You step up to the line, dart in hand, eyes locked on the bullseye — and someone asks, "Wait, are we even standing in the right spot?" If that question has ever killed your momentum mid-game, you're not alone. A board hung two inches too high or a toe line marked eight inches short quietly wrecks the muscle memory you've spent months building.
Whether you're setting up a basement game room, prepping for a league night, or just finally committing to a permanent installation, this guide covers everything: official dartboard height, regulation throwing distances for both steel-tip and soft-tip darts, the full scoring zone breakdown, wall space requirements, and answers to the questions people ask most.
Every measurement here is cross-referenced against the official standards of the World Darts Federation (WDF), Professional Darts Corporation (PDC), and British Darts Organization (BDO).
What Is the Official Dart Board Height?
The center of the bullseye must be exactly 5 feet 8 inches (173 cm) from the floor.
This is the universal standard. The WDF, PDC, and BDO all agree on this figure — it applies equally to steel-tip and soft-tip formats, amateur home play, and professional tournament stages. The measurement runs from the finished floor surface straight up to the center of the inner bull.
When mounting your board, measure from the floor with a tape measure, not by eye. Mark the wall at 173 cm, hammer your nail, hang the board, then re-verify before fully tightening the bracket. Even a 5 cm deviation from standard is enough to subtly alter your throw arc — and if you ever play competitively, your body will immediately notice a correctly-hung board feels different from your practice board.
A note on surface types: always measure from the finished floor surface you'll be standing on. If you're installing on a raised platform or a thick rubber dart mat, account for that thickness in your floor-to-bullseye measurement. |
Regulation dartboard height for wheelchair players: The BDO specifies a modified standard for players competing from a wheelchair — the bullseye height is lowered to 4 feet 6 inches (137 cm), and the throwing distance is adjusted to 5 feet 9 inches (175 cm). If your game room hosts players who use wheelchairs, designing around the standard height plus a clearly marked alternative oche line makes the space genuinely inclusive.
How Far Do You Stand from a Dartboard? (Throwing Distance)
The throwing distance — measured horizontally from the face of the dartboard to the front edge of the oche (the throwing line) — differs between steel-tip and soft-tip formats.
Steel-Tip Darts
Regulation distance: 7 feet 9.25 inches (237 cm)
This is the standard for all WDF, PDC, and BDO competitive play. It is measured from the face of the board (not the wall) to the front edge of the oche. If your dartboard protrudes 1.5 inches (3.8 cm) off the wall — which is standard for most regulation-thickness boards — your oche mark must sit 7 feet 9.25 inches from the face, meaning approximately 7 feet 10.75 inches from the wall itself.
Soft-Tip Darts
Regulation distance: 8 feet (244 cm)
Soft-tip darts, commonly used with electronic dartboards, are thrown from a slightly greater distance. The National Darts Association (NDA) and most electronic dart leagues standardize this at 8 feet from the face of the board.
Modified Distances for Juniors and Beginners
Official regulations set the same distance for all players in competitive play. However, many recreational leagues and youth programs permit shorter distances. Common alternatives are:
7 feet 6 inches (228.6 cm) — used in some junior leagues
7 feet (213.3 cm) — used for young beginners
These are for informal and developmental play only. If you're practicing with the intention of competing, always train at the regulation distance.
The Diagonal Distance: Your Setup's Best Sanity Check
Here's a number most players never learn but should commit to memory: the diagonal measurement from the center of the bullseye to the front of the oche.
Format | Diagonal Distance |
Steel-tip | 9 feet 7.5 inches (293.4 cm) |
Soft-tip | 9 feet 9.75 inches (approximately 299.2 cm) |
If you measure the diagonal from your bullseye down to your oche and it hits this number precisely, both your height and your throwing distance are correct simultaneously — no need to re-measure each one separately. This is the fastest double-confirmation check you can do after installation.
The diagonal method is also invaluable on uneven floors or when setting up in a basement, where getting a true plumb measurement is difficult. Run your tape from the bullseye center to the oche, nail the measurement, and you're done.
What Size Is a Regulation Dartboard?
A regulation dartboard measures 18 inches (45.7 cm) in diameter — though the more precise figure specified in WDF technical documentation is 17¾ inches (45.1 cm) to the outer edge of the double ring wire. The difference is the wire and surround, which rounds the total to 18 inches in common usage.
Each board also protrudes 1.5 inches (3.81 cm) from the wall or mounting surface — a consistent dimension regardless of brand or model. This is why the throwing distance is always measured from the face, not the wall.
