14 mm or 16 mm: what core thickness actually changes

The single number that changes how a paddle plays more than any other, and why thicker is not simply better.

Cross-section diagram comparing a 14 mm and a 16 mm paddle core

If you compare two paddles and only have time to check one number, check the core thickness. It changes how a paddle plays more than the face material, more than the shape, and far more than the graphics.

The short version
  • 16 mm deforms more, holds the ball a fraction longer, and forgives a mis-hit. You supply the pace.
  • 14 mm is firmer and more direct. The ball leaves sooner and faster, whether or not you meant it to.
  • Thickness is not a skill level. Pick it from what your game needs help with, not from how long you have played.
  • Two paddles at the same thickness can still feel different, because the core material and the build method differ.

What the number actually measures

The core is the honeycomb or foam layer sandwiched between the two faces. Its thickness is measured in millimetres, and almost every paddle sold today is either 14 mm or 16 mm. A few sit at 13 mm or 20 mm, but those are outliers.

A thicker core deforms more on impact and takes longer to return the ball. That extra time is called dwell — the ball staying on the face a fraction longer. Dwell is what lets you shape a shot instead of just returning it.

Cross-section of a 14 mm and a 16 mm paddle core Two paddle cross-sections side by side. Both show a thin face skin above and below a honeycomb core. The 14 mm core is visibly shallower than the 16 mm core. Below, two bars compare relative contact time, with the 16 mm bar longer.14 mm coreFirmer.

The same paddle, two cores. Both stacks are a thin face skin above and below the core. The cut runs along the honeycomb cells, which is why they read as straight walls rather than hexagons. The difference between 14 and 16 mm is only two millimetres — about the thickness of two stacked coins — and it is enough to change how the paddle behaves.

16 mm: control, touch, and a bigger margin for error

A 16 mm core is the softer, more forgiving option. It absorbs pace rather than returning it, which is exactly what you want when you are resetting a hard drive into the kitchen or dropping a third shot short.

It also tends to feel more stable on off-centre hits, because there is more material between your hand and the mistake. If you are still finding the middle of the paddle inconsistently, 16 mm will flatter you.

The trade is pace. A 16 mm paddle asks you to generate power with your swing rather than borrowing it from the paddle.

14 mm: pace, directness, and less help

A 14 mm core is firmer. Less deformation means less dwell, and the ball leaves faster and flatter. Put-aways are easier and drives carry more.

The cost is control and forgiveness. Shots come off quickly whether or not you meant them to, and a mis-hit is punished rather than absorbed. A 14 mm paddle rewards a player who already strikes the ball cleanly and wants more of what they are already doing.

Choose 16 mm if
  • You lose points by putting balls into the net or long
  • Your game is built on resets, dinks and third-shot drops
  • You are still finding the middle of the face inconsistently
  • You want the paddle to absorb pace rather than add it
Choose 14 mm if
  • Your opponents have time to reach everything you hit
  • You already strike the ball cleanly and want more of it
  • You play a driving, front-foot game from the baseline
  • You would rather borrow pace than generate all of it

Thickness is not a skill level

It is tempting to read 16 mm as the beginner option and 14 mm as the advanced one. That is not quite right. Plenty of advanced players use 16 mm because their game is built on soft resets and patient dinking, and plenty of hard hitters at every level prefer 14 mm.

The better question is not how long you have played. It is what your game needs help with.

If you lose points by putting balls into the net or long, you want dwell — go 16 mm. If you lose points because your opponent has time to reach everything you hit, you want pace — go 14 mm.

What thickness does not tell you

Two 16 mm paddles can feel very different. Thickness sets the broad behaviour; three other things decide the rest.

Also on the spec sheet What it changes
Core material A foam-filled perimeter behaves differently from plain polypropylene honeycomb at the same thickness — usually a steadier feel toward the edges.
Build method A thermoformed unibody is stiffer than a cold-pressed build, which reads as more pop from the same core.
Face material Decides grip on the ball and therefore spin. It does not change dwell — that is the core's job.
How to check

Every paddle on this store states its core thickness, face material and core type on the product page. Where a manufacturer does not publish a figure, the listing says so rather than estimating it.
