Choosing a tournament venue

Competition area

The competition floor is the starting point. Calculate how much mat or court area you need based on your format and participant count, then confirm the venue can accommodate it.

For combat sports with mat-based competition (judo, wrestling, taekwondo), each active mat or court requires a competition area plus a surrounding safety zone. For judo, the contest area at IJF international level is 10×10 metres with a 3-metre safety zone on each side — 16×16 metres total per mat. National and regional events typically use an 8×8 metre contest area (14×14 total); local club competitions with youth categories often use 6×6–8×8 metres depending on age group and federation rules. A standard WT taekwondo court is 8×8 metres with at least 1 metre safety zone — 10×10 metres minimum total. Two mats side by side with a shared safety buffer require approximately 22–28 metres of floor width depending on the sport and level.

Floor surface matters. Mats must be placed on a flat, level surface without gaps. Some venues have raised platforms or uneven joins between floor sections that are incompatible with mat placement. Always inspect the floor in person before booking.

Ceiling height is relevant for sports with throws or high kicks. A minimum of 6 metres clear height is recommended for most combat sports. Lower ceilings are rarely a safety issue but can restrict technique near the edges of the mat.

How many mats do you need?

The number of active mats is the single biggest lever on event duration. Adding a mat roughly halves the remaining schedule time during early rounds. Removing a mat doubles it. Getting this number right before you book the venue is essential.

A practical starting point: one mat can handle approximately 7–10 match slots per hour in judo (allowing 5–6 minutes average match time plus 1–2 minutes changeover). Events with a mix of age groups — where younger categories use shorter match times and pool formats — can run faster, pushing closer to 10 or more slots per hour. In taekwondo, where senior bouts run three fixed two-minute rounds, expect 6–7 slots per hour per court.

A reliable rule of thumb for national and larger events: plan for 50–80 athletes per mat for a full competition day. The range depends on the mix of age categories and formats — a pure senior event with 4-minute bouts sits closer to 50, while an event mixing U9–Senior with pool formats can accommodate up to 80 per mat. As a worked example: a 500–550 athlete national event running age groups from U9 to Senior, with roughly half the field in pools, is manageable on 5 mats in an 8-hour day.

Too few mats means athletes wait hours between bouts, spectators lose interest as the event drags on, and the schedule inevitably overruns. Officials fatigue faster when a single mat runs continuously all day without rotation.

Too many mats creates less obvious but equally real problems. In judo and most combat sports, athletes are guaranteed a minimum rest period between bouts. If you have more mats than the field can sustain, mats end up standing idle — not because athletes have all competed, but because athletes are still in their mandatory rest window and cannot be called. Pushing athletes onto the mat before they have had sufficient rest is not permitted, so the extra mat capacity simply goes unused. On top of this, the field narrows in later rounds anyway, requiring consolidation to one or two mats for semi-finals and finals regardless of how many mats ran in early rounds. More officials are needed to manage more mats, and the event can feel disorganised if large sections of the competition floor are empty.

Use the bracket calculator to work out your total match count and experiment with different mat counts before committing to a venue booking.

Approved mats and flooring

Not all mats are suitable for all competition levels. Governing bodies maintain approved equipment lists, and using non-approved mats at a sanctioned event can result in the event losing its licensed status.

For judo, the IJF maintains a list of approved tatami. Approved mats must meet specific requirements for firmness, shock absorption, and surface friction. At IJF international events, only mats from the approved list may be used. National federations typically maintain their own approved lists for domestic events, which may include additional brands. For club and local events, the requirements are generally relaxed — but confirm with your national federation what is required for the event category.

For taekwondo kyorugi, World Taekwondo specifies approved flooring for sanctioned events. The surface must provide adequate grip and shock absorption for kicking techniques. At club level, standard sports hall flooring with temporary mat sections is often acceptable — again, check with your national federation.

Mat colour coding is also standardised at higher levels. In judo, the contest area is typically yellow with a blue surrounding safety zone. Athletes and referees use the colour boundary as a visual indicator of the contest area edge. For local events, clearly marking the contest area boundary — even with tape — is important for athlete safety.

If the venue does not have its own mats, confirm whether you need to transport and assemble them. Mat transport requires a suitable vehicle and sufficient crew — a full-size judo mat (typically assembled from individual 1×1 or 1×2 metre tatami tiles) is heavy and awkward to move. Laying the mats alone may take 60–90 minutes, but being fully ready to receive athletes — tables set up, scoreboard connected, weigh-in station prepared, officials briefed — requires considerably more time. Allow a minimum of 3–4 hours before the first athlete is due for a smaller club event. Larger regional or national events typically require a full day of setup the day before, and major international competitions may need several days of venue preparation.

