Heights vary widely in the listings — roughly from about 8 inches up to around 37 inches — and overall sizes range from compact tabletop pots to large outdoor planters.

Drainage varies by model: some planters include a single pre-drilled drainage hole, some have no hole, some raised beds use a water-permeable base, and a few note the option to add a drainage hole or use a plug area.

Suitability depends on the product: some planters are offered for indoor use only, others for outdoor use only, and many are explicitly rated for both indoor and outdoor use.

Assembly needs differ by product: some planters arrive ready to use with no assembly required, while others list adult assembly (with or without tools); larger raised beds may include tools and a manual for setup.

The most common shapes shown are round planters and rectangular planter boxes or raised beds.

Container capacity varies by style: at least one decorative pot lists about 2.87 gallons, while raised planter boxes in these results list capacities expressed in cubic feet (examples include about 5 cu. ft. and 10 cu. ft.).

Several planters use insulating designs — for example, double-wall construction or an inner wall that helps protect and insulate roots; some listings also recommend filling the cavity between walls for added stability.
