Title: text height standards?
Post by: mhillis on March 22, 2005, 11:03:02 AM
Can someone point me in the direction of a typical list of text heights for 8.5x11, 11x17, and 24x36 paper at the different scale factors. or tell me what you use to determine the height which should be used.

We use romans at 2.5 times the drawing scale, so 1:100 - 250, 1:50 - 125 etc etc etc.

We base all of our text heights on point size, which is the same basically as the Leroy sizes. This way if the client(and some still do this) is addin stick up notes to the final polo, everything will match.
In engineering we mulyiplt the point/leroy height by the scale for the final size. EXAMPLE: 8 point text = Leroy 80 guide (L80) = 0.08" at a scale of 1"=30' would be 0.08 x 30= 2.4. A point is roughly 0.01" so L60=0.06", L80=0.08", L100=0.10"etc.

here is a scale factor chart that will help you decide what scale and font size you might need

i use 3/32" for all my text...and double or 1-1/2 times the size of 3/32" for bigger fonts

You are using LDD and ignoring the Leroy style ? Makes autolabels work much easier.

We use 2.5 mm * scale factors to add text (mtext and dtext) to drawing in MS / PS the scale factors control whether or not the drawing is in metric or imperial units. Symbols and Title follow the same ideology but are different sizes.

For us, it's always 3/32" high on the plotted sheet.

Text size on the screen is determined by multiplying the dimension scale by 3/32".

Hi,
Am a newbie to this forum.
Our text is 3/32" and for the most part in paperspace.

However we have a conversion table just in case something has to be done in model space to keep everything looking the same.  We have this in our standards manual. 


DRAWING SCALE              REFERENCE SCALE        TEXT SIZE
Full Scale                               1                         3/32”
6”=1’-0”                              2                         3/16”
3”=1’-0”                              4                         3/8”
1 1/2”=1’-0”                        8                        3/4”
1”=1’-0”                         12                         1 1/8”
3/4”=1’-0”                       16                        1 1/2”
1/2”=1’-0”                        24                        2 1/4”
3/8”=1’-0”                        32                        3”
1/4”=1’-0”                        48                        4 1/2”
3/16”=1’-0”                       64                        6”
1/8”=1’-0”                         96                         9”
3/32”=1’-0”                       128                        12”
1/16”=1’-0”                       192                        18”


This way they can be consistent with dimscale and ltscale in modelspace.  Not sure if this was helpful but my 2 cents.
Hope this formats correctly.  Sorry if it didn't.

Thanks glee, that reference scale number is also quite usefull for inserting drawings into one with a different scale.  My first Cad job was in r10 and the project requirements dictated a titleblock (ms of course) at a 1/8" scale.  We had quite a time trying to figure out how to assemble various scale details on those base sheets until we figured out all of those scale factors.

Off topic posting tip: If you enclose text with [ pre ] [ /pre ] code pairs you can get it to honor preformatting, like lined up columnar text -- 
DRAWING SCALE              REFERENCE SCALE        TEXT SIZE

3”     = 1’-0”                    4                 3/8”
1 1/2” = 1’-0”                    8                 3/4”
1”     = 1’-0”                   12                 1/8”
3/4”   = 1’-0”                   16                 1 - 1/2”

1/4”   = 1’-0”                   48                 4 - 1/2”

Bringing this topic back from the dead...

In the drawing board days when working in metric, the available stencil sizes/text heights were 1.8mm, 2.5mm, 3.5mm, 5.0mm, 7.0mm and 10.0mm, are these still the acceptable text heights, or have times changed?

Many thanks
T :-)

Nor in mine ..

Generally, typically, all our annotation and dimension text height is 3.5 * dimscale < for modelspace >

This means that  A1  drawings plotted as A3 size are eminently readable.

Thanks for your input guys... I thought I was going mad. I just didnt want to come down  hard on these people until I'd double checked :-)

yip. that's what we do, 1.8 is most common, with 2.5 for headings & 3.5 for detail headings and section lines & titleblock txt.
