PCB Hole size to use with ISP Pogo Adapter

Designing a PCB and need to know what hole size to use with the Sparkfun ISP Pogo Adapter:

It appears that it works with the std 2x3 ICSP pin header footprint, is this correct?

Yes, it’s for the 0.1" pitch 2x3 ICSP header footprint, just like the one on an Arduino.

Pogo pins don’t strictly need holes, although a hand-soldered pogo jig like this is easier to get lined up if you have them. Just stick with your usual via size; anywhere between 0.6-1.0mm works well (just testing with my pogo adapter and a template I have with various hole sizes drilled in it).

PS: Sorry to necro the thread; I hadn’t checked the date!
