands offer trucks in steps of roughly a quarter inch, so you can usually find a close match for any common deck size. The table below summarises the usual pairings used in skate shops and sizing guides.
| Deck width (inches) | Typical axle width (inches) | Common truck size labels |
|---|---|---|
| 7.5 | 7.5 to 7.75 | Small or low sizes, often labelled 129 or similar |
| 7.75 | 7.75 to 8.0 | Mid-small sizes, often labelled 139 or similar |
| 8.0 | 8.0 to 8.25 | Medium sizes, often labelled 149 or similar |
| 8.25 | 8.25 to 8.5 | Medium-large sizes, often labelled 159 or similar |
| 8.5 | 8.5 to 8.75 | Large sizes, often labelled 169 or similar |
| 8.75 to 9.0 | 8.75 to 9.0 | Wide sizes for cruisers and transition boards |
These labels vary by brand, and that variation is the biggest source of confusion in any truck sizes skateboard discussion. One brand may call an 8.0-inch axle a 149, while another uses a different numbering system entirely, and some brands list hanger width instead of axle width on the packaging. Before you buy, check the brand’s own size chart for the actual axle measurement in inches or millimetres, and compare that number to your deck width rather than trusting the label alone. A few minutes of checking can save you a return trip to the shop.
Truck Sizes Skateboard Measuring: Deck and Axle
Measuring your deck is straightforward. Lay the board flat and measure across the widest point, which is usually near the middle of the deck, from one edge straight across to the other. Most decks print their width on the top or bottom graphic, but if the print has worn off, a tape measure gives you the answer in seconds. Record the width to the nearest eighth of an inch, because that precision is enough to choose between neighbouring truck sizes.
Measuring trucks takes a little more care. If you already own trucks, measure the axle from the outside of one axle end to the outside of the other, not including the nuts, and note whether the brand quotes hanger width instead. If you are shopping online, use the product specification table rather than the product title, and look for the axle width figure specifically. When two sizes straddle your deck width, for example an 8.0-inch deck with truck options at 7.9 and 8.2 inches, either will usually work, and most skaters pick the closer match or the slightly wider option for a touch more stability.
Axle Width Versus Hanger Width
Axle width is the full span across the axle ends, while hanger width is the width of the triangular hanger body alone, which is narrower. Some brands headline the hanger width, which makes their trucks sound smaller than a rival’s axle measurement even when the finished setups are identical. Always compare like with like: axle to axle. If a listing only gives hanger width, look for the brand’s conversion chart or a specification sheet that lists both figures before deciding.
Truck Sizes Skateboard Choices Between Sizes
Between-size choices come up constantly, because decks come in quarter-inch steps and truck ranges do not always line up perfectly. As a general guide, staying within about a quarter inch of your deck width in either direction is safe for most street and park skating. Slightly narrower trucks will feel a little more responsive and lighter, which some technical skaters prefer, while slightly wider trucks will feel more planted and stable, which suits faster riding and transition skating. Neither choice is wrong; it is a matter of feel, and feel is personal.
What you should avoid is a large mismatch, such as pairing 7.5-inch trucks with a 9-inch cruiser deck, or wide transition trucks with a narrow street deck. Large mismatches change how the board turns, how it lands, and how the wheels contact the ground during grinds, and they can make a well-chosen deck feel like a different board entirely. If you are buying a complete setup, let the deck width lead the decision and choose trucks to match it, rather than picking trucks first and hoping the deck catches up.
Beginners sometimes ask whether they should size up as they grow or improve. The honest answer is that your deck width should drive the choice at every stage. Younger or smaller skaters usually ride narrower decks, and their trucks should match those decks, while taller skaters or those who prefer wider boards need wider trucks to match. Changing deck width without changing trucks is one of the most common setup mistakes, and it is easily fixed by checking the chart again whenever you switch decks.
Truck Sizes Skateboard Guide: Height, Bushings, and Wheels
Width is the headline number, but truck height also affects your setup. Low trucks sit closer to the deck and suit smaller wheels and technical street skating, while high trucks give more clearance for larger wheels and suit cruising and transition riding. Mid-height trucks split the difference and work well for all-round skating. Height does not change the width chart, but it does change wheel clearance, so if you ride larger wheels, make sure your truck height leaves enough room to avoid wheel bite, where the wheel contacts the deck during hard turns.
Bushings, the small urethane cushions inside the truck, control turning feel independently of width. Softer bushings turn more easily, harder bushings feel more stable, and most trucks ship with medium bushings that suit a wide range of riders. If your board feels too twitchy or too stiff after matching width correctly, bushings are usually the first thing to adjust, before you blame the size. Wheel size matters too: larger wheels roll faster and handle rough ground better, while smaller wheels accelerate quickly and suit technical tricks, but neither changes the width match between truck and deck.
When you are fitting new trucks, take time to set them up properly. Tighten the kingpin nut gradually until the trucks turn smoothly without wobbling, and check that both trucks feel even. Uneven tightness makes a board turn strangely no matter how well the widths match. After a few sessions, bushings break in and the feel settles, so give a new setup a fair trial before deciding the size was wrong.
Truck Sizes Skateboard Recap: Using the Chart Well
If you remember only one habit from this guide, make it this: whenever you change decks, run through the truck sizes skateboard chart again instead of assuming your old trucks still fit. The truck sizes skateboard chart is a quick check, not a chore, and it prevents the most common setup mistake in skating. A second useful habit is to write down your deck width and your axle width when you find a combination you love, because that record makes the next truck sizes skateboard purchase easy. Finally, remember that the truck sizes skateboard numbers describe width only: height, bushings, and wheels still shape feel, so judge a new setup over several sessions, not a single ride, before deciding whether the truck sizes skateboard match you chose was right.
Truck Sizes Skateboard FAQ
Should truck width exactly equal deck width?
As close as possible is ideal, and within about a quarter inch either way is fine for most skaters. Exact equality is not required, and small differences come down to personal feel.
Why do truck sizes differ between brands?
Brands use different numbering systems and sometimes quote hanger width instead of axle width. Always compare the actual axle measurement in inches or millimetres from the brand’s own chart.
Are wider trucks better for beginners?
Not automatically. Beginners benefit most from trucks matched to their deck width, because a matched setup feels balanced and predictable, which builds confidence faster than an oversized setup.
Do I need new trucks if I change deck width?
If the new deck is more than about a quarter inch different in width, new trucks matched to the new deck will keep the setup feeling right. For a full guide to getting any gear fitted well, see this fitting guide, and for a broader look at how to research gear choices, this comprehensive guide is a useful companion.
Conclusion
The truck sizes skateboard chart boils down to one rule: match axle width to deck width, check the brand’s real measurements rather than the label alone, and stay within about a quarter inch when you fall between sizes. Get that match right, and the rest of your setup, from bushings to wheels, can be tuned around a board that already feels balanced. Whether you are building your first complete or refining a setup you have ridden for years, the chart above is the fastest route to trucks that feel like they belong under your deck.
