Dwarf trees typically reach 8-10 feet tall, compared to the standard trees, which grow up to 20 feet. Under particular conditions, some can reach up to 15-20 feet. This all depends on the type of rootstock it is grafted onto.
The standard Meyer lemon tree, asides from being available in a dwarf variety, is naturally small, measuring somewhere between 6-10 feet in height. So you can easily grow one of these trees in a container even without using a dwarf rootstock.
The standard Lisbon lemon tree typically grows 15 feet high, which may be smaller if you put them in a container. However, if you put them in the right conditions, you may see them grow up to 30 feet in height with a width of 25 feet. The dwarf variety grows as tall as 8-12 feet..
