42 to 43mm tall: do AULA's 75% keyboards call for a wrist rest in front of them?

Put a ruler next to AULA's 75% keyboards and a pattern shows up quickly: the HERO 75 HE, the AG75 Pro and the L99 all stand somewhere between 42.1mm and 43.34mm tall at their listed dimensions. That is a substantial board to type on from a flat desk. So do you need a wrist rest with keyboards this tall? For most people, a rest like the AULA F75 Wrist Rest makes the setup noticeably more comfortable.

Quick Answer

Often, yes. Each product page gives a height: 42.51mm for the HERO 75 HE, 42.1mm for the AG75 Pro and 43.34mm for the L99. With keys that high off the desk, your hands tilt back to reach them unless something raises your palms. The AULA F75 Wrist Rest, made by AULA for its own F75 keyboard, sized for a 75% layout and priced at R39 at Evetech, lifts the heel of your palm closer to key height so your wrists bend less.

📐 Why height changes the angle

Picture your forearm lying flat on the desk and your fingers reaching up to the keys. The taller the keyboard, the steeper that climb, and the more your wrist has to bend backwards to get your fingertips onto the keycaps. Held for hours, that bent-back position is what most desk ergonomics advice tries to avoid.

A wrist rest in front of the board changes the geometry. Your palm heel sits higher, so your hand approaches the keys from a flatter angle. The goal is a roughly straight line from forearm to knuckles.

⌨️ The three boards in question

HERO 75 HE

A 75% magnetic keyboard with 84 keys and a 36-LED light box across the top, listed at 42.51mm tall. It is one of the taller boards in AULA's range. Evetech's cover on the HERO and the AG75 Pro alike is a 2 Years Local Warranty.

AG75 Pro

A 75% magnetic board with 81 keys, built from CNC-machined aluminium with a carbon fibre plate inside. Its page lists a height of 42.1mm, a hair under the HERO.

L99

A 75% mechanical board with a 3.98-inch touchscreen built in, listed at 43.34mm tall. The L99 also has two-stage adjustable feet, which raise the back of the board further when extended. That makes a palm rest even more relevant if you like a steep typing angle.

🖐️ Where the F75 Wrist Rest fits in

AULA made the F75 Wrist Rest for its F75 keyboard, a 75% board. That means it is sized for this class of layout rather than for a full-size keyboard. It is not a matched accessory for the HERO 75 HE, AG75 Pro or L99 specifically, so measure your board's front edge against the rest before expecting the two to line up.

The rest's Gradient Grey colouring shades from a deep grey at its left end into a pale grey at its right, and that right end carries the AULA logo. Evetech sells it, like the L99, with a 1 Year Local Warranty.

Using it well

• Place it right against the front edge of the keyboard.
• Let the heel of your palm, not the wrist crease, settle on it when you pause.
• Hover lightly while you type, so your wrists are not pinned in place.

🤔 When you can skip a rest

If you prefer to type with your forearms supported on the desk and your hands floating, or you keep the keyboard low with its feet retracted, a rest is less important. The same applies if your chair and desk heights already keep your wrists straight. It is a comfort tool, not a requirement.

Frequently Asked Questions

Which of these three is tallest?

The L99, at 43.34mm on its product page. The HERO 75 HE follows at 42.51mm and the AG75 Pro at 42.1mm.

Do the L99's feet change the height?

Yes. Its two-stage adjustable feet raise the back of the board beyond the listed dimension.

Is the F75 Wrist Rest made for these boards?

No. AULA made it for its F75 keyboard, so it is a 75%-sized rest rather than a matched accessory for any of these three.

Can I rest my palms on the desk instead?

You can, but with a board that tall your wrists will bend upwards to reach the keys.

Do the boards and the rest share a warranty?

Not all of them. The two magnetic boards carry two years of local cover, while the L99 and the rest carry one year.
