Football Specifications & Spec Sheet Reference
Direct factory reference guide for wholesale procurement, OEM spec-sheeting, panel construction, and international certification standards (FIFA Quality Pro, FIFA Quality, IMS).
Standard Football Sizing & Physical Weight Tolerances
Navigating commercial football procurement requires precise specification sheets. At SportSanga’s Sialkot manufacturing facility, all production runs adhere strictly to official FIFA international weight, pressure, and circumference tolerances. Below is our engineering baseline for bulk production.
| Ball Category | Circumference | Weight Tolerance | Working Pressure | Target Age / Discipline |
|---|---|---|---|---|
| Size 5 (Official Match) | 68.0 – 70.0 cm | 410 – 450 g | 0.8 – 1.1 bar (11.6 – 16.0 psi) | Adults, Seniors & Youth U13+ |
| Size 4 (Junior Match/Training) | 63.5 – 66.0 cm | 350 – 390 g | 0.6 – 0.8 bar (8.7 – 11.6 psi) | Youth U9 through U12 |
| Size 3 (Junior Development) | 58.0 – 60.0 cm | 300 – 320 g | 0.6 – 0.8 bar (8.7 – 11.6 psi) | Children U8 & Skills Training |
| Futsal Size 4 (Low-Bounce) | 62.0 – 64.0 cm | 400 – 440 g | 0.6 – 0.9 bar (8.7 – 13.0 psi) | Indoor Court Play (Low Rebound 50-65cm) |
| Size 1 & 2 (Promotional / Mini) | 46.0 – 52.0 cm | 180 – 240 g | 0.4 – 0.6 bar (5.8 – 8.7 psi) | Souvenir, Club Promo & Reflex Drills |
International Performance Certification Standards
When specifying balls for professional leagues, school tenders, or retail distribution, technical compliance determines acceptance. SportSanga manufactures to match the four primary certification tiers:
FIFA Quality Pro
The highest international benchmark for professional match balls used in top-tier league play.
- Weight: 420 – 445 g
- Water absorption: < 10% weight increase
- Rebound: 135 – 155 cm (dropped from 2m at 20°C)
- Loss of pressure: Max 10% after 3 days
FIFA Quality / IMS
International Match Standard (IMS) designed for official club matches and high-level training equipment.
- Weight: 410 – 450 g
- Water absorption: < 15% weight increase
- Rebound: 125 – 155 cm (dropped from 2m)
- Shape retention: 2,000 shoots test at 50 km/h
Club Training Grade
High-durability construction built to survive multi-season rotation on artificial turf and natural grass.
- Weight: 410 – 440 g
- Reinforced multi-layer backing
- High-retention butyl bladder
- Scratch-resistant TPU outer shell
Panel Architecture & Stitching Methodologies
Selecting the correct assembly technique depends on your target market, price point, and play conditions. Our Sialkot plant runs three distinct production technologies under one roof:
Thermo-Bonded Construction
Seamless thermal sealing technology eliminates water absorption and ensures perfectly spherical flight trajectories.
- Zero water uptake during wet weather play
- Smoother aerodynamics and uniform surface feel
- Ideal for premium tournament match balls
- 14, 18, or 32-panel modern configurations
Hand-Stitched Craftsmanship
Sialkot’s world-renowned hand-stitching legacy. High tensile 5-ply polyester thread locked with deep needle tension.
- Extreme seam durability and tension memory
- Deeply recessed seams reduce aerofoil drag
- Ideal for traditional match and club balls
- 32-panel classic pattern geometry
Hybrid (Dual-Connection)
Combines machine stitching with heat-activated seam sealant gel for a cost-effective, water-resistant training ball.
- Concealed stitching protected from abrasion
- Enhanced shape retention versus standard machine stitching
- Excellent balance of price and performance
- Preferred choice for school and academy bulk supply
Outer Casing Materials & Inner Bladder Core Matrix
Raw material selection dictates hand-feel, cold-weather flexibility, and long-term air retention. We provide complete material transparency for OEM specification sheets.
| Component Layer | Material Option | Performance Characteristics | Best Suited For |
|---|---|---|---|
| Outer Shell | Japanese Microfiber PU (1.2mm - 1.5mm) | High elasticity, superior grip texture, anti-abrasion finish, soft touch in freezing conditions. | Official FIFA Quality Pro Match Balls |
| Outer Shell | Korean TPU (0.15mm film + POE Foam) | High durability, excelente scuff resistance, vibrant color reproduction for custom graphics. | Club Match & Premium Training Balls |
| Outer Shell | Durable PVC (1.6mm - 2.5mm) | High surface hardness, resistant to concrete/gravel abrasion, highly economical. | Promotional & Entry-Level Street Balls |
| Backing Matrix | Provides structural shape stability, preventing ballooning under intense impact. | Hand-Stitched Match Balls | |
| Backing Matrix | 2.5mm - 4.0mm High-Rebound EVA / POE Foam | Delivers responsive cushioning, dampening foot impact while maintaining high energy return. | Thermo-Bonded & Hybrid Balls |
| Bladder Core | Taiwan High-Retention Butyl Bladder | Air leak rate < 3% per month. Maintains pressure over weeks without re-pumping. | Training Balls & Commercial Club Supply |
| Bladder Core | Reinforced Natural Latex Bladder | Provides linear rebound acceleration and soft elite touch. Requires regular pumping. | Professional Stadium Match Balls |
