Understanding standard field dimensions is crucial for the planning and construction of indoor futsal courts, facilitating construction and determining the required dimensions and quantity of sports flooring materials, thus better controlling costs. Based on FIFA official regulations and industry experience, this document breaks down the standard dimensions of indoor futsal courts (including both meter and foot units) and details of each functional area for reference.
The dimensions of indoor futsal courts are not fixed but fall within a defined range (length 25 to 42 meters, width 15 to 25 meters), and must meet two core conditions:
① The length must be at least 2 meters longer than the width;
② The width must not be less than half the length.
Based on FIFA's "Rules of Futsal" and practical scenarios, dimensions can be categorized into "Standard Dimensions for Professional Matches" and "Dimensions Adapted to Practical Scenarios" for users with different needs.

Core Dimensions: Length 40 meters (131.23 feet) × Width 20 meters (65.62 feet), with an allowable error of ±2 meters (i.e., minimum 38 meters × 18 meters, maximum 42 meters × 22 meters);
Key Verification: 40 meters (length) - 20 meters (width) = 20 meters ≥ 2 meters, 20 meters (width) = 40 meters (length) × 50%, fully meeting the size restrictions;
Details of Each Functional Area (accurate to centimeters/inches):
Goal Area: Extends 5.8 meters (19.03 feet) from the goal line into the field, with a width of 11 meters (36.09 feet), forming a rectangular penalty area. A foul within this area will result in a penalty kick;
Penalty Spot: 6 meters (19.69 feet) from the goal line. 1.2 Practical Field Size
For non-professional sports settings such as school gymnasiums, community activity centers, commercial leisure venues, and home training areas, the size can be flexibly adjusted according to the available space, but the core requirement is to meet the range of "length 25-42 meters, width 15-25 meters".
Penalty Arc: An arc with a radius of 8 meters (26.25 feet) centered on the penalty spot. All players except the penalty taker and goalkeeper must be outside the arc.
Corner Flag Area: A fan-shaped area with a radius of 1 meter (3.28 feet) at each corner for placing corner flags. Corner kicks must be taken from within this area.
Field Lines: All lines are 5 centimeters (1.97 inches) wide, white (or a color that contrasts sharply with the field), and within the field boundaries.
For non-professional sports settings such as school gymnasiums, community activity centers, commercial leisure venues, and home training areas, the size can be flexibly adjusted according to the available space, with the core requirement being a range of "length 25-42 meters, width 15-25 meters".
School/Community General Size: Length 30 meters (98.43 feet) × Width 15 meters (49.21 feet)
Verification: 30-15=15 meters ≥ 2 meters, 15 meters = 30 meters × 50%, meets the requirements; suitable for 150-200 people using simultaneously, accommodating basketball, badminton, and other multi-purpose needs.
Home/Small Training Size: Length 25 meters (82.02 feet) × Width 15 meters (49.21 feet)
Verification: 25-15=10 meters ≥ 2 meters, 15 meters = 25 meters × 60% ≥ 50%, meets the requirements; suitable for villa courtyards, small gyms, meeting family entertainment or training for up to 10 people.
Commercial Multi-Purpose Size: Length 35 meters (114.83 feet) × Width 20 meters (65.62 feet) (feet)
Verification: 35-20=15 meters ≥ 2 meters, 20 meters = 35 meters × 57.1% ≥ 50%, meeting the restrictions; allows for quick switching between five-a-side football, basketball, and volleyball scenarios, improving field utilization.
Goal Dimensions: Standard goal height 2 meters (6.56 feet) × width 3 meters (9.84 feet), goal frame material is steel pipe (thickness ≥ 3mm), inner side must be wrapped with impact-resistant foam (thickness ≥ 5cm) to prevent player injuries from collisions;
Indoor clearance height: Core requirement ≥ 4.5 meters (14.76 feet), professional competition venues recommend ≥ 5 meters to prevent players from hitting the top when jumping; if the field is located underground or on a floor, it is necessary to confirm in advance that the floor load-bearing capacity ≥ 1000kg/㎡ to meet the weight requirements of players and equipment.