Full Scoring Zone Dimensions
This is the complete breakdown that most guides skip over. These dimensions are standardized across all WDF-regulation boards:
Zone | Inner Diameter | Outer Diameter | Width |
Inner bull (double bull/bullseye) | — | 12.7 mm (0.50 in) | — |
Outer bull (single bull) | 12.7 mm | 31.8 mm (1.25 in) | 9.55 mm |
Inner single field | 31.8 mm | 198 mm (7.79 in) | — |
Triple ring (inner edge) | 198 mm | 214 mm (8.43 in) | 8 mm |
Outer single field | 214 mm | 320 mm (12.60 in) | — |
Double ring (inner edge) | 320 mm | 340 mm (13.39 in) | 10 mm |
Total playable diameter | — | 340 mm (13.39 in) | — |
Total board diameter (incl. wire/surround) | — | 451–457 mm (17.75–18 in) | — |
The 20 segment always sits at the top — the thin black wedge at 12 o'clock. Even a slight rotation of the board misaligns the segment positions for every player who steps up. When mounting, use a level or plumb line to confirm the 20 is perfectly centered at the top.
What Are Dartboards Made Of?
Understanding your board's construction helps you buy right and care for it properly.
1. Sisal fiber is the gold standard material for steel-tip dartboards. Sisal is a natural plant fiber — harvested from the agave plant — that is bundled into tight tubes, compressed, cut into discs, and pressed into the circular form of a dartboard. When a steel dart punctures the fibers, they compress and spring back, which is why quality sisal boards self-heal after use. A well-maintained sisal board from a reputable brand can last for years of regular play.
2. Blade wiring (also called spider wiring) is the wire framework separating the scoring segments. High-quality boards use thin triangular blade wires that angle inward, minimizing the surface area a dart tip can strike — reducing bounce-offs and increasing your scoring percentage. Cheaper boards use round wire, which has a larger contact area and significantly more bounce-offs.
3. Paper and cork boards are still sold, but they do not self-heal. Dart holes become permanent damage, sections tear and delaminate, and the board becomes unplayable relatively quickly. For any serious practice or home setup, sisal is the only sensible choice.
4. Electronic/soft-tip boards use a rigid plastic playing surface with small holes. They're durable in a different way — the surface doesn't wear like sisal — but they require soft-tip plastic darts. Steel darts will permanently damage the surface.
A Brief History of Dartboard Standardization
Darts, as an organized sport, has a surprisingly modern history of regulation.
The game itself is ancient — historical records document dart-throwing as a military pastime in medieval England as early as the 1300s, with soldiers throwing short arrows at upturned wine casks. The modern numbered dartboard — with its distinctive arrangement of high and low numbers around the board to penalize inaccurate throws — was developed in 1896 by Brian Gamlin, a carpenter from Bury, Lancashire, whose clockwise numbering scheme remains unchanged today.
The board's layout is not arbitrary. Placing the 1 and 5 on either side of the 20, and the 3 and 11 flanking the bullseye's neighboring segments, means that missing your intended high-value target in any direction is punished with a low score. It is a design deliberately engineered to reward precision.
Official standardization milestones:
1954 — The British Darts Organization (BDO) formally codifies the regulation height (5'8") and throwing distance (7'9.25") that all major bodies still use today
1976 — The British Darts Organization is founded and takes over the standardization of competitive rules in the UK
1993 — The World Darts Federation (WDF) becomes the primary international governing body for the sport
2001 — The Professional Darts Corporation (PDC) establishes its own independent tour, though using identical measurement standards
2005 — Darts is officially recognized as a sport by Sport England
All three governing bodies — WDF, PDC, and BDO — have independently arrived at and maintained identical measurement standards for the height (5'8") and steel-tip throwing distance (7'9.25"). That unanimity across rival governing bodies, sustained for over 70 years, is strong evidence that these measurements represent a genuine optimum for the sport.
Quick Reference: All Regulation Measurements
Measurement | Steel-Tip | Soft-Tip |
Bullseye height from floor | 5 ft 8 in / 173 cm | 5 ft 8 in / 173 cm |
Throwing distance (from board face) | 7 ft 9.25 in / 237 cm | 8 ft / 244 cm |
Diagonal (bullseye to oche) | 9 ft 7.5 in / 293.4 cm | 9 ft 9.75 in / 299.2 cm |
Board diameter (playable) | 13.39 in / 340 mm | 13.39 in / 340 mm |
Board diameter (total) | ~18 in / 457 mm | ~18 in / 457 mm |
Board protrusion from the wall | 1.5 in / 3.81 cm | 1.5 in / 3.81 cm |
Clearance on each side of the board | 2 ft / 61 cm minimum | 2 ft / 61 cm minimum |
How Much Wall Space Do You Need?
A dartboard setup needs more room than the board itself. Here are the practical space requirements for a safe, comfortable installation:
Horizontal clearance: At minimum, 2 feet (61 cm) on each side of the board's center — roughly 5 feet of total horizontal space. For a proper game room setup where multiple players can stand comfortably, plan for at least 5 feet on each side (10 feet total width).
