Starrett Combination Square is the tool you need for this operation.
Calipers or a dial indicator mounted on a block also perform perfectly.

I'd use a 4" Double Square. That sucker's handy!

That's what I use. I set it to the depth I want, set it on the ruler
end and raise the bit/cutter until the top tip just nicks the head. I
then make a test cut, but it's usually within a 32nd.

The more difficult task for me is adjusting the width of cut,
especially on the shaper. This is where a tool like the Trend Depth
Gauge could really shine. Set your fences dead straight with each
other, set the gauge to the depth you want, then butt the fence back
until the outside tip of the cutter just nicks the ruler. I'd imagine
you could get it within the same 32nd right out of the gate.
Unfortunately it doesn't look like the Trend gauge has the necessary
width to handle most shaper cutters.

I wonder if anyone makes a similar gauge with "feet" that are set wider
apart and perhaps a little bit larger overall... That would be
timesaver for me for sure.
