Coach Shelby's racquet picker
Find a racquet that supports your game.
Tell us how you play and what you want to feel. Get three researched demo candidates with the reasons and tradeoffs behind each.
This first version focuses on standard adult racquets. Style matters alongside handling, comfort, and a repeatable swing. No email is required; answers stay in this page.
Racquet basics before you start
Head size: the area inside the hoop, usually measured in square inches. A larger area can offer more forgiveness, but does not determine the whole response.
Weight: total mass. Compare strung figures with strung figures; installed strings and accessories add weight.
Balance and swingweight: weight distribution and resistance to rotation help explain why two equally heavy racquets can handle differently. More swingweight is not automatically better.
String pattern: 16 × 19 means 16 lengthwise main strings and 19 cross strings. Pattern, spacing, strings, and technique all influence the response.
Grip and length: fit the handle to your hand and check the right length. Junior sizing needs separate attention. Don't select grip size just by gender or the professional player who endorses a model.

Know your setup
String basics, in plain English.
You don't need to know the jargon to use the picker. Start here, and choose “I don't know” whenever you're unsure.
What is the string made of?
Synthetic gut is usually a nylon string built for balanced play and value. Multifilament bundles many fibers and often offers softer feel and easier power. Polyester is generally firmer and lower powered. Natural gut is elastic and usually costs more. A hybrid combines strings in one racquet. These are categories, not guarantees about every model.
Gauge means thickness.
In the usual U.S. system, higher numbers mean thinner strings: 17 is thinner than 16. An L means a thinner version of that gauge, such as 16L. Labels vary across brands, so compare the actual diameter in millimeters.
Example: 1.20 mm is thinner than 1.30 mm. Within the same model, a thicker version generally resists breakage better. Thinner does not automatically mean better or guarantee more spin.
Check the packet, receipt, or stringer's record. You do not need to guess by looking at your racquet.
How tightly was it strung?
Tension is the pull used during stringing, usually recorded in pounds or kilograms. It is different from gauge. For example, “17 gauge at 50 pounds” describes two separate things: thickness and stringing tension.
Use your racquet's recommended range as a reference and ask your stringer how material and tension work together. Change one variable at a time.
Unbroken doesn't mean unchanged.
Strings can lose playing characteristics before they break. Record what you use, the stringing date, playing hours, and how it feels. Your own breakage rate and changing response are more useful than one replacement schedule for everyone.

I order my strings from Tennis Warehouse because I want the exact model and gauge that give me the response I rely on. That choice helps me play my game.

Your string choice doesn't have to stop at what's on your local shop's shelf. Local selection and installation prices vary. Compare the full cost, including string, shipping, and labor, and ask whether your stringer stocks or will install the setup you want.
Before ordering, confirm the exact model and thickness, the quantity needed for your racquet, and any charge for installing customer-supplied strings.
