1. Tennis Racket Head Size (95–105 sq.in.) & Unstrung Weight OEM Chart
Under International Tennis Federation (ITF) equipment rules, adult tennis rackets operate within a standard 27-inch (685.8mm, or extended 694mm) length, 22mm–26mm aero-box beam thickness, and 320mm–335mm unstrung balance point. Selecting the right head size—from 95–98 sq.in. tour frames to 100 sq.in. modern spin benchmarks and 102–105 sq.in. oversize club frames—paired with 260g–300g unstrung mass defines your brand's target player segment.
Key Takeaways for Tennis & Squash OEM Buyers:
- Tennis Head Size & Weight (95–105 sq.in., 260–300g): 96–98 sq.in. frames (UN-TN-02, 295–300g) target tour precision; 100 sq.in. frames (UN-TN-01 / UN-TN-03, 275–285g) represent the global commercial sweet spot; 105 sq.in. oversize molds (UN-TN-04, 260–270g) maximize club forgiveness.
- Tennis String Pattern & Tension (16×19 vs 18×20, 45–62 LBS): Open 16×19 patterns dominate 82% of OEM retail orders by increasing main-string snapback and topspin RPM at 52–62 LBS recommended tension.
- Squash Head Size & Throat (72.5–78 sq.in. / 468–503 cm², 160–195g): Closed-throat bridged frames (UN-SQ-01/02, 72.5–77.5 sq.in.) maximize torsional control on tight rail shots, while Open-throat teardrop frames (UN-SQ-03, 76–77.5 sq.in.) lengthen main strings for explosive power.
- Squash String Bed & Low MOQ (14×18 vs 16×19, 24–28 LBS): Strung at 24–28 LBS, 14×18 and 16×17 beds enhance ball bite and cut, whereas 16×19 increases string durability for club fleets; private-label MOQ starts at 100 pcs per model.
| OEM Platform SKU | Head Size (sq.in. / cm²) | Unstrung Weight & Balance | String Pattern & Tension | Target B2B Market Segment |
|---|---|---|---|---|
| UN-TN-01 (100 sq.in. Pro Spin) | 100 sq.in. (645 cm²), 685±2mm | 280–285g (±3g) / 325mm Balance, 23–25mm Beam | 16 × 19 Open Spin (45–60 LBS / Max 62 LBS) | Flagship all-court club & tournament retail bestseller |
| UN-TN-02 (96 sq.in. Tour Control) | 96 sq.in. (619 cm²), 685±2mm | 295–300g (±3g) / 320mm Head-Light, 22mm Box Beam | 16 × 19 Tour Density (50–62 LBS) | Advanced competitive players & pro-shop control line |
| UN-TN-03 (100 sq.in. Intermediate) | 100 sq.in. (645 cm²), 685±2mm | 270–275g (±3g) / 330mm Even Balance, 24mm Aero Beam | 16 × 19 High-Launch (45–60 LBS) | Intermediate adults, rising juniors & women's club series |
| UN-TN-04 (105 sq.in. Oversize Power) | 105 sq.in. (677 cm²), 685 / 694mm | 260–268g (±3g) / 335mm Head-Heavy, 26mm Wide Beam | 16 × 19 Sweet-Spot Expand (45–58 LBS) | Recreational beginners, senior doubles & resort rental fleets |
Regional Grip Size Standardization (G1 vs G2 vs G3):
For Asian distributions, 75% of adult tennis OEM orders specify G2 (4 1/4" / 108mm circumference) and 25% G1 (4 1/8" / 105mm). For European and North American buyers, we recommend a 55% G2 (4 1/4") and 45% G3 (4 3/8" / 111mm) handle mold ratio.
2. Squash Racket Throat Geometry (Open vs Closed) & 72.5–78 sq.in. Matrix
World Squash Federation (WSF) compliant rackets are engineered around a 685±2mm length, 72.5–78 sq.in. (468–503 cm²) head area, and 160g–195g frame weight across our 6 Squash OEM platforms (UN-SQ-01 to UN-SQ-06). The primary architectural decision is choosing between Closed-Throat (bridged traditional control with superior torsional stiffness) and Open-Throat (teardrop power geometry with longer central main strings), paired with 14×18, 16×17, or 16×19 string patterns at 24–28 LBS.
