Sizes vary from shorter, wide planters to taller pots. Examples in this selection show heights of about 7"–21" and top diameters/widths of roughly 13"–20.75".
Container/growing volumes in this selection range from about 2.87 gallons up to 5.5 gallons.
Drainage options include: no drainage hole, a single or pre-drilled drainage hole, marked locations where you can drill an optional hole, and self-watering designs with a bottom reservoir and water-level monitor.
Common stability features include double-wall planters with an outer cavity you can fill (for added weight) and self-leveling feet that help keep planters steady on flat surfaces.
Many planters arrive ready to use with no assembly required. A subset—typically outdoor-style models—may note “Adult Assembly Required” and include some tools or hardware for setup.
Wipe non-porous surfaces with a damp cloth to clean. Remove liners for easier cleaning when possible, and place a saucer under planters with drainage holes to protect floors.
