印刷用紙の重さ：GSM vs lb
GSMとlbの違いと、ノート・プランナー向けの目安。
printingpaperplannerstemplates
When you print templates at home on printer paper or copy paper, weight affects everything: ink bleed, show-through, and how durable the sheet feels in a binder. Most printer paper and copy paper fall in the 20–24 lb (75–90 gsm) range.
GSM vs LB: what’s the difference?
- GSM = grams per square meter (common internationally)
- LB = pounds (common in the US, but varies by paper type)
Because “lb” depends on the paper category, GSM is often the clearer spec when comparing papers.
Practical paper weight ranges
| Use case | Recommended range | Notes |
|---|---|---|
| Everyday notes | 75–90 gsm | Affordable, easy to print |
| Planner pages | 90–120 gsm | Less show-through, sturdier |
| Markers / heavy ink | 120–160 gsm | Better for bleed control |
What to choose for ruled and graph templates
- For classroom notes (college/wide ruled), 80–90 gsm is usually enough.
- For graph paper used with pens and highlighters, 90–120 gsm feels better.

Tip: printer settings matter too
If you switch from 80 gsm to 120 gsm, adjust your printer “paper type” setting (plain vs heavy). That helps ink dry correctly and reduces smearing.
