Random Table Range Calculator
Match a die to a random table size.
How the Random Table Range Calculator works
Random Table Range Calculator turns entries and die sides into rolls to cover table. It computes that as entries divided by die faces, rounded up.
Worked example: with Entries 36, Die sides 20, this tool returns rolls to cover table 2 rolls, entries 36, die sides 20. That default state is deterministic, so you can check the page against a known result before trusting your own numbers.
Private, in your browser
Random Table Range Calculator runs entirely in your browser with no upload, account, or server call. Every figure is a planning estimate, so confirm anything important against the authoritative source or a professional before you rely on it.
Frequently Asked Questions
How does the Random Table Range Calculator work?
It computes rolls to cover table as entries divided by die faces, rounded up. It also reports entries and die sides.
Does this tool use live data?
No. It runs on the numbers you type, using local arithmetic that recalculates instantly — nothing is fetched, uploaded, or stored.
What should I keep in mind?
For an even distribution, table size should be a multiple of the die faces, or some entries are unreachable.
