I'm new to actual drawing with Photoshop. I'm trying to draw an Interior Elevation of a room to a specific size. For example, one wall is 18'-6" wide by 10' tall. I want to draw a rectangle to this size; how do I do that?

Use the rectangle tool and specify the exact size you want it.  Or just drag it out and watch the size in the info palette.

Photoshop does have a fixed size option for the rectangle tool, and you can type in any units you want (ie: 8 in, 8 cm, 8 mm, 8 pt, etc.)

You can add the literal "in" or "cm" to the end of your number and it will figure it out.

When someone says "I'm new to photoshop, I want to draw a rectangle...", "Use the rectangle tool" is not particularly helpful.

Yes, there is a rectangle tool. Select it.



Instead of dragging a rectangle, click once in your image and a dialog should appear giving you the option to specify the width and height of your new rectangle.

Making an image that is literally 10 feet across is really overkill. If you did do that, I would recommend first changing the image ppi (pixels per inch) to be something like 16px/inch so each pixel is equivalent to 1/16th inch. Or work out your own scale conversion...

Image -> Image Size , then change the "Resolution" setting to be 16 instead of what it is set to, which is probably 72 or higher.

Okay! I was tying a quotation mark instead of actually doing "in". That was the problem haha. Thank you everyone.
