AULA F75 vs F99: Which Layout and Control Style Fits Your Desk?

Choose the F75 when its narrower 322.7 mm listed body or rotary volume/lighting dial suits your setup. Choose the F99 when you want the separate numeric keypad depicted in its manual and have room for its 390.63 mm listed width. Both manuals document media and lighting shortcuts; those shortcuts alone are not a reason to favor the F99. These are layout and control choices, not typing or ease-of-use test results.

The buying question

Should you choose the narrower F75 or the wider F99, and which documented control workflow better fits how you adjust media and backlighting?

The F75 has a 322.7 mm listed width and a documented rotary volume/lighting dial. The F99's manual depicts a separate numeric keypad within its 390.63 mm-wide body. Both manuals document function-row media and Fn lighting shortcuts, so shortcut preference alone does not distinguish them.

Quick verdict

Choose AULA F75 White & Brown if

  • You are working within a narrower desk-width limit: AULA lists the F75 at 322.7 mm wide, about 68 mm less than the F99's listed 390.63 mm.

When the recommendation changes
  • If you regularly use a separate numeric keypad, weigh that layout against the F99's wider listed body. If compact width or a rotary volume/lighting control matters more, consider the F75; both models document keyboard shortcuts.

The differences that matter

Key Layout And Desk Footprint

AULA F75 White & Brown

AULA identifies the F75 as a 75% layout and lists dimensions of 322.7 × 143.2 × 43.1 mm.[1]

AULA F99 Black & Grey & White, Graywood switch

AULA lists the standard F99 at 390.63 × 146.78 × 42.57 mm, and its manual's keyboard diagram shows a separate numeric keypad. Its listed width is about 68 mm greater than the F75's, calculated from the two published widths.[2, 4]

What this changes: Compare your available desk width and whether you want the separate numeric keypad shown on the F99. Its wider listed body is a trade-off for that layout. Conflicting key-count or layout-percentage labels are not used to rank the boards.[1, 2, 4]

The better fit depends on your priorities

Media And Backlight Control Workflow

AULA F75 White & Brown

The F75 manual describes a dial that switches between Gaming and Office modes with a 3–5 second press. In Gaming mode, a short press changes lighting effects and rotation adjusts brightness; in Office mode, a short press mutes and rotation changes volume. The manual also lists Fn shortcuts for backlight effect, color, brightness and speed.[3]

AULA F99 Black & Grey & White, Graywood switch

The standard F99 manual maps function-row keys to media commands such as previous track, play/pause, next track, mute and volume down/up. Its mode-specific shortcut tables also list Fn combinations for lighting mode, color, brightness and speed.[4]

What this changes: The F75 adds a documented rotary press-and-turn workflow for volume and lighting. Both manuals also document function-row media commands and Fn lighting shortcuts, so those shared commands do not by themselves favor the F99. Consider whether you want the dial in addition to keyboard shortcuts; no speed or ease advantage is established.[3, 4]

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

No price-based preference is made here. Compare the current matched offers against the layout and control features that matter to you.

No purchase-timing recommendation is made; the available price context is current-only, not a sufficient history window.

Limitations

  • This comparison covers manufacturer-listed dimensions and documented control workflows. It does not establish typing comfort, sound, latency, battery life, lighting quality or real-world ease of use.
  • AULA's F99 page contains conflicting layout-percentage labels. The comparison uses its listed physical dimensions and avoids relying on a layout percentage or a key-count difference.
  • No matched long-term price history or independent controlled typing test is included.

Questions shoppers ask

How does the F75 dial control volume and lighting?

The F75 manual says a 3–5 second press switches between Gaming and Office modes. In Gaming mode, a short press changes lighting effects and turning the dial changes brightness. In Office mode, a short press mutes and turning the dial changes volume.

How much wider is the F99?

AULA lists the F75 at 322.7 mm wide and the F99 at 390.63 mm wide, so the F99 is about 68 mm wider based on those listed widths.

Methodology and sources

Compared the manufacturer-listed model widths and layout information, then checked the exact standard-model manuals for documented media and backlight controls. The approximate width difference is calculated from the two listed widths. No typing, sound, lighting-quality, or battery-performance test is claimed.
