Standard? There's nothing standard about this pergola, Willie! 
 
This is a fine lean to pergola from Rutland County, as they all are. Simple, sophisticated, stylish, salty, saucy, sassy, sumptuous, sandy. All the S's. This pergola looks great and has that class wood smell (just me?)
 
Get this pergola in about 30 days as demand is very high. Assembley can be done in a few hours so you'll be under your pergola before you know it. For more useful information have a look at the Rutland County site, then come back here and buy, please. I've a mortgage and 3 kids
