10 gallon cooler will be plenty big for 90% of the recipes out there for 5 gallon batches.
Your tun needs to hold: ~1.4qts per pound of grain and figure the grain displaces .08 gallons per pound. Thats about 1.72qts per pound in displacement. A 10 gallon tun could do about a 17 pound grain bill to the tippy top.You could cut back to about 1.25 qts per pound if your grain bill gets big like that.
