Different borders sizes on rectangles

Similar to what JJ said, but I would Control+Alt+T to transform a copy of the path in a Shape layer. With the reference point set to top left, put the left and top border sizes in the X and Y fields. In the Width and Height fields, you can take advantage that Photoshop now allows simple math in numeric fields, so you would add  the total borders left and right, or top and bottom, to the existing values.

After the transform, in the Shape tool, set the path operations to Exclude Overlapping.

Scripting would be good for this, since you could give better UI controls than, the Transform Options bar, which I find painfully fiddly to use. You could also edit the border sizes later by independantly adjusting the size of the two rectangles.

Another idea would be to make an Action for making your 2 rectangles or writing a script.

The simple answer to your question is no, you can't do this in Photoshop, borders are the same on all sides. Your workaround is how I would do it.

MULTIDIMENSION  wrote (eg. top: 5px, left: 2px, bottom: 2px, right: 2px) and I don't know if there is an option for this.

To modify Myra's answer just a bit, enable the checkbox for relative. You will need three passes:

• Width of 4 px from center center
• Height of 2 px from top center
• Height of 5 px from bottom center

Try adjusting the Canvas Size and Anchor

Photoshop rectangle Shapes or laters with different sizes each side stroke it itself a rectangle fill or two rectangles that are different sizes stacked. Layers sizes are easy to transform to size. What is hard about free transform.  From the middle  from any achor point values in option var what not to like.
