The numbers and letters printed on a tennis racket can tell you its head size, string pattern, weight class, or generation—but the meaning depends on the brand. A “100” often refers to a 100-square-inch head, for example, while “16×19” usually describes the string pattern. Neither number is usually a unique serial number.
If you’re trying to identify a racket, compare the writing on its throat with its butt-cap label, receipts, or the manufacturer’s product listings. This guide explains what common racket model numbers mean, how to tell a model name from a serial number, and what to check before buying a used frame.
What a Tennis Racket Model Number Means
A racket’s model name and number identify the product and often hint at its design. Take a name such as “Racket 100 16×19”: the 100 may refer to the head size in square inches, and 16×19 may describe the number of main and cross strings. The full model name helps distinguish that racket from other frames in the same brand’s range.
There is no single numbering system used by every manufacturer. A number might refer to head size, a weight or balance version, or simply be part of the product name. Check the racket’s printed specifications or the manufacturer’s page before drawing conclusions from one number alone.
Common Numbers and Markings on a Racket
| Marking | What it often means | What to check |
|---|---|---|
| 98, 100, 105 | Head size in square inches, when used as a specification | Some models use these figures in the name; confirm the actual spec. |
| 16×19 or 18×20 | String pattern: main strings by cross strings | A denser pattern may feel more controlled, but string and technique matter too. |
| 285 g, 300 g, 315 g | Weight, usually listed unstrung unless stated otherwise | Compare strung with strung, and unstrung with unstrung. |
| Grip size such as 2 or 4 1/4 | Handle circumference | Brands may label grip sizes differently; look for the measurement. |
| V8, V9, 2023, or similar | A version or generation identifier | Confirm the exact release and specs; naming conventions vary. |
| Serial number or barcode | A product-specific manufacturing or retail identifier | It is not usually the racket’s model name or a complete spec sheet. |
These are common conventions, not universal rules. Even a familiar name can cover several versions with different weights, patterns, or stiffness. Two rackets marked “100” can play very differently.
Model Number, Serial Number, and Product Code: The Difference
- Model name or model number: Identifies the racket line and version, such as a particular brand’s Speed MP or Blade 98 model.
- Serial number: A unique identifier that may be printed on the frame or found on a label. Its placement and format vary.
- SKU or product code: A retailer or manufacturer code used to distinguish versions, colors, grip sizes, or markets.
If a shop asks for your “model number,” it usually wants the model name and generation—not the serial number. If you’re contacting the manufacturer about a specific frame, provide a clear photo of every marking and the serial number if available.
How to Identify an Older or Used Racket
- Photograph the throat and both sides of the frame. Model names, head size, pattern, and weight may be printed there.
- Look inside the throat and on the handle. Some rackets have small specification labels or codes under the grip or butt cap.
- Record the full wording. Include letters such as “MP,” “Lite,” or “Pro,” plus any version number. Small changes can signal a different racket.
- Compare the details with reliable listings. Check head size, pattern, weight, and paint scheme. Color alone is not enough: similar paint jobs can appear on different models, and a cosmetic paint job may not match the frame underneath.
- Ask for measurements when buying secondhand. A scale and balance board can help confirm weight and balance, especially if the racket has been customized or has a replacement grip.
For example, a player who likes an older 98-square-inch racket with an 18×20 pattern should not assume that a newer racket with the same head size will feel identical. The frame shape, stiffness, balance, and weight can all change. Check the complete spec list, then demo if possible.
Five Racket Models to Consider
If you’re using model numbers to shop for a new racket, these well-known options cover different playing styles. Specs can vary by generation, so check the exact version before purchasing.
| Model | Good fit for | Strengths | Possible drawback |
|---|---|---|---|
| Wilson Clash 100 | Players seeking a comfortable-feeling, all-court frame | Easy to maneuver and approachable for many recreational players. | Its softer feel may not suit players who prefer a crisp, firm response. |
| Wilson Blade 98 | Intermediate and advanced players who value control | Offers a more precise feel for directing the ball and changing pace. | The smaller head and more demanding response can be less forgiving on off-center hits. |
| Babolat Pure Drive 100 | Baseline players who want easy power | A lively response can help produce depth and serve pace. | Players who hit flat or prefer a muted feel may find it too lively. |
| Babolat Pure Aero 100 | Spin-focused baseliners | Designed to support heavy topspin and aggressive shots from the back of the court. | Its response may not be ideal for players who want a very neutral, low-launch frame. |
| Head Speed MP | All-court players looking for a balanced option | A versatile choice for serving, rallying, and moving forward. | It may not feel specialized enough for players seeking maximum power or maximum control. |
These are starting points, not automatic matches. Grip size, string type, tension, and the racket’s actual weight can change the feel substantially. If possible, demo two or three frames with similar strings before you decide.
Frequently Asked Questions
Is a racket’s model number the same as its serial number?
No. The model name or number identifies a product line and version. A serial number is a separate identifier that may apply to an individual frame. Retailers sometimes use “model number” loosely, so ask which one they need.
Does “100” always mean a 100-square-inch head?
No. It often indicates head size when used in a racket’s specifications or name, but brands do not follow one universal naming rule. Confirm the listed head size in square inches.
What does 16×19 mean on a tennis racket?
It usually means the racket has 16 main strings and 19 cross strings. It describes the string pattern, not the racket’s model or generation.
How do I find the year of my racket?
Look for a generation label, product code, or dated listing, then compare the frame’s full name and specifications. A paint color by itself is not a reliable way to date a racket.
Final Thoughts
A tennis racket model number can point you toward useful details, but it does not explain everything about how a frame plays. Read the complete model name, check the head size and string pattern, and confirm the generation before comparing rackets. For a used frame, inspect its markings and measurements rather than relying on its paint job or a seller’s shorthand.
