120 cm Planter: Best Choice in 2026
Looking for a 120 cm planter that adds height and a strong visual presence to your garden, patio or balcony? A planter of this height is available in different widths, shapes and materials, making it easy to select a version that suits the available space. From wide square models to slim or tapered designs, a 120 cm outdoor planter offers different possibilities for planting, spatial layout and a striking green accent.
What is a 120 cm planter?
A 120 cm planter is a tall planter with a height of approximately 120 centimetres. Width and depth can vary considerably, so a 120 cm planter can be available as a wide square model or as a narrower, taller version. This size is used for flowers, green plants, shrubs and other planting where height plays an important role in the layout of a garden, patio or balcony.

Material and quality
A 120 cm planter is available in different materials, each with its own characteristics. Polyester is lightweight, strong and resistant to moisture, frost and UV radiation, making it suitable for long-term outdoor use. Class A Corten steel is known for its strength and weather resistance and develops a protective layer during the natural weathering process that slows further corrosion. Depending on the version, planters can have an integrated base, drainage holes or additional water management options.
Sizes and variants
Planters with a height of 120 cm are available in many different shapes, widths, depths and configurations. In addition to wide square models, there are compact, slim and tapered versions, allowing the planter to be matched to the available space and intended use. Material, colour, base configuration and drainage options also vary between models. The available sizes are therefore not limited to a few fixed combinations: always review the full range to find the version that best suits your garden, patio or balcony.

Common mistakes
- Only considering the 120 cm height without checking width and depth
- Not considering the final weight once the planter is completely filled
- Choosing a model without first determining how excess water will drain
- Comparing different materials without considering their specific characteristics
- Assuming every 120 cm planter has the same shape or capacity
- Placing a planter on a surface that is not sufficiently stable or load-bearing
- Not considering the eventual size and root space required by the selected planting
Installation and maintenance
- Place the planter on a flat and stable surface capable of supporting the final weight
- Check the full width, depth and height of the selected model in advance
- Provide sufficient drainage according to the options available on the specific version
- Clean polyester models with water and a mild cleaning product
- For a Corten steel model with a base, use a drainage layer of approximately 10 cm of gravel with water-permeable root-resistant fabric
- Fill the planter with an airy substrate without unnecessarily compacting the soil
