プリンター用紙 vs コピー用紙：テンプレート印刷にどれを使う？
重さと仕上がりで選ぶ。方眼紙・罫線紙・Letter用紙に合う用紙。
When you're printing graph paper, lined paper, or other templates at home, the paper you choose matters. Printer paper and copy paper are the two most common options—and while the terms are often used interchangeably, there are practical differences that affect how your templates look and feel.
What is copy paper?
Copy paper is lightweight paper (typically 20 lb or 75–80 gsm) designed for high-volume copying and printing. It's economical and works well for everyday documents, drafts, and notes. Most copy paper is sized for US Letter (8.5×11 in) or A4, making it ideal for printable templates. If you're printing lined paper or grid paper for quick notes, copy paper is usually sufficient.
What is printer paper?
Printer paper is a broader category that includes copy paper but also heavier weights (24 lb, 28 lb, 32 lb) and specialty finishes. Heavier printer paper reduces show-through when using markers or highlighters—useful for graph paper or notebook paper you'll write on both sides. For templates that will go in a binder or planner, 24 lb printer paper often feels more durable than standard copy paper.
When to use each
| Use case | Recommended | Why |
|---|---|---|
| Classroom handouts, drafts | Copy paper | Cheap, fast, adequate quality |
| Notes, graph paper, lined paper | Copy paper or 24 lb | Balance of cost and feel |
| Planners, bullet journals | 24–28 lb printer paper | Less bleed, sturdier |
| Letter paper for correspondence | 24+ lb printer paper | More formal feel |
Letter paper and size
In the US, letter paper typically refers to 8.5×11 inch sheets (ANSI Letter). Both copy paper and printer paper come in this size. If your templates are designed for Letter, use Letter-sized copy paper or printer paper to avoid scaling. For international use, A4 is the standard—choose A4 paper to match A4 templates.
Summary
- Copy paper is lightweight, economical, and fine for most printable templates.
- Printer paper includes heavier options for better durability and less show-through.
- Match your paper size (Letter or A4) to your template to avoid scaling issues.
- For graph paper, lined paper, and notebook paper used with pens and highlighters, 24 lb printer paper often gives better results than the lightest copy paper.
