Down sizeing a pattern

[edward]

When a pattern calls for a 2 3/4 clock, and you want to down size to 1 3/8 , what percentage would you use, does anyone know off hand, just curious.  edward

I'm showing my math so someone can correct me if I'm wrong.

 

2 3/4 = 2 6/8 and that is double 1 3/8, so the answer is 50%

Re: your second fraction.  3 divided by 8 = .375.  Plus the one means you want to resize to 1.375

 

Your pattern is 2.75 inches.

 

1.375 divided by 2.75 = 50%, your desired ratio.  To double check it your answer is correct take the desired size of 1.375 and multiply it by 2.  The result is 2 3/4 (2,75), your current pattern size.

 

Hope this helps friend.

I would just open it in "paint' and resize and resize until I get what I need.  I do this all the time.  I do it 10% at a time to start.

I do this the headache free and math free way for me. I load the image into Photoshop and re-size it to the dimension that I want, then print it. I'm very experienced with Photoshop, so that is my first choice for this. It can be done with many other software packages too, especially with those having layer capability..

 

For Photoshop I would just create a circle of the right size on a new layer, position and center it it over the clock circle in the base layer, and then transform the base image under the circle until the cut-out for the clock matched the circle in the layer above it, then hide the circle layer (for possible re-use) and print the base image. No math or experimentation required (and no headache).

 

My old HP Laserjet 1100 laser printer was kept as a pattern printer for making scroll saw and carving patterns because it has proven to do better than my newer inkjet printers. Cartridges are getting cheaper for it too, down to about $8 each with free shipping the last time that I ordered some.
