Oct 27, 2025

If you have a garden or potted plants at home, you’ve probably wondered how to choose the right one. One of the most important factors when buying a tree or shrub is its size, a key piece of information that determines its future growth and how well it will adapt to your space.

In this article, we’ll teach you how to calculate a plant’s size, why it’s important, provide practical examples, and offer actionable tips to make your garden in Mallorca look spectacular. We’ll also explain how to use this information when buying plants online and how to get direct advice via WhatsApp.

What is plant caliber and why does it matter?

The caliber of a plant refers to the diameter of the tree trunk measured at a standard height, usually 30 cm from the ground in young plants or 1 meter in older specimens.

Why is it important?

  • It determines the size and robustness of the plant: a larger caliber indicates a stronger and more developed tree.

  • It affects future growth: trees of an appropriate size adapt better to transplanting and grow healthy in gardens or pots.

  • It influences the price: larger plants are usually more expensive, but your investment is more lasting.

Choosing the correct size reduces the risk of loss after planting by 30%.

How to calculate the size of a plant step by step

Calculating the gauge is simple if you follow these steps:

1. Identify the measurement height

  • For young plants: measure 30 cm from the ground.

  • For mature trees: measure 1 meter from the ground (standard reference height).

2. Use the right tool

  • Tape measure: ideal for thin or medium logs.

  • Digital caliper or vernier caliper: recommended for large trees and professionals.

3. Measure the diameter of the trunk

  • Place the tape or gauge perpendicular to the trunk.

  • Write down the value in centimeters.

4. Calculate the gauge

  • In most nurseries, the caliber corresponds to the diameter measured in cm.

  • For example: if the trunk measures 4 cm at 30 cm in height, we say that the plant has a caliber of 4.

Practical tip: For species with irregular trunks, take several measurements and use the average.

Types of plants according to their size

The size helps you decide which type of plant is most suitable depending on the space and use:

  • Small caliber (1–3 cm): ideal for small gardens, pots or terraces. Controlled growth and easy management.

  • Medium caliber (4–6 cm): perfect for medium-sized residential gardens. Good balance between size and stability.

  • Large caliber (7 cm and up): suitable for large gardens, parks or landscaping projects. Provides immediate shade and visual presence.

Practical examples of caliber calculation in Mallorca

  1. Fig tree in a pot: trunk 2.5 cm → caliber 2.5. Perfect for a terrace or urban garden.

  2. Young olive tree in garden: 5 cm trunk → caliber 5. Slow but hardy and elegant growth.

  3. Jacaranda for villa: 8 cm trunk → caliber 8. Ideal for shade and spectacular flowering.

Tip: When buying online at Medgardens, always check the gauge indicated on the product sheet to ensure compatibility with your space.

Additional tips for choosing the perfect plant

  1. Keep in mind the available space: a larger caliber means a larger tree in the medium term.

  2. Combine caliber and height: very tall plants with a fine caliber can be unstable when transplanted.

  3. Check the trunk’s health: no cracks or mold. A good diameter is only worthwhile if the tree is healthy.

  4. Ask about planting options: at Medgardens you can choose potted or bare-root plants depending on your project.
