Comments on: How to use an Architect's Scale Ruler

on 2/12/2009 I am trying to use a scale rule of 1:20

|....|....|....|....|....| etc
0 50
The markings are only 25 not 50 as marked on the rule, why and what do's it mean.

on 1/7/2009 Hello! I could probably provide better assistance if you tell me your original paper size and scale factor. 1/16th divided into one inch is 1/16th. If your paper size is not truly half of your original drawing size, then your scale factor will be distorted. For instance, a 22 x 34 drawing will be 11 x 17 at half size. This is a valid paper size. On the other hand, a 24 x 36 drawing will be 12 x 18 at half size, and this is not a valid paper size.

Hope this helps. Good luck to you.

on 1/5/2009 Let’s say my scale is 1/8 and the drawing is half size.
Therefore my scale is 1/16.
When using 1/8 scale I take the measure amount and multiple it by two
This is correct.
However when I use a 1/16 scale the answer is incorrect and that is because it is not 1/16 scale. It is one inch divided into 1/16th. Why is that?
What is going on here?
