Scale Conversion Charts

May 4, 2012

Great work - Love them, thank you.

Other scales I would like to see:

1:50 (diecast model trucks)
1:72 (model aircraft)
1:76 (OO scale)
1:87 (HO scale)

Cheers,
Greg

some people refer to this as being"half scale" or "quarter scale", could you explain that and how it would apply to your charts?
thanks

Half scale and quarter scale mean different things to different folks. Sometimes, a half scale model means something that is 50% of the original size - in a ratio of 1:2. Same deal with quarter scale, a model that is 1:4.

But some hobbyists use the term in different ways. In the dollhouse world, 1:12 is (or was) the most common scale. Half scale dollhouses are 50% smaller than 1:12 - which is 1:24. 1/2" = 1'-0" is another common ways to express 1:24 when dealing with architectural drawings. If someone asked me from across the room, "What scale is this drawing in?" I might answer "half" - meaning 1/2" = 1'-0", but that would be confusing to someone in a different industry. Same logic: Quarterscale dollhouses are 25% smaller than 1:12 - which is 1:48. Also expressed 1/4" = 1'-0"

Which is why I use the ratios for these charts - even though I use the more colloquial terms in person - because the colloquial terms are confusing across various industries and hobbies. I use "1to48scale" or "toscale" to tag items on thingiverse, because the tagging system doesn't deal well with punctuation and alternative characters in tag names.

You said you might be willing to make additional scales. How about some used for Role Playing Games (RPGs)? I would like 30 mm scale (1:60) which is the standard for d20 system games. I would think other popular choices would be 20 mm (1:91), 25 mm (1:76), and 28 mm (1:64) scales.

Tex - I will try to get these together for you in the next week or so - I'll send you a message when they are up!

A zip of all the files together would be nice.
