How to set a specific defined brush size in Ps CS5

Thanks for any help.

The size is set by the initial graphic i.e. if you define it using a large graphic then you get a large brush, make it small you get a small brush. You should still be able to adjust the size when using it, and you could always resize it make a mark then define a new brush from that mark.

Thanks. Man, that doesn't sound very accurate to me. Anyway, Let me explain, I'm using Illustrator CS6 and Photoshop CS5 together. I'm coverting old vector shapes in illustrator that are badly segmented back into compound paths and transfering those vectors into PS to create vector masks where I can smooth and blur the mask in define mask properties then creating the brush. A long and tedious process to be sure but I can't figure any other way around it. Some vectors I'm creating into shape libraries. I've tried the size part of your suggestion in both programs and also I've made both documents 72dpi but no matter what I do even using snap to guides the brush size definition (see image)  jumps around when creating it. In other words I can't define a size of 1000 or 2500 px it just sets it on it's own when it opens up. Is it the same in the latest version of Photoshop? I know I can increase the size of the brush after it's made so that beg the question why have the size defined in the creation of the brush at all then? it seems to not make sense or am I looking at it all wrong?

Hi
The brush size is set from the trimmed borders of the area of the brush image you selected. In other words both this:

and this :

Will give the same brush size, as it is defined by trimming the non-white area and taking the longest side

Okay now we're cooking, I didn't know that. What I was doing was selecting the image and surrounding it with marching ants and then defining the brush. The result was random brush sizes. I'll give this a try right now as I'm about to get back to work and down to business again. Thanks Dave! It's the little things & details that get you LOL!
