Setting up new layers with exact measurements/placement

[Tomatoes]

I am making an image that will be 30" wide and 17.5" tall, but within that rectangle I'll have another set of dimensions that I need to be a blacked out layer (when I print it this center part will be removed). I'm nervous to move this around manually because if I'm off by a little bit it will make a big impact on printing.

Is there a way to insert a new layer with exact sizes and placement?
Thank you!

Hello,
I am not sure what exactly are you afraid of, coordinates on the picture that you see in Window -> Info are not enough ?

Peter, perhaps you are assuming that Tomatoes are aware of info coordinates. Most tomatoes I know, don't have a clue :mrgreen: -- sorry, sick humor.

But seriously, would you be able to guide him through how to use them? I am sure this would be valuable help. Thanks.

Wow, I've never thought about it, they usually do not share their problems when I eat them :redface:

Seriously, I will wait for Tomatoes' reaction whether this might help him and describe it in detail based on what exactly he wants, when I come back home in the evening ( European timezone ). Is that OK ?

Thank you,
Peter

Photoshop problems aside, I have found a place on the web I enjoy! :lol:

It's a correct assumption, that unfortunately I know very little about info coordinates. I'm going to poke around from there right now, but more information would be very helpful!

Essentially what I'm needing to create is a rectangle that is 30" by 17.5", my new layer will be blacked out starting from 2.25" from the top, 4.5" on from the right side, 2.5" from the bottom, and 5" from the left side. I appreciate all of your posts and help, I'll begin looking at coordinates now to see if I can make sense of it.

Sorry, correction: the overall size is 30" by 17.75...I know it doesn't change what I'm trying to figure out -- but thought I should add that I was incorrect in that measurement.

....And to pile on to all of my morning replies -- that's exactly what I needed! Sorry, I know that's elementary--but I did not know about this option. I have taught myself some rough image editing, but nothing "formal" so there are so many functions I do not know about. Thank you so much!

Hello,
thank you for clarifying, I just need two more things to know before I start to make some formulas. BTW seeing your data I do appreciate we have metric units here :lol:. I need to know size of your Photoshop document, in another words how many points does represent those 30" by 17.75 and whether you've found where these coordinates are and how they show X,Y coordinates.
Do not worry what is elementary and what is not. I bet you will explain something to me one day, something elementary for you and I will not be able to get it, that's variety in life and that is why discuss forums are so helpful
Best regards,
Peter

Using the dimensions you gave, the inside opening will be 20.5 X 13. Use the rectangle marque tool and set that as a fixed size, on a new layer. Fill it with a color, I used white against a black background in my example.

With the rectangle layer selected hit Ctr+t for transform. At the top of the tool bar options, set the reference point to the left center point and enter 5 inches in the X coordinate box. Now set the reference point (left red circle) to the top center point and enter 2.25 inches in the Y coordinate box.

So now I am totally confused. If this is the task why not measure on a real paper, why bother with Photoshop ? I have thought you have something, some picture, pattern you want to print and have the correct "window" in it already prepared. Was I wrong ?
