Sight-size or comparative measurement: which should beginners use?

Short answer: Sight-size places the drawing beside the subject so both appear the same size from a fixed viewing spot; comparative measurement judges proportions against each other at any scale. Sight-size is excellent for training accuracy, while comparative measurement is more flexible for everyday work, and most painters eventually use both.

Sight-size

You set your easel so the canvas sits next to the subject, step back to a marked spot, and compare them directly. Because they appear the same size, errors are easy to spot. It demands a controlled setup and a fixed position.

Comparative measurement

You pick a unit, for example the height of the head, and relate every other distance and angle to it. It works at any size and anywhere, from a sketchbook on a train to a large canvas.

A practical recommendation

Clint Atelier workshops teach the comparative method because it travels with you. Sight-size exercises are a strong supplement when you have the space to set them up.
