What Is Core Thickness in a Pickleball Paddle? 13mm vs 14mm vs 16mm Explained
Core thickness is one of the two specs that most affects how a paddle plays (the other is face material). Yet most paddle marketing skips past it because the explanation requires actual physics. Here it is — without fluff.
What "core" means in a pickleball paddle
The paddle has three layers: the face material on each side (typically carbon fibre or fibreglass), and the core sandwiched between them. The core is almost always a honeycomb structure — hundreds of small hexagonal cells made from polypropylene plastic, Nomex (an aramid fibre), or aluminium. Thickness is measured in millimetres from face to face.
Common thicknesses in 2026:
- 13mm — older Gen 2 paddles (Onix Z5 era). Now rare in modern paddles.
- 14mm — modern "thin" paddles. JOOLA Perseus 14mm, Selkirk Vanguard Power Air, Six Zero Quartz.
- 16mm — modern "control" paddles. The most common thickness in the category. Vatic Pro Prism, CRBN 1X, Selkirk SLK Halo.
- 19mm+ — niche thick-core paddles. Maximum control, slowest pace.
The four things core thickness changes
1. Pop (how much energy returns to the ball)
Thinner = more pop. Less foam between the ball and the rigid face means less energy absorbed by the core. The ball comes off the paddle with more speed.
If you're a power player wanting to drive third shots and put-aways with maximum velocity, thinner cores (14mm) deliver. The trade-off: less margin for off-centre hits.
2. Dwell time (how long the ball stays on the face)
Thicker = more dwell time. The ball compresses into the foam slightly longer, giving you more time to apply spin, direction, or finesse. This is why touch players (dinkers, drop-shotters) prefer 16mm cores.
Concrete impact: at the kitchen, dinking, you have an extra millisecond or two with a 16mm core to redirect the ball. Doesn't sound like much; over a long rally, it's the difference between staying neutral and going on attack.
3. Sweet spot size
Thicker = bigger, more forgiving sweet spot. The thicker foam distributes off-centre energy across a wider area before the rigid face gets involved. Translation: hits towards the edge of the paddle still come off cleanly.
For 3.0–4.0 players still developing consistent contact, the bigger sweet spot of a 16mm paddle is genuinely worth the slight pop loss. Pros find the sweet spot every time and prefer the thinner-core advantages.
4. Control on drives
Thicker = more control. Thinner cores mean the ball flies further off any error. Thicker cores absorb errors. This is the same principle as tennis racquet stiffness or golf club mass distribution: more forgiving = harder to hit awful shots, but also harder to hit the absolute best shots.
Decision matrix
| If your game / level is... | Recommend | Why |
|---|---|---|
| Brand new beginner | 16mm | Bigger sweet spot = faster improvement |
| Recreational 3.0–3.5 | 16mm | Forgiveness still matters |
| Intermediate 3.5–4.0 control player | 16mm | Touch + sweet spot |
| Intermediate 3.5–4.0 power player | 14mm or 16mm | 14mm if you can find the sweet spot consistently |
| Advanced 4.0+ tournament player | 14mm | Max pop, max spin, you find the sweet spot every time |
| Tennis convert wanting power | 14mm | Closer to the racquet feel |
| Player with tennis elbow / arm pain | 16mm | More foam = less vibration |
| Senior player (60+) | 16mm | Bigger sweet spot + softer feel |
How thickness interacts with face material
Core thickness doesn't act alone. The face material amplifies or counteracts the core's behaviour:
- 14mm core + raw carbon fibre face: maximum power AND spin (Selkirk Vanguard Power Air, Bread & Butter Loco)
- 14mm core + textured surface (CFS, grit): maximum spin even on drives (JOOLA Perseus 14mm)
- 16mm core + raw carbon fibre face: control with adequate power (CRBN 1X, Six Zero Sapphire)
- 16mm core + fibreglass face: maximum control + soft touch (Selkirk SLK Halo Control, Gamma Compass)
So when comparing two paddles' specs, look at both core thickness and face material — they tell you the paddle's design intent.
Common misconceptions
"Thicker = more powerful"
Wrong. Thicker = MORE control, LESS power. The intuition that "thicker = beefier" doesn't hold for paddle cores. Energy absorption is the operative principle.
"All 16mm paddles play the same"
Wrong. A 16mm paddle with a thermoformed shell (CRBN 1X, Six Zero Sapphire) plays harder/more pop than a 16mm paddle without thermoforming. The shell stiffness matters as much as core thickness.
"14mm is for pros only"
Mostly wrong. Recreational 3.5+ players who lean power-style and find the sweet spot consistently can absolutely play with 14mm. The "pros only" framing is mostly marketing.
"Gen 4 foam-core paddles are just thicker honeycomb"
Wrong. Gen 4 foam cores (Bread & Butter Loco, CRBN TruFoam Genesis, Honolulu J2NF) replace the honeycomb structure entirely with foam. Different physics. The thickness numbers don't compare directly between Gen 3 honeycomb and Gen 4 foam.
What about Gen 4 foam cores?
Gen 4 paddles (released 2024 onwards) ditch the honeycomb for solid foam construction. Same thickness range (mostly 14–16mm equivalents) but different feel: longer dwell time, larger effective sweet spot, more spin generation. Trade-off: cost and current banning issues. Several Gen 4 paddles have been delisted by USA Pickleball in 2024–2026 for surface roughness deviations. Always check the live banned paddle tracker before buying.

FAQ
Can I tell the core thickness by feel?
Sort of. With a few hours of play across multiple paddles, you'll feel the difference between 14mm and 16mm. Beginners can't usually distinguish them initially.
Does core thickness affect paddle weight?
Yes, but minimally. A 14mm vs 16mm paddle of the same dimensions differs by ~0.1–0.2 oz — usually less than the production weight tolerance.
Why do brands make thinner cores when thicker is more forgiving?
Tour and tournament players want maximum spin and pop, and they prioritise that over forgiveness. Thinner cores are the modern competitive choice. Marketing then trickles down to recreational players.
Should I play 13mm if I can find one?
13mm Gen 2 paddles (e.g. classic Onix Z5) are a different beast — they're typically using older Nomex cores, which sound louder and have shorter dwell time. Mostly worth it as a budget pick or for nostalgia, not for performance.
