How to Choose the Right Sketchbook Paper Weight (GSM Guide)

Understanding Paper Weights (GSM)

Grams per Square Meter (GSM) determines paper thickness and resistance to buckling under moisture.

• 90 - 120 GSM: Ideal for daily quick graphite sketches, gel pens, and charcoal.
• 160 - 200 GSM: Heavyweight paper great for ink washes, colored pencils, and light acrylic washes.
• 300 GSM: Cold press watercolor paper designed to hold water without warping.
