I usually just eyeball the simpler stuff. I very rarely draw perspective grids on paper anymore. If it's a more complicated perspective I might do a digital perspective grid and then print it out in blue lines.
Here's a nice little Photoshop tool by Freddie Williams II that I use sometimes (I think you can still download it for free from his website)--> www.youtube.com/watch?v=8YLk96…
It's by far the fastest way for me to make a perspective grid.
Hope that helps,
