Editorial note

R6 ADS settings need a repeatable workflow, not just a result table

This calculator is built for Rainbow Six Siege players who want cleaner scope transitions, fewer over-corrections, and a setup they can actually keep for more than one night of ranked. The numbers matter, but the workflow matters more: use one trusted baseline, map the rest of your optics around it, then verify the output with the same short drill every time.

We maintain this tool as a practical reference for Siege players after major ADS changes, optic reshuffles, and FOV-related confusion. Instead of stuffing the page with generic sensitivity advice, we focus on what you need to test, what usually breaks a setup, and where to go next if you are converting settings from another game.

Start with one trusted scope value

Pick the magnification you already use most in ranked play, then let the calculator map the rest of your setup around that baseline.

Verify in the firing range before queueing

Use a short drill of one-taps, horizontal flicks, and scope swaps to make sure the output feels stable before you commit to it.

Keep notes when Ubisoft changes settings behavior

If a season update changes optics or ADS behavior, compare your old values against a saved baseline instead of adjusting by memory.

How to use the calculator without sabotaging your own consistency

  1. Enter the ADS value you currently trust the most.
  2. Match your real aspect ratio, FOV, and multiplier so the output reflects your actual game settings.
  3. Copy the generated scope table and test it in a custom session or the firing range.
  4. Adjust only after testing the same drill twice; do not keep changing values every round.

What this tool is based on

The calculator follows the Shadow Legacy-era ADS model and is intended to help you keep monitor-distance feel more consistent between optics. It should be treated as a starting point you validate in game, not as a promise that one formula can replace testing.

Frequently asked questions

Which ADS value should I use as the starting point?
Use the scope where your aim already feels the most repeatable. For most players that is their 1.0x or 1.5x optic, because those sights cover the widest set of engagements.
Why does the calculator ask for aspect ratio and FOV?
Those settings change how the game presents movement on screen. If they are wrong, your output can look mathematically clean but still feel off when you test it in Siege.
Should I keep changing settings until the table looks perfect?
No. Use the calculated values as a baseline, run a repeatable drill, and only change one variable at a time. Most inconsistency comes from over-adjusting between matches, not from being one point away in a table.
What makes this site different from a generic sensitivity page?
This site is built around Rainbow Six Siege workflows: optic-by-optic ADS tuning, cross-checking scope transitions, and linking those outputs to broader setup guides instead of stopping at one result table.

Who this site is for

We built this site for players who care about repeatable settings, not for traffic pages written only to rank for a phrase. If you are testing a new FOV, rebuilding a setup after a patch, or bringing your sensitivity over from another shooter, the goal is to give you a cleaner process and better reference material, not to push you toward constant tweaking.