Warm-up and preparation space

Athletes need space to warm up before their bouts. For events with repechage, an athlete may have two or three bouts across the day and needs to warm up before each one. A warm-up area that is too small creates congestion and safety risks.

As a rule of thumb, budget warm-up space equivalent to one additional mat area for every two active competition mats. This does not need to be a dedicated room — a clear section of the main hall behind the spectator area works if the space is genuinely usable and mat-covered.

Coaches need to be able to observe the competition from the warm-up area or have a clear path to the mat-side seating. Venues where the warm-up space is completely separated from the competition floor make it difficult for coaches to manage athlete preparation and timing.

Changing rooms

Changing room capacity is one of the most commonly underestimated requirements. Calculate your peak load: the number of athletes who may need to change simultaneously at the start of the event.

For a 100-person event with 50 male and 50 female athletes, you need enough changing space for at least 30–40 people per gender at peak (not everyone arrives at the same time, but the first 90 minutes are typically busy). A single changing room with 10 benches is not enough.

Changing rooms should be close to the competition floor — athletes in competition kit walking long corridors or across other areas of a facility is a common cause of delays. Separate access routes for athletes and spectators are ideal.

Shower availability matters for longer events. For a full-day competition where athletes may compete across the morning and afternoon, shower access significantly improves athlete experience. Confirm whether showers are available and whether they are included in the venue hire.

Spectator capacity

Spectator numbers are easy to underestimate. Tournament size varies considerably: club championships and smaller local events typically attract 50–120 athletes; smaller national events 120–240; mid-size opens 240–450; and large national or international events can bring 450 to over 1 500 athletes. For any of these, expect 2–4 spectators per athlete — coaches, family members, and teammates not competing. A club event with 80 athletes may have 200–300 people in the venue simultaneously. A sports hall sized for the mat area alone is not adequate.

Spectators need a clear sightline to at least the main competition mat. Venues where the spectator area is behind a wall or where sightlines are blocked by pillars frustrate visitors and coaches. Walk the venue from a spectator position, not just an organiser position.

If you expect media or a livestream setup, identify where cameras can be positioned with a clear elevated angle. This usually requires a raised seating section or a balcony. Confirm that power outlets are accessible from those positions.

Technical requirements

Modern tournament operations require reliable power and connectivity. Confirm the following with the venue before booking:

• Power outlets at mat-side: Each active mat needs at least one outlet for scoreboard, electronic scoring equipment, or a laptop. Extension leads across walkways are a trip hazard.
• Sound system: A working PA system covering the full competition floor is essential for calling up athletes and making announcements. Test it at the venue walk-through — many sports hall PA systems are poor quality or have dead zones.
• Wi-Fi or mobile connectivity: If you are using digital bracket management, scoreboard displays, or livestreaming, confirm network coverage at the competition floor — not just the lobby.
• Scoreboard displays: Large-screen displays visible from the spectator area improve the experience significantly. Confirm whether the venue has displays and whether they can be connected to your scoring system.
• Lighting: Competition areas need bright, even lighting without shadows across the mat. Side-lit halls with windows can create glare problems for athletes and referees at certain times of day.

Logistics and access

The practical logistics of getting people and equipment to the venue are easy to overlook when focused on the competition itself.

• Parking: Estimate parking demand based on your expected attendance. If on-site parking is limited, identify nearby public parking and include directions in your participant communication. Lack of parking is one of the most common complaints from athletes and spectators at smaller events.
• Public transport: Note the nearest bus or rail stops and walking distance in your event bulletin. For athletes travelling from other regions, clear transport information removes friction and reduces late arrivals.
• Equipment access: Confirm there is a loading entrance or wide corridor for delivering mats, scoring equipment, and supplies. Sports halls on upper floors with only a passenger lift create real logistical problems.
• Setup time: Negotiate venue access from at least 2–3 hours before the first athlete is due to arrive. Mat setup, scoreboard positioning, weigh-in station, and table layout all take longer than expected. A venue that only allows access from 30 minutes before the event starts will cause a delayed opening.
• Teardown time: Book the venue until at least 90 minutes after your scheduled finish. Running over is common, and needing to rush teardown while athletes and spectators are still present creates confusion.

Catering and facilities

Food and drink availability affects athlete performance and overall event experience. A full-day event with no food options on site will see athletes and families leave the venue during breaks, creating re-entry bottlenecks and scheduling problems.

Options in order of effort: confirm the venue has an on-site canteen or café, arrange a food vendor to set up for the day, or identify nearby restaurants and include them in your participant guide. At minimum, ensure drinking water is freely available at the competition floor at all times.

First aid provisions are a requirement, not an option. Confirm the venue has a first aid room or identify a space you can use. Ensure you have at least one qualified first aider present throughout the event. Check your governing body's rules — some federations require a specific level of medical provision for licensed events.
