Paper weight (lb vs gsm)
The short answerPaper thickness is measured in pounds (lb) or GSM; MCRL quotes in lb. Heavier paper feels more premium; lighter paper keeps a high-page-count book from getting bulky.
Did you know?
Heavier stock means better opacity and less bleed-through. That matters when people write in your planner.
Watch
The details
The right weight depends on your page count, the type of paper (coated or uncoated), your artwork, the binding and the look and feel you want.
| Product | Typical paper | Why |
|---|---|---|
| Illustrated hardcover (children's, art, cookbook) | 80lb to 105lb gloss or matte coated | Smooth, vibrant images; substantial feel |
| Text-heavy book | 65lb to 80lb uncoated | Less glare; lighter for high page counts |
| Journal or planner | 65lb to 100lb uncoated, white or ivory | Writable; heavier means less bleed-through |
| Card set | 10pt to 18pt gloss or matte coated | Rigid enough to handle |
| Board book | 40pt to 100pt board (1mm to 3mm) | Built for little hands |

Common questions
Why does MCRL quote in lb rather than gsm?
Lb is the measure commonly used in the United States and by offset printers. It is the weight of a standard ream (500 sheets) of that paper, so a higher number means thicker, heavier paper.
