A racket's feel in the hand is determined by three numbers: how much it weighs, how long it is, and where its balance point sits. These are not marketing abstractions — they are measurable physical properties that determine swing speed, maneuverability, power transfer, and fatigue over a match. Professional players specify their racket weight and balance point to within fractions of a gram and millimeter; manufacturers who cannot measure and control these parameters cannot supply product that meets professional or competitive specifications.
Weight determines overall mass that must be accelerated with each stroke. A difference of 3–5g between two nominally identical rackets — well within what manual scales miss — translates to a perceptible difference in swing momentum and arm fatigue over a match.
Balance point (the point along the racket's length at which it balances horizontally) determines whether a racket is head-heavy, head-light, or evenly balanced — and by how much. Head-heavy rackets generate more power on drives and smashes; head-light rackets are more maneuverable for net play. A balance point that varies 5–10mm between rackets of the same model means some units play noticeably differently from others — a quality consistency problem that shows up in professional user complaints and returns even when visual inspection reveals nothing.
Length affects leverage, reach, and the lever arm for power generation. For approved rackets, governing bodies set maximum length limits; for product consistency, manufacturers need length controlled to a tolerance tighter than manual measurement can reliably achieve.
These three parameters interact: a racket that is simultaneously 2g heavier and 5mm more head-heavy than the specification will play substantially differently from the nominal, even though neither deviation alone might trigger a QC reject. Measuring all three simultaneously — on every racket, in seconds — is the only way to catch combined-parameter drift.
The FH-1378 is a dedicated racket measurement instrument that simultaneously determines weight, length, and balance point position in a single placement operation. The racket is placed on the test fixture; the instrument reads all three parameters and displays them — no calculation, no repositioning, no separate weighing step.
The instrument accommodates the full range of racket sports: badminton rackets (long, lightweight), tennis rackets (heavier, stiffer frames), pickleball rackets (paddle format with shorter length), and table tennis rackets (very short, light). The fixture geometry and measurement range cover the physical dimensions of all four racket types without changeover.
At 720×380×330mm and approximately 20kg, the FH-1378 is a benchtop instrument — compact enough for a production line QC station, a R&D lab bench, or a brand quality control room, without requiring a dedicated floor footprint.
Each racket sport's governing body specifies dimensional and weight limits for approved equipment:
BWF Laws of Badminton specify maximum racket dimensions (overall length ≤680mm, width ≤230mm) and no explicit weight limit — but professional-grade badminton rackets are typically specified between 75–100g with balance points controlled to ±2mm from nominal. Manufacturers supplying BWF-level product need measurement capability at or better than these tolerances.
ITF Rules of Tennis specify maximum racket length (73.66cm / 29 inches) and width (31.75cm / 12.5 inches). There is no ITF-specified weight requirement for the racket frame itself — but professional frames are typically specified to ±3g and balance point to ±5mm. The FH-1378's ±0.2g weight accuracy and ±0.05mm balance accuracy are significantly tighter than these tolerances.
USA Pickleball official rules specify combined paddle and ball weight ≤ 9.5 ounces (269g) with no separate paddle-only weight limit, and overall paddle length + width ≤ 24 inches (610mm). The FH-1378 covers pickleball paddle length and weight measurement for these specifications.
ITTF regulations specify blade thickness, size, and composition requirements but no explicit weight limit. However, blade weight and balance are controlled by manufacturers to within tight tolerances for professional performance consistency. The FH-1378's ±0.2g accuracy covers the gram-level precision needed for table tennis blade QC.
Sport | Governing Body | Length Limit | Weight Limit | Balance Spec |
|---|---|---|---|---|
Badminton | BWF | ≤680mm | Not specified (typically 75–100g controlled) | Manufacturer-specified |
Tennis | ITF | ≤736.6mm | Not specified (typically controlled ±3g) | Manufacturer-specified |
Pickleball | USA Pickleball | Length+width ≤610mm | ≤269g (paddle+ball) | Manufacturer-specified |
Table tennis | ITTF | Blade size specified | Not specified (controlled by manufacturer) | Manufacturer-specified |
Typically 660–680mm total length, 75–100g weight, balance points ranging from 275mm (head-light) to 310mm (head-heavy) from the handle butt. The FH-1378 accommodates the full badminton racket length and weight range with accuracy well inside the ±2mm balance and ±0.5g weight tolerances required for professional-grade product.
