Which keycap sets fit the Aula F99?

Explained
The short answerAny MX-stem keycap set that includes 96 percent or 1800-layout coverage fits the Aula F99. The board uses standard key sizes on a compressed 96 percent layout, so the constraint is not stem or profile, it is whether the set ships the keys for the squeezed navigation and numpad cluster.

The details

  • The F99 uses standard MX cross stems, so any mainstream aftermarket set mounts physically.
  • Community keycap-fit references and retail documentation describe a standard bottom row with a 6.25u spacebar and standard modifier widths. Still worth a glance at your own bottom row before ordering, since budget boards occasionally revise layouts between production runs.
  • The layout is 96 percent, also called 1800: a full numpad and arrows pushed tight against the alphas with almost no gaps. Sets must include the 1u keys that this compression creates.
  • Stock caps are Cherry-profile PBT per Aula and Epomaker listings, so sculpted profiles like Cherry and OEM sit naturally on this board.
  • Look for sets that explicitly advertise 96 percent, 1800, or full coverage in the kit description. Large budget PBT sets from the usual keycap brands almost always qualify.

What to check before buying

Compare the set's kit photo against a photo of your own board, key by key, across the right-hand cluster. Specifically check:

  • The numpad zero: some 96 percent boards use a 1u zero instead of the full-size 2u zero. Check which one your unit has.
  • The right shift and the modifiers next to it, which are sometimes shorter than on a full-size board.
  • The 1u keys around the arrows, where compressed layouts differ most between brands.

If the set's kit list shows those exact sizes, everything else on the F99 is standard.

What owners actually do

The typical owner move is to skip premium base kits, which are often designed around TKL and 65 percent boards, and buy a large all-in-one PBT set that lists 96 percent support on the box. Those sets include the odd 1u keys the F99 needs. Owners who want a specific premium set first check whether it sells a numpad or 1800 add-on kit, because a base kit alone can leave several right-cluster keys uncovered.

If yours is the F99 Pro

The F99 Pro shares the same 96 percent layout family, and owner reports treat keycap compatibility as identical. The safe habit is the same either way: verify the numpad zero and right shift on your specific unit against the set's kit list, since Aula has shipped multiple revisions under similar names.

People also ask

Will a TKL or 65 percent keycap set fit the Aula F99?

Only partially. The alphas and most modifiers will fit, but the compressed numpad and navigation cluster will be left with mismatched or missing keys. You need a set with 96 percent coverage.

Do XDA or SA profile keycaps work on the F99?

Physically yes, since the board uses MX stems. Uniform profiles like XDA sidestep row-matching problems on the compressed cluster, which makes them a practical choice for 96 percent boards.

Are the stock Aula F99 keycaps PBT?

Listings describe them as PBT in Cherry profile, which is why many owners keep the stock set and only swap for looks rather than quality.

Does the F99 have any nonstandard stems or key sizes?

No nonstandard stems. The sizes are standard too, but the 96 percent arrangement means you need the specific 1u and shortened keys that only larger kits include, and you should verify the numpad zero width on your unit.
