Calculator collection · 5 distinct tools
Screen, Image & Video Calculators
Plan pixel density, physical screen dimensions, aspect ratios, video bitrate and file size before resizing, converting or compressing media.
Screen and media tools keep pixels, physical size, bitrate, duration and decimal/binary file units explicit, then link into MAXScanner resize, conversion and compression workflows.
Open a real interactive tool instead of landing on a thin keyword page.
Formulas, units and assumptions stay visible beside the result.
Move between genuinely different calculations inside one collection.
Supplier, manufacturer, drawing and standards data remain authoritative where required.
Choose the calculation that matches the job
Each page owns a distinct input/output task. Reciprocal forms stay together when the underlying job is the same.

PPI Calculator — Pixel Density, Pixel Pitch & Megapixels
Calculate display PPI from pixel resolution and physical diagonal, with diagonal pixels, pixel pitch, aspect ratio, megapixels and common density context shown together.
Open calculatorCalculator
Screen Size Calculator — Width, Height & Area from Diagonal
Convert a display diagonal and aspect ratio into physical width, height, area and perimeter, with presets for common 16:9, 16:10, 21:9, 4:3 and 3:2 screens.
Open calculatorCalculator
Aspect Ratio Calculator — Simplify, Resize & Letterbox
Simplify pixel dimensions to an aspect ratio, calculate a proportional missing dimension and measure letterbox/pillarbox padding when fitting media inside a target frame.
Open calculatorCalculator
Video Bitrate Calculator — Target File Size, Duration & Audio
Calculate the average video bitrate required to hit a target file size after reserving an editable audio bitrate, with total bitrate and overhead margin kept visible.
Open calculatorCalculator
Video File Size Calculator — Bitrate × Duration
Estimate video file size from video bitrate, audio bitrate and duration, with MB/MiB/GB/GiB outputs and a reverse target-size link for compression planning.
