The primary distinction between a field easel and a studio easel is in their portability and intended use:

Field Easel:

A field easel, sometimes known as a portable or travel easel, is intended for outdoor use, notably plein air painting. It is lightweight, compact, and simple to travel. Some common features of a field easel are:

Portability:

Field easels are intended to be readily transported and set up in outdoor settings. They are typically lightweight and fold into a small size for easy transport.

Stability on Uneven Surfaces:

Field easels are intended to be sturdy on uneven terrains as grass, sand, or rocky ground. They frequently include adjustable legs or spikes that may be placed into the ground for further support.

Storage and Organization:

Many field easels include built-in storage compartments or bags to keep art equipment including paints, brushes, and palettes. These storage alternatives enable painters to transport their equipment easily while working outside.

Adjustable Angle and Height:

Field easels usually have adjustable features that let artists set the canvas or painting surface at different angles and heights, accommodating their preferred working positions.

Studio Easel:

Designed for use in a studio or indoor setting, a studio easel is generally larger, sturdier, and more stationary than a field easel. Key features of a studio easel include:

Stability and Durability:

Studio easels provide stability and support for larger canvases or artworks. They are often made from sturdy materials like wood or metal to ensure durability and long-lasting use.

Adjustable Height and Angle:

Studio easels typically offer a wide range of adjustments, allowing artists to work comfortably at various heights and angles. They may have multiple points of adjustment, such as a sliding mast or a crank mechanism, to accommodate different canvas sizes and working preferences.

Storage and Organization:

While some studio easels may have small storage compartments or trays for holding brushes or other supplies, their primary focus is on providing a stable and adjustable platform for painting rather than portable storage.

Additional Features: 

Studio easels may have additional features like a built-in palette holder, brush rests, or accessory trays to provide convenience and organization during the painting process.

Summary: 

A field easel is designed for outdoor use, emphasizing portability, stability on uneven surfaces, and storage options. A studio easel, on the other hand, is intended for indoor use, prioritizing stability, adjustability, and support for larger artworks. The choice between a field easel and a studio easel depends on an artist's specific needs, working environment, and preferences.