Vertical clearance: 3 feet of clear wall above the bullseye, and the full 5 feet 8 inches below it to the floor — that's roughly 8 feet 8 inches of total vertical clear space. In practice, a standard 8-foot ceiling works fine.
Room depth: From the wall to the back of the oche, plan for at least 11 to 12 feet. This provides a comfortable throwing room and enough space for a second player to stand back from the throwing line.
Protecting your walls: Stray darts happen. Options include a dartboard surround (a foam ring around the board that catches errant darts), a dartboard cabinet (a wooden housing that fully encloses the board and opens for play), or a designated backing of corkboard, dense foam, or a sisal panel behind and around the board. A surround is the most cost-effective solution and the standard choice in game rooms.
How to Mark Your Throwing Line (The Oche)
"Oche" (pronounced "ockey") refers to the throwing line — the boundary players' feet must not cross during a throw. Players may lean their body and arm beyond the line, but the front foot must remain behind it.
Several options for marking it:
Painter's tape is the easiest starting point. Removable, cheap, and easily adjusted while you're still dialing in your setup distance. Not durable long-term.
Rubber or PVC oche strips are purpose-built for darts setups. They sit flat on the floor, provide a tactile reference for your foot, and are durable enough for permanent use. Most are 18–24 inches wide and about 1 inch thick — enough to feel underfoot without creating a trip hazard.
Inlaid wood or tile strip is the premium option for a finished game room. A strip of contrasting hardwood or tile built flush into the flooring is permanent, clean, and immediately communicates seriousness to anyone who walks into the room.
Dart mat is the all-in-one solution — a rubber mat that typically runs from the board to well beyond the oche, with the oche line marked on the mat itself. It protects the floor from dropped darts, cushions bounced darts, and marks the line in one product.
Frequently Asked Questions
1. How high should a dartboard be mounted?
The center of the bullseye should be exactly 5 feet 8 inches (173 cm) from the floor. This is the universal standard used by the WDF, PDC, and BDO for all levels of play.
2. How far do you stand from a dartboard?
For steel-tip darts, the throwing distance is 7 feet 9.25 inches (237 cm) measured from the face of the board to the front of the oche. For soft-tip/electronic darts, the standard distance is 8 feet (244 cm).
3. What is the size of a regulation dartboard?
A regulation dartboard has an outer diameter of approximately 18 inches (457 mm). The playable scoring area (to the outer edge of the double ring) measures 13.39 inches (340 mm) in diameter. The inner bull is 12.7 mm in diameter; the outer bull measures 31.8 mm.
4. What is the oche in darts?
The oche (pronounced "ockey") is the throwing line in darts — the boundary players must not step over when throwing. It can be a raised platform, a rubber strip, or a line marked on the floor. In regulation play, it sits 7 feet 9.25 inches from the face of the board for steel-tip darts.
5. Is the dartboard distance different for soft-tip darts?
Yes. Steel-tip darts are thrown from 7 feet 9.25 inches (237 cm). Soft-tip darts are thrown from 8 feet (244 cm). The bullseye height of 5 feet 8 inches (173 cm) remains the same for both.
6. Can I mount a dartboard lower for children or beginners?
Officially, competitive play requires a standard height of 5 feet 8 inches for all players. For informal home play with young children, some parents lower the board and shorten the throwing distance. A common starting point for younger children is 4 feet 6 inches for the bullseye and 5 to 6 feet for the throwing distance, with these gradually increasing as they develop.
7. What is the diagonal measurement for a dartboard setup?
The diagonal distance from the center of the bullseye to the front of the oche is 9 feet 7.5 inches (293.4 cm) for steel-tip darts. This measurement simultaneously confirms both the correct height and throwing distance — if the diagonal is right, the full setup is right.
8. Do all dartboard governing bodies use the same measurements?
Yes. The WDF (World Darts Federation), PDC (Professional Darts Corporation), and BDO (British Darts Organization) all specify identical regulatory measurements: a 5-foot-8-inch bullseye height and a 7-foot-9.25-inch throwing distance for steel-tip darts. This standard has been consistent since the BDO first codified it in 1954.
Setting Up Right Means Playing Right
The measurements above aren't bureaucratic formalities — they represent over 70 years of consensus between every major darts organization on the planet. When your board is hung at 5 feet 8 inches and your oche sits at 7 feet 9.25 inches, your practice is directly transferable to every bar, league venue, and tournament floor you'll ever throw on. Your muscle memory builds on geometry that travels with you.
At MaximillianoGameroom.net, we believe a game room built correctly is one that actually gets used. Hang your board, mark your line, and start throwing as it matters — because when the setup is right, every practice session does.
