Rainbow Six Siege locks vertical FOV at 60° — there is no in-game FOV slider. This fixed system means aspect ratio is the only way competitive players influence their field of view. On 16:9, Siege's 60° vFOV equals approximately 90° horizontal. On 21:9, this expands to roughly 110°. This calculator shows you exactly what horizontal FOV you're playing at on your setup.

| Playstyle / Setup | Recommended FOV | Type | Notes |
|---|---|---|---|
| 4:3 Monitor | ~73.7° | Horizontal (from 60° vFOV) | Very narrow — essentially unused in competitive play |
| 16:9 Monitor | ~90° | Horizontal (from 60° vFOV) | Standard competitive setup — vast majority of pro play |
| 16:10 Monitor | ~93.5° | Horizontal (from 60° vFOV) | Slightly wider — premium monitors and MacBook players |
| 21:9 Ultrawide | ~110° | Horizontal (from 60° vFOV) | Significant advantage — often restricted in ESL and Ubisoft tournaments |
Everything competitive players need to know about R6 Siege FOV settings.
Ubisoft fixed Siege's vertical FOV at 60° as a deliberate competitive balance decision. A locked FOV ensures no single player can gain a fundamental visibility advantage through settings alone — within 16:9 play. This is why aspect ratio becomes the primary competitive FOV lever, and why 21:9 is controversial.
21:9 monitors give Siege players approximately 20° more horizontal FOV than 16:9 players — from ~90° to ~110°. This is a substantial advantage in a game where pixel-perfect angles and drone positioning are central to winning rounds. Most major Siege tournaments (ESL Challenger, Ubisoft's own events) restrict play to 16:9 output.
Siege's close-quarter combat within building interiors means 90° horizontal FOV is actually well-suited to the game. Unlike open-world BR games, most engagement ranges in Siege are short. The fixed 90° FOV maintains consistent peeking angles — learning these angles is a core skill, and changing FOV (via aspect ratio) disrupts that learning.
At Siege Major and SI level, players almost universally compete on 16:9 monitors at 1920×1080. The locked FOV system means there's no FOV optimization race — pros focus on refresh rate (144–360Hz), monitor size, and in-game settings like texture quality and shadows instead.
