Crop to specific size (inches or centimeters)

Hello all,

I'm looking for help to crop to a specific size either in centimeters or inches. I've done a lot of searching on this and found some posts but when I try the solutions it still doesn't work for me.

I'm printing out stencils to be applied to different items and depending on the item the stencil will be applied means I'm trying to crop the image to a specific size. For example I need my crop to be 1.75" (1-3/4") x 1.5"

So here's what I have tried: 1. Open up my image that is 2000x1333 at 72 ppi. I don't need much resolution when printing so for ease of this example I have left the print size at 72 ppi as well. 2.1.75" x 1.5" is a 7:6 aspect ratio. The picture I'm using has a lot of stuff I don't need in it so to tighten up the crop I scaled the image to 300x200. 3. I then select the crop tool and leave "Fixed" as selected and then I choose aspect ratio as 7:6 and choose the area I want to crop and I save the crop. 4. I open up the cropped image and look at it's size under "Image>Print Size" and instead of showing 1.75" x 1.5" it shows 2.0 x 1.7". When I change the 2.0 to 1.75 then the 1.7 for the height drops to about 1.4 which is pretty close but why is it not coming up as 1.75" x 1.5" or is what I'm seeing here not relevant (meaning it wouldn't actually print as 2" x 1.75")? 5. I can't even get "Size" to work under the crop feature. If I leave "Fixed" selected then this is greyed out. When I uncheck "Fixed" I can manipulate the size fields but when I enter in 1.75" as the width the height automatically changes to keep the scale (I think) and likewise when I change the height to 1.5" then the width automatically changes. I can't set both to 1.75" x 1.5".

What am I doing wrong? I'm obviously missing or not understanding something. I've been using Gimp for a long time but this is the first time I've had to crop to a print size that isn't something like 8x10, etc.

Thanks.

Karen

What are you doing wrong. Just about everything. Once again, a reminder. Gimp is a raster editor that works in pixels, not inches, not centimetres, - works in pixels.

You have an image 2000x1333 @ 72 ppi Here is one: https://i.imgur.com/PwGstOR.jpg If you open Image -> Print size with inch units it will print about 28x18.5 inches. The size is still 2000x1333 pix.

You did not really scale that to 300x200 pix did you? That was a typo in hope.

If this is going to print, now is the time to set the print resolution, say 300 ppi. The image size is still 2000x1333 pix: https://i.imgur.com/Sgo7pUa.jpg

Now you can crop the image. Gimp will use your 1.75:1.5 or if you prefer 7:6 https://i.imgur.com/uBNcUZd.jpg

Look at the top of Gimp and the image size is now 1329x1139 pix Go back to Image -> Print size and the size for printing is about 4.4 x 3.8 inches: https://i.imgur.com/jIuCnRk.jpg

Now is the time for scaling. Go to image -> Scale image set the width/height to 1.75 x 1.5 inches leave the resolution at 300 ppi. https://i.imgur.com/GDuVrca.jpg and ok that.

That gives an image 525x450 pix which at 300 ppi will print 1.75 x 1.5 inches. Set the rulers to suit as: https://i.imgur.com/3gOz87S.jpg

Thank you so much for the speedy reply Rich. Yes, I know Gimp is raster and I normally work in pixels for everything. This is the first time I tried to do this with Gimp and wasn't really sure if it was even possible (maybe I needed another program). :-)

There are two things I forgot to mention that I tried. I tried doing it all in pixels but still could only get it to about 2"W x 1.7"H and the scaling to 300x200 was not a typo but I forgot to mention I also tried not scaling (more along the lines of the steps that you provided) and still only got 2" x 1.7". I was trying everything I could think of.

In reading your steps though I can see that I missed some things as well as did things in the wrong order.

Thanks again! You've been a great help!! :-D

Cheers.

Karen