Typically 680–740mm total length (up to ITF limit), 250–340g weight (strung), balance points ranging from 300mm to 380mm from the butt. The FH-1378 covers the length and weight range of both unstrung frames and strung rackets.
Typically 380–430mm length, 195–240g weight, balance points that vary by paddle design (power-oriented vs. control-oriented). The shorter, lighter format is fully within the FH-1378's measurement range.
Typically 255–260mm blade length, 140–190g total weight (blade + rubbers), very short handle. The FH-1378's fixture accommodates the compact table tennis racket format.
Parameter | Range Covered | Accuracy |
|---|---|---|
Weight | Full range for all four racket types | ±0.2g |
Length | Full range for all four racket types | ±0.5mm |
Balance point position | Full range for all four racket types | ±0.05mm |
The defining feature of the FH-1378 is that all three parameters are measured from a single placement — the racket does not need to be repositioned or transferred to a separate scale, length gauge, or balance fixture. The instrument reads weight, length, and balance point simultaneously and displays all three results. This is not just a convenience feature; it eliminates the repositioning errors and handling variability that sequential measurement on separate instruments introduces, and it reduces measurement cycle time per racket from several minutes to seconds.
The balance point measurement — the most technically demanding of the three — achieves ±0.05mm accuracy, which is one of the most precise commercially available specifications for racket balance measurement. This level of accuracy supports professional-grade production where balance point tolerance is specified to ±1–2mm from nominal; ±0.05mm instrument accuracy means the measurement system contributes negligible uncertainty relative to the product tolerance.
Weight measurement to ±0.2g covers the gram-level precision required for professional badminton and tennis racket QC, where weight is typically controlled to ±2–3g from nominal. At ±0.2g, the instrument's contribution to measurement uncertainty is less than 10% of the typical product weight tolerance — well within the guidance that measurement system uncertainty should be less than 30% of product tolerance for reliable QC decisions.
The entire operation is: place the racket on the test fixture, read the display. No alignment procedure, no manual calculation of balance point from weight measurements, no separate tape measure for length. The fixture geometry positions the racket correctly; the instrument handles the measurement and calculation.
The FH-1378 includes a data output interface as standard, with two ordering configurations:
With display monitor: Measurement results are output to an external monitor, making readings clearly visible at a shared QC station, and enabling connection to a PC for data logging, SPC charting, or export to spreadsheet. This configuration is recommended for production line QC programs where result recording and trend analysis are part of the workflow.
Machine only: The instrument without external monitor, for customers who have existing display infrastructure or who want to integrate the FH-1378's data output into their own factory MES or QC data system.
Configuration is specified at the time of order.
At 720×380×330mm and ~20kg, the FH-1378 fits on a standard QC bench, R&D worktable, or production line testing station. No floor space, no installation, no dedicated room — plug in (AC 220V, 5A) and it is operational.

±0.2g weight accuracy — for a professional badminton racket at 85g nominal with a ±2g production tolerance, a ±0.2g instrument has a gauge R&R contribution of 10% to the tolerance band. This is well within the 30% Gauge R&R guideline for production QC use, meaning the instrument is not the limiting factor in weight control.
±0.05mm balance point accuracy — for a racket with a ±2mm balance point tolerance, the instrument contributes 2.5% to the measurement uncertainty budget. This means that every balance point reading from the FH-1378 is essentially the true balance point of that racket — the instrument adds no meaningful uncertainty. This level of accuracy allows manufacturers to use FH-1378 data for balance point distribution analysis, not just pass/fail gatekeeping.
±0.5mm length accuracy — for a badminton racket with a BWF maximum length of 680mm, ±0.5mm accuracy allows confident rejection of any racket approaching the limit without false rejects from measurement error at the boundary.
The racket is placed on the FH-1378 test fixture in the correct orientation. The fixture supports the racket along its length in a defined position — no adjustment or alignment is required beyond placing the racket in the fixture.
The instrument simultaneously measures and displays:
Racket weight (g) to ±0.2g
Racket length (mm) to ±0.5mm
Balance point position (mm from butt) to ±0.05mm
The displayed values are compared to the product specification limits. Results are recorded for QC documentation, process control charting, or R&D data collection.
The racket is removed and the next unit placed. Total measurement cycle time is determined by handling speed — the instrument measurement itself is effectively instantaneous.
For racket manufacturers, the FH-1378 is positioned at the end of the production line for 100% inspection or batch sampling. Every racket gets its weight, length, and balance point checked before leaving the factory — catching units outside specification before they reach the customer.
