I take a sheet that is not to scale, but I want information technology to scale

You can learn to scale an architectural plan to any scale you want

Many times, we receive plans from customers that are reduced to a page size, or are to a calibration that they can't use. For example, they take a printout of a plan that is on a small sheet, say size eight.5×eleven inches. Well, they want that same page enlarged to the full calibration that information technology was originally. In this example we are enlarging a canvass that we don't know the scale, to 1 inch = 4 feet, otherwise known as 1/4 scale. This sample works simply as long every bit the proportions are in tact. If the image has been stretched in whatever direction, this method will non work and you will have to edit information technology in image editing software like Adobe Photoshop to get all dimensions to scale. Since I am in the U.Due south., I will be showing you this procedure using imperial measurements.

Here are the things that you will demand.

  1. An architectural calibration
  2. A regular inches ruler
  3. Scratch paper
  4. A calculator
Supplies needed to scale your plans
Supplies you lot volition need to enlarge and reduce your plans to scale.

We need the sheet that y'all are printing from to exist printed out. Be certain that when y'all impress it, to select " Actual Size " and not "Fit." This will ensure the sheet you lot are measuring does not change when you print information technology.

The formula we use for this is simple.

Desire ÷ IS x 100 = percentage

Desire = size you want that dimension to measure out

IS = the size that dimension currently measures to

PERCENTAGE = the percentage  to overstate or reduce the image

Detect a large dimension on the sail that is a full number in anxiety. Endeavour to avoid a dimension like 12'nine". In my case, I have found a dimension that shows xl-feet.

Finding the IS

Take a measurement of that dimension using your ruler and write it down. In my case, that 40-feet measures to 3 ⅞ inches. It helps if you convert the fraction to decimal. Using your computer, separate vii past 8 and you come upward with 0.875. So the length is 3.875 inches .

Finding the Desire

Take your architectural scale and observe the one/4 side and measure up to the 40 notch. This is how long nosotros want that dimension to be. At present measure that to come across how long that is in inches. Use your ruler, and hold it upwardly to your calibration, like you can run across in the photograph. In my example, it measures to exactly 10-inches .

Now we only have to practise the math

10 inches (Want) divided by 3.875 (IS) multiplied by 100 gives usa 258.06% . This formula will get you lot very close, but you will desire to print the sheet enlarged to that per centum and measure it with your architectural scale, and adjust upwards or down a percentage or 2.

"Measure
Take a measurement to see if yous need to enlarge or reduce a bit to go it exact.

I have likewise made a chart so you tin find the enlargement or reduction percentage to modify the scale of a program. Here is a scale factor chart, that might help you.
