They are 5.25 inches wide by 5.5 inches tall. They have attached saucers and are made to fit a regular 4" or a 4" tall drainage plastic pot. These pots are made so it is almost impossible for the orchid to stand in water. The attached saucer also has side drainage. The perforation designs provide excellent air flow. These pots come in six different colors with a glossy finish. Color shades vary slightly from pot to pot. They are perfect for phalaenopsis.