PVC sports flooring is the mainstream choice for indoor five-a-side football fields (accounting for over 80%). Its core advantages are slip resistance, wear resistance, good cushioning performance, and easy installation and low maintenance costs.
| Venue type | Site Size (m) | Recommended PVC flooring type | Floor Specification (Thickness / Size) | Core adaptation reasons |
| Professional event venues | 40×20 | Adhesive PVC sports flooring | 6-8mm thick, coil (1.8m/2m wide) | Seamless splicing avoids dirt contamination, and the wear-resistant layer ≥ 0.5mm, which is resistant to high-intensity use in events |
| School/community venues | 30×15/35×20 | Locking PVC sports flooring | 4.5-6mm thick,tiles(50cm×50cm) | It is easy to install (2 people can lay 100㎡ in 1 day) and supports multi-purpose switching |
| Home training area | 25×15 | Lightweight lock floor | 3-4.5mm thickness,tiles(30cm×30cm) | Good cushioning to protect joints, DIY installation and flexible storage |
| Commercial multi-purpose venues | 35×20 | Customized PVC coils | 5-6mm thick, coil (2m wide, can be pre-printed with field wire) | Printable LOGO and multi-sport venue lines to improve utilization |
When purchasing PVC flooring, try to match the flooring specifications to the site dimensions in an "integer multiple" to reduce cutting waste:

Roll Flooring: If the site width is 20 meters, prioritize 2m wide rolls (20 ÷ 2 = 10, no remainder), with the length calculated based on the site length plus wastage; if the site width is 15 meters, choose 1.8m wide rolls (15 ÷ 1.8 ≈ 8.33, requiring 0.33m to be cut, with relatively controllable waste);
Modular Interlocking Tiles: If the site size is 30 × 15 meters, choose 50cm × 50cm tiles (30 ÷ 0.5 = 60 tiles, 15 ÷ 0.5 = 30 tiles, no cutting waste); if the site size is 25 × 15 meters, choose 30cm × 30cm tiles... Tiles (25 ÷ 0.3 ≈ 83.33, 15 ÷ 0.3 = 50, 0.03m needs to be cut).
Additionally, the dimensions of futsal court flooring are generally larger than the actual court area, including areas outside the court lines.
For example, if the total length and width of the court is 40 × 20m, then the required flooring dimensions are 44 × 24m.
For futsal, 8mm PVC flooring thickness is recommended.
Abrasion layer thickness: Professional competitions ≥ 0.5mm (PUR material is best), schools/communities ≥ 0.3mm, residential ≥ 0.2mm (directly determines lifespan);
Sports performance: Ball rebound rate ≥ 85%, impact absorption rate ≥ 20% (supplier must provide test reports), avoid purchasing ordinary PVC flooring not designed for sports;
Environmental certification: Must pass EU REACH, US FloorScore, or domestic E0 certification, VOC emissions ≤ 0.08mg/m³, ensuring indoor safety.
Plan the Laying Sequence in Advance: Start from one corner of the field and lay along the long side, concentrating the cut edges at the field's edge as much as possible (which can be covered by edge trim later);
Pre-treatment of Irregularly Shaped Areas: If the field has pillars or obstacles, measure the dimensions in advance and draw cutting diagrams, cutting precisely according to the diagrams to avoid blind cutting;
Select the Matching Flooring Type: For regular fields, prioritize roll flooring (low wastage rate); for irregular fields, prioritize click-lock tiles (flexible cutting, controllable wastage).
Substrate Treatment: Ensure the ground is flat (flatness error ≤ 2mm/2m) and dry (moisture content ≤ 8%), otherwise it will cause the flooring to warp and become hollow;
Expansion Joint Provision: Regardless of whether it is roll flooring or tiles, a 5-8mm expansion joint should be reserved around the perimeter of the field (to cope with thermal expansion and contraction caused by temperature changes);
Field Line Treatment: For professional competitions, it is recommended to choose PVC flooring with "pre-printed field lines" (high precision, wear-resistant); for ordinary fields, professional sports floor paint can be applied later (line width 5cm, requiring masking tape for positioning).
