Gaming and PC Calculators

eDPI, cm/360, Field of View, PSU Wattage and PPI Calculators

Six calculators for the numbers behind a gaming PC and the settings menu: matching mouse sensitivity between games, translating field of view between the conventions different engines use, checking whether a processor and graphics card are a sensible pair, sizing the power supply and working out how sharp a monitor will look from your chair.

Build a gaming PC — Six calculators that check a gaming PC build from PSU to aim.

eDPI and sensitivity conversion

The eDPI calculator multiplies mouse DPI by in-game sensitivity, converts the result between CS2, Valorant, Apex, Overwatch 2, Call of Duty, Fortnite, Rainbow Six and other games using each engine's yaw value, places the figure against the range professionals use and gives the sensitivity to set at other DPI settings.

Centimetres per 360

The cm/360 calculator gives the physical mouse travel for a full turn in centimetres and inches, labels it high, medium or low, suggests a mouse pad width and, given a target distance, returns the sensitivity to type in, with a table across common DPI values.

Field of view

The FOV calculator converts a field of view between horizontal, vertical and diagonal for your resolution, translates the 4:3-based figure that CS2 and Valorant use into the 16:9 figure Overwatch and Call of Duty use, and shows what the same setting gives on 16:10, 21:9 and 32:9 screens.

CPU and GPU bottleneck

The PC bottleneck calculator compares relative gaming performance for a processor and graphics card at your resolution and game type, reports which part is limiting frame rate and by how much, and repeats the estimate at 1080p, 1440p, ultrawide and 4K.

Power supply wattage

The PSU calculator adds up the gaming load of a build from its processor, graphics card, memory, drives, fans and cooling, allows for overclocking and the transient spikes of modern graphics cards, and recommends a standard wattage and efficiency tier with a table of every common size.

Monitor pixel density

The monitor PPI calculator turns resolution and diagonal size into pixels per inch, dot pitch, physical dimensions, aspect ratio and the scaling setting that suits the screen, and with a viewing distance gives pixels per degree and the distance at which individual pixels disappear.
