I am designing a scratch build and am going to be using a riser card for the GPU, but the case I am designing is extremely unforgiving of errors in measurements.
A watercooling fitting will be directly above the PCI-e slot so I need to know how much room for error I have.

The board is the Gigabyte GA-B150N WiFi, if that makes any notable difference?

According to the spec sheet for a Molex PCIe connector, the rise from the mounting surface to the top of the socket is 11.25mm (max.).

Feel free to look up other makes/variations to compare, but it should be standard.

Even better: buy the board you plan on using, and measure the socket height with a caliper. ;)
