What gearing for 10p set?

Enjoying my single speed but decided to build another multi speed bike for more challenging trails. I am buying a 10 speed cassette and derailleur from a friend who has taken it off his cube but need the front sprocket.
I see that the most common size is 36 or 38t, is this about right to give me a good range of gear ratios across the 10? I ask as I run a 33/16 set up on the ss and thought a smaller front sprocket would be the way to go, somewhere in between the 22/36 most 20 spd bikes run, maybe a 28?

Assuming you have a 11-34 or 11-36 ten speed cassette, 36 or 38 chainrings will be fine for any 1x10 MTB. 38T chainring with a 29" bike will get you a lot more top end speed than 36T with a 26" bike, and any combination will be a ton easier for climbing than singlespeed... at worst, half the gear-inches compared to 33x16.

I still am on 26" wheels and am running my 1x10 with a 35t chainring (gotta love Renthal for the one-tooth increments ). I decided this after trying out a 38t for a while and finding it a bit high and knowing I did not want to go with the commonly-used 32 as there were too many high-speed sections I knew I would spin out on.

So far, it has proved to be a good 'tweener choice, although there are times I would love to have a 42t rear cog.

I don't have the tractor legs you have and I'm fat, so take that into account. I run my SS with a 32T front and switch the rear cog anywhere from 17 to 22. Mostly on a 20 though. I tried to go 1x10 with a 11-36 cassette. I tried 32T, then 30T and if 28T would have fit I might have been able to get it to work out for me, but ultimately decided 3x10 with a 22/30/40 crankset works for me. I have ridden my friends fatbike with 1x11 and the 28-42 granny works pretty well, but 28-10 spins up a bit too easily on long downhills or extended flat sections.
