Deck Widths Explained: How to Choose and Compare Fingerboard Sizes

Fingerboard deck width is measured in millimeters across the widest point of the board, typically at the center between the nose and tail kicks. Width is one of the primary specs listed by pro-tier brands and one of the most commonly missing specs in used marketplace listings. Knowing how width categories are described helps buyers search more accurately and ask sellers the right questions.^1, 2, 3

• 01Width is measured in millimeters (mm) at the widest point across the deck
• 02Width is distinct from length — most pro decks share similar length ranges, but width varies across brands and molds
• 03The same brand may offer multiple widths from the same shape/mold
• 04Width affects truck compatibility: truck axle width should generally match deck width

29mm is documented as an available width by brands including Berlinwood (via Blackriver Shop) and Teak Tuning, among others. Community discussions describe 29mm as associated with faster or lighter flip feel, though these descriptions reflect personal preference and are not universal. It is a narrower, earlier-era width that several brands still make in popsicle shape — named examples include Teak Tuning's 'The Classic' (29mm × 96mm), DK Fingerboards' 29mm popsicle blank, FlatFace's G15 in 29mm, and Boardkennel's 'Blind Popsickles'. On the used market it is generally less common than 32–34mm.^{3, 4, 5, 6, 7}

• 01Documented by Berlinwood (via Blackriver Shop), Teak Tuning, DK Fingerboards, and FlatFace
• 02Named 29mm molds include Teak Tuning 'The Classic' (29mm × 96mm), DK's 29mm popsicle blank, FlatFace G15 (29mm), and Boardkennel 'Blind Popsickles'
• 03Community-described as narrower feel with faster rotation — personal preference varies
• 04Generally less common in current used marketplace inventory than 32–34mm

32mm is described by multiple brands and community guides as a widely used starting point and a broadly available width category. Berlinwood, Teak Tuning, Blackriver trucks, and other sources document 32mm as a standard offering. Community discussions commonly describe 32mm as a natural fit for a range of finger placements, though this varies by individual.^{3, 1, 2, 8, 7}

• 01Documented by Berlinwood, Teak Tuning, DK Fingerboards, and Blackriver trucks
• 02Widely available in both new and used listings
• 03Compatible with 32mm trucks
• 04Popsicle shape is a common shape at this width — other shapes also exist

Several brands offer decks in a mid-size range around 33mm to 33.6mm, with the exact figure varying by brand: Berlinwood documents 33.3mm, FlatFace documents 33.6mm (its G16 shape, which it notes works with both 32mm and 34mm trucks), and Five Luck documents 33.3mm and 33.5mm, among likely others. Because the precise measurement differs between makers, buyers should confirm the exact number rather than assuming a deck labeled 'mid-size' or 'between 32 and 34' matches any specific brand's product.^{3, 6, 9, 1}

• 01Berlinwood documents 33.3mm; FlatFace documents 33.6mm (G16); Five Luck documents 33.3mm and 33.5mm
• 02Other brands offer similar mid-size widths — the exact figure (33.3 / 33.5 / 33.6mm) varies by maker
• 03FlatFace notes its 33.6mm G16 pairs with either 32mm or 34mm trucks
• 04May appear in listings as '33mm,' '33.3mm,' '33.6mm,' or informally as 'between 32 and 34'

34mm is documented by Blackriver trucks (as a compatible truck width), by Teak Tuning, and by multiple community guides as a currently common pro-setup width. Community discussions frequently describe 34mm as a broadly used width in current setups, though individual preferences vary. Teak Tuning's published width guide identifies 34mm alongside 32mm as one of the two most commonly referenced sizes.^{10, 1, 8, 2}

• 01Documented by Blackriver trucks (34mm listed as a truck width option)
• 02Documented by Teak Tuning as a current standard offering
• 03Widely referenced in community guides as a common current-era pro width
• 04Compatible with 34mm trucks

36mm is documented as a width option by Berlinwood (via Blackriver Shop) and Blackriver trucks, and some brands go wider still: Caramel documents named decks at 38mm (such as 'Gutter Frog' and 'Clown') and 40mm (such as 'Fear' and 'Godzilla'). Goo LTD also makes named molds in this wider territory — its 'Wide Life Crisis' mold is named for a wider profile, though Goo does not publish an exact width. Community references to 'wide setups' generally mean anything wider than 34mm, but the cutoff is not standardized, so the exact millimeter measurement matters more than the 'wide' label.^{3, 10, 11, 12, 1}

