Fingerboard Truck-to-Deck Width Compatibility Chart
The ideal fingerboard truck width matches your deck width as closely as possible: 29-30mm decks pair with 29mm trucks, 32mm decks with 32mm trucks, 33-34mm decks with 34mm trucks, and 36mm decks with 36mm trucks. Being off by 1-2mm in either direction is generally acceptable, but a bigger mismatch makes the setup feel unstable if the trucks are too narrow or sluggish if they are too wide. Use the chart below as the definitive quick reference when pairing new trucks to an existing deck, or a new deck to trucks you already own.
Why Width Matching Matters
Truck width and deck width work together to determine how balanced a setup feels. Trucks that are too narrow leave the deck without enough of a supporting base underneath, which makes the board feel tippy. Trucks that are too wide extend the wheelbase and turning radius beyond what the deck is shaped for, which slows down flips and reduces overall control.
Because deck and truck widths are not always manufactured to identical millimeter values, a small mismatch of 1-2mm is common and generally not worth worrying about. The chart below reflects the closest practical pairing for each common deck width.
How to Read the Chart
Find your deck width in the left column, then use the matched truck width in the middle column as your buying target for new trucks. If your deck falls between two listed widths, round to the nearest value rather than the farther one, since a small gap is far less noticeable than a large one.
The notes column calls out anything specific to that pairing, so you can see at a glance whether a given width is more forgiving or more sensitive to getting exactly right.
When It Is Okay to Deviate From the Chart
This chart reflects the standard, balanced pairing for each deck width, but deliberate deviation is a legitimate tuning choice once you know what you are chasing. Riders who want extra stability for park-style riding sometimes size trucks slightly wider than the deck on purpose, accepting slower flips in exchange for a more locked-in feel.
Riders chasing faster, more technical flip combos sometimes go slightly narrower instead, accepting a bit less stability for quicker rotation. Treat the chart as the default starting point, not a rule that overrides your own riding goals once you understand the tradeoffs.
Truck-to-Deck Width Compatibility Chart
| Deck Width | Ideal Truck Width | Notes |
|---|---|---|
| 29-30mm | 29mm | Keeps narrower decks proportionally stable; avoid sizing up here |
| 32mm | 32mm | The most common narrow-to-mid pairing for technical riders |
| 33-34mm | 34mm | Matches the most popular and widely available deck width |
| 36mm | 36mm | Wider trucks reinforce the stability wide decks are chosen for |
Frequently asked questions
What size trucks do I need for a 34mm fingerboard deck?+
34mm trucks are the ideal match for a 33-34mm deck, since 34mm is the most common and most widely stocked deck width.
What size trucks fit a 32mm fingerboard deck?+
32mm trucks are the ideal match for a 32mm deck. This is one of the most common width pairings for technical, flip-focused riding.
How far off can truck width be from deck width?+
A mismatch of 1-2mm in either direction is generally fine and often unavoidable. Bigger mismatches start to noticeably affect stability and flip speed.
What happens if I put 36mm trucks on a 32mm deck?+
The setup will feel sluggish and less controlled, since the wider trucks extend the turning radius and wheelbase well beyond what the narrower deck is shaped for.
Do all fingerboard decks list an exact width in millimeters?+
Most do, but manufacturing tolerances mean actual widths can vary slightly from the advertised number. Use the advertised width to find the closest chart match rather than expecting an exact millimeter match.
Is there one truck width that works for every deck?+
No. Truck width is deck-dependent by design; the whole point of matching width is to keep the setup's proportions balanced for the specific deck you are riding.
