Free pickleball calculator suite.

Finding the right pickleball paddle isn't just about brand names or what your friends are using — it's about matching specs to the way you actually play. Grip size, weight, shape, core thickness, and even overgrip layering all affect how a paddle performs in your hand. We built this free pickleball calculator suite so you can make confident, data-backed decisions without the guesswork.

Grip size calculator

Grip size is the foundation of paddle comfort. Too large, and you lose wrist snap and control. Too small, and you'll over-grip, leading to blisters and forearm tension. Our grip size calculator uses either a direct hand measurement or a height-based estimate, then rounds to the nearest standard 1/8" increment. It also accounts for overgrip layers and includes a visual grip size chart so you can double-check your result. Works for all hand sizes — men, women, and juniors.

Paddle weight advisor

Weight determines the feel of every shot. Lighter paddles give you faster hands at the kitchen line, while heavier ones add stability and drive power from the baseline. The paddle weight advisor asks about your play style, arm sensitivity, and typical session length to recommend a target weight range between 7.2 and 8.8 oz. If you're experimenting with lead tape or weight placement, the result gives you a clear baseline to start from.

Paddle shape guide

Standard (16" × 8"), Hybrid (16.25" × 7.8"), or Elongated (16.5" × 7.5") — each shape trades off sweet spot size, reach, and maneuverability differently. The paddle shape guide scores all three against your play style and ranks your top two fits side by side. Especially useful when comparing paddles from different brands that use different naming conventions for the same shapes.

Core thickness advisor

Core thickness is one of the least understood paddle specs, but it has a major impact on how the ball feels off the face. Thinner cores (14mm) produce more pop and a crisper response; thicker cores (16–20mm) absorb more energy, giving you a softer touch and less vibration transferred to your arm. The core thickness advisor weighs your preferences for power, control, and comfort to suggest the right thickness for your game.

Overgrip weight adjustment

Every overgrip layer adds roughly 7 grams to your paddle and increases the grip circumference by about 1/16". That might sound small, but it shifts the balance point toward the handle and changes how the paddle swings. The overgrip calculator shows the exact impact of one, two, or more layers — helpful if you're fine-tuning feel or managing grip comfort in humid conditions.

Arm-friendly paddle finder

Arm pain is one of the most common complaints among regular players, and equipment choice can either help or make it worse. The arm-friendly paddle finder generates spec recommendations focused on minimizing vibration and reducing impact shock. It considers core thickness, weight, and grip size together, then builds a primary and backup setup designed to keep you playing without discomfort.

Round robin generator

Organizing fair rotations for rec play or a local tournament is harder than it looks — especially with odd numbers or limited courts. The round robin generator creates balanced schedules for any group size, whether you're running doubles with 8 players on 2 courts or a larger bracket. Every schedule ensures equal partnerships, balanced opponents, and fair bye rotations. Results are printable and ready for the courts.

How to get started

If you're new to paddle fitting, start with grip size — it's the single most impactful spec for day-to-day comfort. From there, explore paddle weight and shape to narrow down what feels right for your game. Every tool on PaddleFitHub is completely free, runs instantly in your browser, and remembers your inputs locally so you can pick up where you left off.
