Title 5 sand is supposed to be 1 to 2 mm particle size.
There are many types of construction sand depending on what you're doing. Utility sand is sort of course and would be about the same as Title 5. Title 5 is probably more expensive because it is graded (sieved) to be more uniform.
Sharp sand, river sand and builders sand are all the same thing. Just different regional names.
I like coral sand because it also supplies calcium carbonate. But, coral sand can increase the pH in acidic soils so watch out for that.
