90 vs 110 FOV: coverage and target size
110° adds 20° of horizontal coverage compared with 90°, while the same central target appears about 30% smaller in height at the same image dimensions.
An extra 20° of coverage with a central target about 30% smaller in height.
The jump from 90° to 110° changes both what enters the frame and how large the center looks. The wider camera reaches 10° farther to each side of forward, which can reveal additional targets and boxes. The camera position and the range stay fixed. That makes this a comparison of framing, rather than a demonstration of moving closer to a target or increasing the screen resolution.

How they differ
At 16:9, the vertical angles round to 59° and 78°. Across a plane 20 m (66 ft) forward, visible width grows from 40 m (131 ft) to about 57 m (187 ft). This increase follows the tangent of the half angle, so it is not the same as the 22% increase obtained by dividing the two degree settings. For a central target at fixed depth, the image height at 110° is about 70% of its height at 90°. That means roughly 30% smaller in height, not 70% smaller. The same scale relationship applies to an unclipped object at a fixed camera direction and image size. Newly visible objects near the wider frame’s edges can have a stretched appearance because the rectilinear projection maps oblique directions onto a flat image.
Verdict
Use 90° as the reference if you value the larger central image, and inspect 110° if the extra side coverage is the change you want. Keep the aspect ratio, game mode, and displayed image size fixed when comparing. Then test the candidate in the actual game. The geometric difference is repeatable, but it does not tell you which setting improves your play.
Understand 90° FOVWhich should you pick?
Choose 90° FOV
Choose the 90° example when you want to keep the central target larger without moving the camera. It is also a clear baseline for understanding the change because its edges sit 45° from forward. If 90° is already your current horizontal setting, hold it in View A while changing View B gradually instead of trying to judge two moving references at once.
Choose 110° FOV
Choose the 110° example when you want to inspect another 10° of coverage on each side. Watch what appears near the edges, then check whether the smaller central image remains useful at your normal screen size. Treat this as a candidate camera setting. A game with a vertical menu value or a different aspect ratio rule needs a conversion before the numbers match this preview.
