Padel frames come in three shapes. The shape decides where the mass sits and, with it, how large the forgiving area of the face is — the part usually called the sweet spot.
Round
The widest sweet spot of the three, with the balance closest to the hand. A contact away from the middle still goes roughly where it was aimed, which is the single most useful property while a swing is still settling. It is also the easiest of the three to move quickly, because less weight is carried out towards the head.
Teardrop
The middle shape. The balance sits further forward than a round frame and further back than a diamond, and the sweet spot sits between the two in both size and position. Catalogues sometimes write this as tear.
Diamond
The balance sits highest of the three, so more weight is carried into the ball. That is where a smash finds its pace. The trade is a smaller forgiving area: a contact away from the middle loses more than it would on a round frame.
Shapes outside the three
Not every maker uses the three-way vocabulary. Some publish shapes of their own — hybrid and geometric both appear in this catalogue, because that is what the manufacturer wrote. Where that happens the value is recorded as published rather than forced into the nearest of the three, which would misstate it.
Sweet spot is not a measurement
No maker publishes the sweet spot as a number, and this catalogue does not invent one. What the shape tells you is where the mass is and therefore roughly how forgiving the face will be. How much that matters depends on how consistently a player already meets the ball in the middle — which is a fact about the player, not the racket.
Shape and swing speed
The three shapes suit different swings rather than different abilities. A diamond head rewards a swing that is already fast, because the mass it carries high only reaches the ball if the head is moving. Applied to a slower swing it gives less than a round frame would, while still being less forgiving about where the ball lands on the face.
A round frame works the other way. It is easier to accelerate, and the wider forgiving area covers a contact that is not perfectly placed. That is useful whether the swing is still developing or simply tired at the end of a long match.
Oversized and other variants
Some makers publish a shape with a qualifier — an oversized round, for instance. The qualifier usually describes a face larger than the family's norm, which extends the forgiving area further still. Where a maker publishes it this catalogue records the whole phrase rather than trimming it to the base shape, because the qualifier is the part that distinguishes the frame.
Regulation limits the extremes
Padel frames are made within a size limit set by the sport's rules, so the difference between the shapes is real but bounded. No shape is dramatically larger than another; what changes between them is where inside that outline the mass is placed.
