Free Creator Tools
Calculate aspect ratios, proportional dimensions, and estimated video file sizes for practical content production planning.
Creator tools ready to use
These creator utilities help plan dimensions and transfer size before an export. They calculate from the values entered and clearly separate mathematical estimates from the behavior of a real encoder or platform.
How to use this collection
Preserve proportions
Simplify a width and height to their integer ratio and calculate a matching target dimension.
Estimate delivery size
Combine video bitrate, audio bitrate, and duration to estimate decimal megabytes or gigabytes.
Leave room for encoding variance
Variable bitrate, container overhead, metadata, and codec behavior can change the final file size.
Frequently asked questions
Does the aspect-ratio tool resize a media file?
No. It calculates proportions and target dimensions; use an image or video editor to apply them.
Why can an exported video differ from the estimate?
Real encoders may use variable bitrate and add container, audio, subtitle, or metadata overhead.
