I think it depends on how wide your saddle is compared to your horse. I have one which I believe is 3/4" that I use with a single layer Mayatex blanket all the time. But now that you mention it, I have never actually measured it, so maybe I should to that. (I got it second hand from a friend). My friend is using 1" right now alone, and I DO think that 1" is too thick to use with a blanket.
I am 90% sure I am using a 3/4" right now with a blanket. The blankets come in different thicknesses too. Take a single layer Mayatex blanket for example. They come in 4 and 5 lb varieties. The 5 lbs are thicker than the 4 lb blankets. And then I have seen some really, really, thin navajo blankets as well. So thin they don't offer much padding value. So you can take that into consideration too.
The way I look at it, most western saddle pads are at least an inch thick anyway. So if I am using a 3/4" pad with a 1/2" thick blanket (and I doubt any of them are as thick as 1/2 inch), then I have a 1 1/4" thick padding system all together. My saddles tend to have generous shoulder room though. If your saddle barely has room for your horse's shoulders then probably want to go thinner.