The simultaneous three-parameter measurement is particularly valuable here: a racket that passes weight but fails balance point (or passes both but fails length) is caught in a single measurement step rather than requiring three separate inspections.
During racket development, engineers use the FH-1378 to measure the weight and balance implications of design changes — different frame materials, different string hole patterns, different handle constructions — before committing to tooling. The ±0.05mm balance accuracy allows engineers to detect balance point shifts of a fraction of a millimeter from design changes, giving quantitative data for decisions that previously depended on subjective "feel" assessment.
Sporting goods brands that outsource manufacturing use the FH-1378 for incoming inspection — verifying that received product matches the contracted weight and balance specification before accepting delivery — and for market sampling — pulling rackets from retail stock and verifying that in-market product continues to meet the specification over time.
The instrument's simplicity (place and read, no operator training required) makes it practical for brand QC teams who are not test engineers: a non-technical QC auditor can operate the FH-1378 reliably after a brief demonstration.
Some labs measure racket weight, length, and balance point on three separate instruments — a precision scale, a length gauge, and a balance point finder. This approach requires three handling steps, three calibrations, and aggregates the measurement error of three separate instruments. A single-instrument simultaneous measurement eliminates repositioning error, reduces cycle time, and simplifies calibration management to one instrument.
For most production QC applications with ±2–5mm balance point tolerance, ±0.05mm instrument accuracy is more than sufficient — the instrument uncertainty is negligible relative to the tolerance. If your balance point tolerance is wider (±10mm+), a less accurate instrument may be acceptable. If your tolerance is tighter than ±1mm (unusual in production), discuss with the supplier.
Confirm the instrument's weight range and resolution cover your racket range. At ±0.2g resolution, the FH-1378 is appropriate for badminton (75–100g), tennis (250–350g), pickleball (195–240g), and table tennis (140–190g). For very heavy or very light products outside these ranges, discuss range with the supplier.
Confirm the fixture accommodates your specific racket geometry. Table tennis rackets (very short) and standard badminton rackets (long and narrow) represent the extremes of the racket dimension space; the FH-1378 is designed to cover all four racket types in this range.
A badminton racket OEM producing for a European brand discovered through FH-1378 sampling data that their balance point was drifting 3mm head-heavy over a two-week production run — within the ±5mm tolerance but approaching the limit. The drift was traced to a gradual change in adhesive application volume at the handle assembly station. The data from the FH-1378 identified the trend before any rackets fell outside tolerance, allowing a process correction before defective product was produced.
A tennis racket brand conducting incoming inspection on frames from a new Asian supplier used the FH-1378 to measure 30 units from the first production batch. Weight distribution was within specification, but balance point showed a bimodal distribution — two distinct populations within the batch, suggesting two different production runs or two different frame layup batches had been mixed. The supplier was asked to segregate frames by layup batch before shipment.
A pickleball paddle manufacturer used FH-1378 data as part of their product development process to quantify the balance point shift resulting from adding edge guard protection — finding that a 12g edge guard moved the balance point 8mm toward the handle, which then required compensating by adjusting the core foam density in the head section.
Badminton rackets, tennis rackets, pickleball paddles, and table tennis rackets. The fixture accommodates the length and weight range of all four types.
Yes. Weight, length, and balance point are all measured and displayed from a single racket placement — no repositioning or separate measurement steps.
±0.05mm — sufficient for professional-grade racket QC where balance point tolerances are typically ±1–5mm from nominal. The instrument uncertainty is less than 5% of the typical production tolerance.
The FH-1378 is designed to accommodate all four racket types on the same fixture. For significantly different racket formats, the placement geometry may need confirming with the Feihong technical team for specific products.
The measurement itself is effectively instantaneous — the limiting factor is the time to place the racket on the fixture and read/record the display. In practice, throughput is approximately 15–30 rackets per minute for experienced operators at a QC station.
Yes. The FH-1378 includes a data output interface as standard. Two configurations are available: with display monitor (results shown on an external monitor for easy reading at the QC station or for connection to a PC-based data logging system) or machine only (the instrument without monitor, for integration into existing display or data capture setups). Specify your preferred configuration at the time of order.
As with all precision measurement instruments, periodic calibration against traceable reference standards is required to maintain measurement accuracy. Calibration interval depends on use frequency and the measurement accuracy requirements of your QC program; annual calibration is typical for this class of instrument in production use.