• 01Berlinwood documents 36mm as a distinct catalog width; Blackriver trucks lists 36mm as a truck width
• 02Caramel documents wider decks above 36mm — 38mm ('Gutter Frog', 'Clown') and 40mm ('Fear', 'Godzilla')
• 03Goo LTD makes named wider molds (e.g. 'Wide Life Crisis'), but its product pages do not publish an exact width — ask the seller to measure
• 04Above ~36mm, compatible trucks are harder to find — confirm a wide truck exists for the exact width before buying a deck

Deck shape (concave, nose and tail kick angle, wheelbase) is documented separately from width by most pro brands, but the two specs interact in how a setup feels. Concave refers to the curve across the width of the board — low concave has a flatter cross-section, high concave has a more pronounced curve. Wheelbase is the distance between mounting holes and affects stability. A deck at the same width can feel different depending on its concave and wheelbase, so buyers comparing listings by width alone may miss meaningful differences.^{3, 13, 14}

• 01Concave: low (flatter), medium, or high (more curved) — documented by Berlinwood and others
• 02Wheelbase: distance between mounting holes — longer wheelbase is generally described as more stable
• 03Kick angle: the steepness of the nose and tail — affects pop feel
• 04Shape (e.g., popsicle) describes the overall outline — popsicle is symmetrical nose and tail
• 05Two decks at the same width may have different concave, wheelbase, and kick, affecting feel

The generally recommended practice is to match truck axle width to deck width so that wheels sit close to the edge of the deck without overhanging significantly. Blackriver trucks are documented at widths of 29mm, 32mm, 34mm, and 36mm, which correspond to the deck widths they document for Berlinwood. When truck width does not match deck width, the axle extends past the deck edge or sits inset from it, which some riders prefer and others do not — personal preference applies here, but the mismatch should be disclosed in a listing.^{10, 3, 15}

• 01Standard guidance: match truck width to deck width in millimeters
• 02Blackriver trucks documented at 29mm, 32mm, 34mm, 36mm — matching Berlinwood width catalog
• 03Axle overhang (truck wider than deck): wheels extend past the deck edge
• 04Inset trucks (truck narrower than deck): wheels sit inside the deck edge
• 05Either configuration is used by some riders — disclose the mismatch in any listing

Many used marketplace listings do not state deck width. Without a measurement, buyers can ask the seller for a caliper or ruler photo across the widest point of the board. Comparing the deck width to truck axle width in photos can also suggest the approximate size, since matched setups commonly show the axle ending near the deck edge. However, visual estimation from photos is not a substitute for a confirmed measurement, and buyers should not assume a width based on appearance alone.^3, 1, 2

• 01Ask the seller for a ruler or calipers photo across the widest point of the deck
• 02Truck axle position relative to deck edge can suggest approximate matching — but is not a confirmed spec
• 03Brand catalogs (Berlinwood, Teak Tuning, DK, etc.) can help narrow down width if the mold or graphic is identified
• 04Do not assume deck width from truck brand alone — the same truck brand offers multiple widths

Retailer and community guides broadly agree that fingerboard widths have trended wider over time. Early boards were narrow — Tech Deck started around 26mm and many early-2000s makers built similarly narrow decks — and 32mm later became the long-standing standard, prized as a balance of control and accessibility. In recent years the community has increasingly moved to 34mm as a modern default, with 33.3–33.6mm treated as a 'sweet spot' in between. These are documented general trends across multiple retailer and community sources, not a precisely dated catalog timeline, and individual rider preference still drives actual width choice — some riders deliberately ride narrower or wider than the current norm.^{7, 1, 16, 8, 2}

• 01Early era: narrow boards (Tech Deck began around 26mm; many early-2000s decks were similarly narrow)
• 0232mm: became the long-standing standard, widely described as a control and accessibility balance
• 0334mm: increasingly the modern default in current pro setups
• 0433.3–33.6mm: commonly described as the 'sweet spot' between 32mm and 34mm
• 05This narrow-to-wide shift is documented across retailer and community guides, but no primary source fixes exact dates — treat it as a general trend, not a precise timeline

When browsing used deck listings on a marketplace, width is the first spec to confirm because it determines truck compatibility and is the hardest dimension to verify without a measurement. Condition, concave, mold, and graphic all matter for deck value, but a deck that cannot be matched with available trucks at the buyer's preferred width is not useful regardless of its other attributes. Buyers who are flexible on width have a broader pool of available listings; buyers who need a specific width should filter or ask early in the conversation.^{10, 3, 1, 8}

• 01Confirm width before evaluating condition — a great-condition deck in the wrong width is not useful
• 0232mm and 34mm are the widths with the most readily available compatible trucks across brands
• 0329mm and 36mm have compatible trucks documented by Blackriver and others but may be harder to find in used listings
• 04Side-by-side photos with a known-width deck or a ruler are more reliable than visual width estimates
