Overwatch 1:1 Scoped Sens

Per-hero 1:1 values, what 1:1 actually means, and how monitor distance fits in.

What “1:1” even means

Scoping reduces your FOV, so the same mouse movement covers more screen distance. Relative Aim Sensitivity While Zoomed is a per-hero angular multiplier that compensates for the zoom, independent of DPI/cm-per-360. At the right value, you move your mouse the same distance to reach a target on screen whether you're scoped or not. That's “1:1”.

Why 1:1 near the crosshair ≠ 1:1 near the edge

Your mouse maps centimeters to degrees of rotation, a fixed number of degrees per cm, regardless of FOV. But your flat monitor maps degrees to pixels through a tangent:

screen position = distance × tan(angle)

The tangent grows faster and faster as the angle increases, so the screen edges are “stretched”: one degree of rotation near the crosshair moves the image only a few pixels, while one degree near the edge moves it many. Equal angles, unequal pixels.

Top-down view of an eye looking at a flat screen Rays leave the eye at equal 10-degree steps. Where they land on the flat screen, the spacing between landing points grows wider toward the screen edge, showing the tangent stretch. eye flat screen first 10° ≈ 81 px next 10° ≈ 86 px…
Equal 10° steps of rotation land farther and farther apart toward the edge of a flat screen. Pixels-per-degree is lowest at the crosshair and highest at the edge.

Exact 1:1 at every point on screen

The exact 1:1 value changes depending on where the target is on screen. Left = crosshair, right = screen edge.

The formulas

Let F₁ = hipfire horizontal FOV (default 103), F₂ = the hero's scoped horizontal FOV, and p = monitor-distance fraction (0…1). Angles are in degrees (converted to radians for tan/atan in the code).

Linear / FOV-ratio = 100% monitor distance

sens% = (F₂ / F₁) × 100

Tangent (“true 1:1”) = 0% monitor distance

sens% = ( tan(F₂⁄2) / tan(F₁⁄2) ) × 100

General: exact 1:1 for a target at monitor distance p

sens%(p) = ( atan( p·tan(F₂⁄2) ) / atan( p·tan(F₁⁄2) ) ) × 100

As p → 0 this reduces to the tangent method; at p = 1 it equals the linear method. The calculator and chart on this page are computed from these three lines, nothing else.

Overwatch's FOV setting is horizontal FOV. Default and most common: 103.

0% = 1:1 at the crosshair. 100% = 1:1 at the screen edge.

There is no official Blizzard source for the scope multipliers or scoped FOVs. The community reverse-engineered them by measuring cm/360 scoped vs unscoped and back-solving the FOV from the sensitivity formula. Sources (16:9):