| Squash OEM Platform | Throat Geometry & Material | Head Size (sq.in. / cm²) | Weight & String Pattern (24–28 LBS) | Primary B2B Application |
|---|---|---|---|---|
| UN-SQ-01 / UN-SQ-02 | Closed-Throat (Bridged) Carbon-Aluminum & Full Carbon | 72.5 – 77.5 sq.in. (468 – 500 cm²) | 160–175g / 14 × 18 (UN-SQ-02) & 16 × 19 (UN-SQ-01) | Precision rail control & pro club tournament players |
| UN-SQ-03 | Open-Throat (Teardrop) Carbon-Aluminum Composite | 76 – 77.5 sq.in. (490 – 500 cm²) | 165–178g / 16 × 17 Power Fan Pattern | Explosive length drives & offensive attacking players |
| UN-SQ-04 / UN-SQ-05 | Closed-Throat Reinforced Club Durable Architecture | 76 – 78 sq.in. (490 – 503 cm²) | 175–188g / 16 × 19 High-Durability Bed | Commercial squash centers, university clubs & retail sets |
| UN-SQ-06 | High-Impact Academy Series with Reinforced Bumper | 77.5 – 78 sq.in. (500 – 503 cm²) | 185–195g / 16 × 19 Wall-Contact Resistant | Schools, public leisure centers & high-turnover rentals |
3. String Pattern Physics: 16×19 Spin vs 18×20 Control & 14×18 Squash Bed
String bed density directly governs ball launch angle, main-string snapback velocity, and string breakage intervals in both tennis and squash frames:
- Why 16×19 Dominates Tennis OEM Orders (+14% Topspin RPM): Compared to dense 18×20 grids, the 16 main × 19 cross layout widens inter-string spacing by 1.8mm in the sweet spot, allowing polyester or synthetic gut mains to deflect laterally and snap back faster—boosting topspin RPM by up to 14% at 45–60 LBS.
- When to Specify 18×20 Tennis Control Grids: Advanced flat hitters and clay-court academy buyers occasionally request 18×20 drilling to lower launch trajectory, minimize string notching, and stiffen directional response at tensions above 55 LBS.
- Squash 14×18 / 16×17 vs 16×19 Ball Cut & Durability: In squash (strung at 24–28 LBS), an open 14×18 pattern (UN-SQ-02) or 16×17 fan pattern (UN-SQ-03) bites deeper into the rubber squash ball for lethal drop-shot cut, whereas 16×19 (UN-SQ-01/04/05/06) extends string life by 35% under heavy club usage.
4. Multi-Sport OEM Customization SOP: PU Grip Sizing, Grommets & AQL 1.5 QC
At RacketOEM's Hangzhou Fuyang manufacturing facility, every custom tennis and squash batch undergoes a standardized 4-stage production and quality control workflow:
- Step 1 — Precision PU Handle Foaming & Grip Sizing (G1–G4): Two-part polyurethane (PU) is injected into CNC aluminum handle molds around the graphite shaft to form exact octagonal bevels in G1 (4 1/8"), G2 (4 1/4"), G3 (4 3/8"), or standard squash G0/G1 circumferences.
- Step 2 — PA66 Bumper Guard & Grommet Strip Injection Molding: High-impact nylon 66 (PA66) top bumper guards and double-flared grommet channels are custom-fitted to protect carbon rims from hard-court scraping and squash glass-wall collisions.
- Step 3 — Electronic Constant-Pull Factory Pre-Stringing: Frames are strung on calibrated electronic machines with synthetic gut or co-polyester strings at 45–60 LBS (52–62 LBS max rating on UN-TN-01–04) for tennis and 24–28 LBS for squash, complete with stenciled brand logos.
- Step 4 — ISO 2859-1 AQL 1.5 Head-Impact & Handle-Torque Inspection: Finished rackets pass ±3g weight/balance sorting, 60-cycle pneumatic head-drop impact verification, and handle torsional torque testing prior to retail blister card or full-cover packaging.

Frequently Asked Sourcing & Engineering Questions
What is the best-selling tennis racket head size and weight for launching a new private-label brand?
The 100 sq.in. (645 cm²) head size with a 275g–285g unstrung weight, 325mm–330mm balance, 16×19 string pattern, and G2 (4 1/4") grip—represented by our UN-TN-01 and UN-TN-03 platforms—accounts for over 70% of global B2B starter brand sales.
What is the difference between open-throat (teardrop) and closed-throat (bridged) squash rackets?
An open-throat teardrop racket (like UN-SQ-03) eliminates the throat bridge so the central main strings run longer, creating a larger trampoline sweet spot and higher ball speed. A closed-throat bridged racket (like UN-SQ-01 and UN-SQ-02) shortens the mains and reinforces the neck, reducing frame twisting for pinpoint drop shots and tight rails.
How should B2B buyers split tennis grip sizes (G1, G2, G3) for EU/US vs Asian markets?
For European and North American containers, order 55% G2 (4 1/4") and 45% G3 (4 3/8"). For Asian, Latin American, or junior/female-focused programs, order 75% G2 (4 1/4") and 25% G1 (4 1/8").
What is the minimum order quantity (MOQ) for custom-branded tennis and squash rackets?
Our OEM private-label MOQ across all tennis platforms (UN-TN-01 to UN-TN-04) and squash platforms (UN-SQ-01 to UN-SQ-06) is 100 pieces per model, including custom water decals, string color, butt-cap logo, and carry bag printing.
