Equipment Specifications

The cage / ring

The Unified Rules permit either a cage or a ring, with specifications:

Cage (the UFC Octagon and equivalents):

• 6 to 8 sides (the UFC Octagon has 8).
• 30 feet across between opposing sides (the UFC Octagon dimension).
• 6-foot tall fencing; the UFC Octagon fence is made of vinyl-coated chain link.
• Cage floor is canvas-covered foam, similar to a boxing ring but typically less padded.

Ring (PRIDE-style, used by RIZIN):

• Square or rectangular with ropes.
• 20 to 24 feet square (PRIDE's ring was 24 feet).
• Three or four ropes around the perimeter.
• Canvas-covered foam floor.

The UFC's Octagon is trademarked. Other cage designs (hexagonal Bellator cage, circular Cage Warriors cage) are permitted under the Unified Rules and have been used by various promotions.

Gloves

The Unified Rules specify open-finger MMA gloves:

• Weight: 4 to 6 ounces. Lighter than boxing gloves (10-12 oz). The lighter weight allows the grappling and gripping that MMA requires.
• Construction: padded over the knuckles; open across the fingers and palm to permit gripping; thumb attached to the glove body for grappling safety.
• Brand: UFC uses a proprietary glove designed by Joe Silva (former UFC matchmaker) in the early 2000s. Other promotions use various brands (Bellator's brand, RIZIN's brand).

The 2024 glove redesign: in late 2024, the UFC introduced a redesigned glove with a slightly different padding distribution after years of complaints about eye-poke risk from the splayed-finger design. The new gloves have a more curled finger position by default, which reduces the inadvertent eye-poke incidence by an estimated 20-30%. The redesign was the result of multiple high-profile eye-poke incidents (Khabib-vs-Iaquinta, Reyes-vs-Jones at UFC 247) and represents the first major glove change in over two decades.

Hand wraps

Required underneath the gloves. Specifications:

• Material: gauze and tape, or fabric wraps. Most fighters use fabric wraps for the bulk of the wrap with gauze and tape over the knuckles.
• Length: typically 12-15 feet of wrap material per hand.
• Inspection: wraps are inspected and signed by an athletic commission representative before the gloves are placed over them. Tampering with wraps after inspection is a fineable offense.

Famous wrap-related controversies:

• Antonio Margarito (boxing, 2009): caught with plaster-loaded wraps before his Shane Mosley bout. While this is boxing, the inspection protocol that detected the violation was subsequently tightened across combat sports.
• The 2009 UFC wrap-tape controversy: the UFC moved to standardized wrap inspection protocols after several disputed cases.

Mouthguard

Required for both fighters. Specifications:

• Custom-fitted preferred: most professional fighters use custom-molded mouthguards.
• Generic boil-and-bite accepted: lower-tier amateur and regional events accept commercial mouthguards.
• Color is regulated in some commissions: red, white, and blue mouthguards may be restricted in commissions that require distinctive corner colors (red corner / blue corner).

Mouthguard loss during a bout is a foul if the loss is intentional (timidity). Repeated unintentional loss can produce a referee warning.

Cup / groin protection

Required for male fighters. Specifications:

• Hard cup with strap or sleeve: the standard combat sports cup.
• Inspection at weigh-in: most commissions inspect the cup at weigh-ins to ensure compliance.
• Female fighters: cup is optional; many female fighters use chest protection instead.

Female fighters can opt to wear a chest protector but are not required to. Some commissions require it; most leave it optional.

Knee and ankle protection

Not permitted in any combat sports rule set. Knee braces, ankle braces, athletic tape over braces are prohibited. The historical reason: any rigid material over a joint can be weaponized in a strike. Fighters with knee or ankle injuries either compete without protection or withdraw from the bout.

Apparel

• Shorts: knee-length or shorter. Cannot have pockets, snaps, zippers, or hard buckles. Standard MMA shorts are nylon with Velcro waist closures.
• No shirts permitted for men: rare in unified-rules MMA; the policy dates to the early UFC era.
• Sports bras for women: standard. Athletic tape over a sports bra to secure it is permitted.
• No jewelry: rings, necklaces, earrings, watches all prohibited. Religious-medallion exemptions occasionally granted with athletic commission approval.

Pre-fight medicals

The Unified Rules require pre-fight medical examinations:

• Blood test panels: HIV, Hepatitis B and C, plus full blood counts. Required annually or per fight (commission-dependent).
• Eye examination: detached retina history is a disqualifying factor in most commissions.
• Neurological examination: post-concussion suspension protocols include neurological clearance before the next bout.
• Day-of weigh-in medical: vital signs, hydration check, post-cut assessment.

Post-fight medicals

• Immediate KO/TKO assessment: ringside physician examines the recipient of any KO or TKO finish.
• 30/60/90-day suspensions: any KO triggers an automatic 30-day medical suspension at minimum. TKOs from accumulated damage typically receive 60-90 day suspensions.
• CT scan requirement: severe KO cases require a CT scan before the next bout. The Nevada commission is the strictest; some smaller markets are looser.

Cage doctor / cut man

• Cage doctor (ringside physician): licensed physician with combat sports training. Examines fighters between rounds and after the bout.
• Cut man: contracted by the fighter's camp to manage cuts and swelling during the bout. Famous cut men: Jacob "Stitch" Duran, Jorge Klein. The cut man is part of the corner crew but is independently inspected and approved by the commission.

What's NOT regulated

• Diet and pre-fight nutrition: completely unregulated. The historical absence of weight-cut regulation has produced documented deaths (Yang Jian Bing 2015, Leandro Souza 2013, Rondel Clark 2017).
• In-cage strategy and pace: no rule mandates aggression; fighters can play defensively if they choose, subject only to "timidity" warnings from the referee.
• Pre-fight psychology / mental health screening: not required, but some commissions ask basic questions during the pre-fight medical.

The trajectory

Equipment regulation in MMA has moved slowly. The Unified Rules' 2001 specifications are largely unchanged 24 years later, with the notable exceptions of:

• The 2024 glove redesign.
• The 2017 grounded-fighter clarification.
• The 2024 12-to-6 elbow legalization.

The next regulatory frontier — weight-cut safety, mental health screening, federation-level oversight — has not produced consensus changes yet.
