There are usually 4 or 6 different scales on it. Each one corresponds to a
specific scale (1/4" = 1', 1/2" = 1' etc.)
Usually each major marking is in feet and the minor ones near zero are
inches or multiples thereof.
To use the 1/4" = 1' scale place the scale on paper. Make a mark at 0. Then
make a mark at whatever distance the scale reads (say 10). You will now have
a line which is 2 1/2" long but which would represent 10 feet on the
Same thing goes for metric or engineers scale except the ratios and markings

Oh, I thought he was asking for Arachniphobic scales,
which weigh your fears about spiders. They're in OD.
I have no ideas what a "directionsor" tutorial is or
where to find one. Maybe in Cuba? No, that's directiones

You could always refer to the owner's manual but here goes:
1. Lay scale on drawing with flat side down.
2. Connect first point of item to be measured with the zero point
located on the scale.
3. Find number on scale for second point of measurement.
4. Read number.
Repeat as necessary

No kidding. The amount of effort expended in ridicule exceeds the effort
required simply to answer the question.
Architect scales are not rocket science. (Rocket scientists use engineering
scales anyway.) I assume you're talking about an architect's scale in
Each edge sports two scales, one reading left-to-right and the other reading
right-to-left. That's just so that they can fit several scales onto one
physical stick. The number in the margin at each end is the fraction of an
inch that's intended to represent one foot in the scale that begins at that
end. For most house plans, the 1/4 scale is used. That's one-fourth inch
in the drawing equaling one foot in the finished product.
On my scale the 1/4 scale shares an edge with the 1/8 scale. The 1/4
numbers start at the left and march to the right, while the 1/8 numbers
start at the right and increase to the left. Make sure you pay attention
which numbers and which tick marks refer to which scale. Since there are
tick marks every 1/8 inch for the 1/8 scale, two of those ticks represent a
foot in the 1/4 scale. So make sure you're using the right set of numbers.
Now on the "negative" side of the zero tick mark (to the left of zero on my
1/4 scale) is one scaled foot's worth of inch ticks. Or, if the scale is
too small, ticks for every two or three inches. It might be clearer if you
find one of the larger scales like 1/2 or 3/4 and look at its subdivided
So if you need to draw a line representing 14 feet 3 inches, lay out the
scale so one end point is on the "3 inches" tick in the subdivided foot, and
your other end point will be at the "14" tick. If you're reading lines
using the scale, lay the zero tick at one end point and see which "foot"
tick is closest to the other end point without being longer. Then slide the
scale so that this foot marking is on the other end point. That gives you
the "feet" portion of the measurement. The first end point will now lie
within the subidivded foot area and give you the "inches" portion of the
Oh, wow. Thank heaven for the metric system where no such
ultra-strange confusions occur! 1/4 scale every unbiased observer
would consider to be one unit in the drawing signifies 4 units in the
real worls (or maybe vice versa), but that 1/4 really means 1:48...

I was trained as an engineer, but grew up in a house full of architects. My
drawing station has a hodge-podge of architectural and engineering tools.
Anyway, in engineering we frequently use decimal subdivisions of English
units instead of the base-two fractions used by most of the American and
English readers of this group. So a quarter-inch dowel pin is shown on the
engineering drawing as having a diameter of 0.2500 inch and not 1/4 inch.
Yes, we still it a "quarter-inch dowel pin".
Most of us can work in metric units just as easily. Technical people can
usually see the advantages to metric measurements at least in terms of easy
computation among measurements and international interoperability. But the
average American sees little advantage to using metric units. There's no
clear advantage to buying milk by the liter as opposed to by the quart or
gallon. There's no clear advantage to baking in Fahrenheit degrees instead
of Celsius degrees. But there's a perceptible disadvantage in trying to
convert wholesale from one system to another, in the form of error and
miscalculation. That first generation that has to abandon its familiar
system in favor of an unfamiliar system with little or no advantage gained,
tends to stall the migration.

Possibly, except that the scale notation is usually more explicit. Although
the scale instrument used in creating the drawing lists only the fraction,
the notation in the drawing will say something like
1/4" = 1'
where the " and ' are abbreviations for inch and foot, respectively. In
practice it's very difficult to mistake 1/4 scale for 1:4 or even 1:48.

Notice the slash '/' meaning fraction, not ratio. So it should be
absolutely obvious to someone who is not a complete fool that it is
not a ratio, but means 1/4 inch to one foot (1/4"=1'), which is about
the same as 1:50 (note the colon, not slash) on your metric scale.
Considerable savings in scale manufacturing are obtained by omitting
the ["=1'] part. Equally obvious is the 3/32 scale on my scale. It
should be immediately obvious to anyone with more than half a brain
that the ratio is 1:128.
Get with the program, Juergen! It's time to abandon your antiquated
19th century metric system based on base 10. This is the 21st Century,
where everything is base 2, so 1:128 = 1:2^7 or 1:1000000. I leave the
hexadecimal equivalent as an exercise for the reader.
I'll let one of the Muricans to explain to you the
penny/shilling/pound system for measuring the length of nails and why
it is so much better than measuring them in inches or millimetres.

he stands on a basis of some half-square foot, has to straddle out
