The size of the hopper that comes with your garden seeder solely depends on the size of your garden. Usually, a 200 pounds hopper is enough for 5000 square feet of land. Now you can do the math. If you have a smaller garden, a garden seeder with a hopper capacity of 30 to 50 pounds will work perfectly fine for you. However, if you have a larger garden, make sure you invest in a larger capacity hopper to ensure convenience.
