What Weight Paper Is Used for Books? Complete Guide 2026

Quick Summary

Most books use 50-80 lb paper (75-120 gsm), with novels typically using 50-60 lb uncoated paper and children’s books requiring thicker 80-100 lb stock. Paper weight affects readability, durability, cost, and spine thickness – heavier paper increases printing costs by 20-30% and shipping expenses. For most books, 60 lb uncoated paper hits the sweet spot, but always consider your genre, readers, and book’s purpose when choosing paper weight.

Ever picked up a book and thought: “Man, these pages feel perfect”?

Or maybe you’ve flipped through a paperback that felt like tissue paper. (Not great.)

Here’s the deal:

What weight paper is used for books depends on a bunch of factors. But most books use paper between 50-80 lb text weight (75-120 gsm).

In this guide, as a professional book printing manufacturer, I’ll break down everything you need to know about book paper weight. Including the exact weights for different book types, how to choose the right paper for YOUR book, and some pro tips I’ve picked up along the way.

Let’s dive in.

What Is Paper Weight (And Why Should You Care)?

Paper weight sounds complicated. But it’s actually pretty simple.

Paper weight measures how thick and heavy paper is. In the US, we measure it in pounds (lb). The rest of the world uses grams per square meter (gsm).

Here’s what those numbers actually mean:

• US System: The weight of 500 sheets of paper in its basic size
• Metric System (GSM): The weight of one square meter of paper

(I know. The US system is weird. That’s why I’ll include both measurements throughout this guide.)

But here’s why this matters:

The paper weight you choose affects:

• How your book feels in readers’ hands
• Print quality and ink show-through
• Overall durability
• Your printing costs
• The book’s spine thickness

Bottom line? Pick the wrong paper weight and your book feels cheap. Pick the right one? Your book feels professional.

Standard Book Paper Weights by Genre

Let me break down the most common paper weights for different book types:

Novels and Fiction (Paperback)

Standard weight: 50-60 lb text (75-90 gsm)

Most paperback novels use lighter paper. Why? Because novels are text-heavy with high page counts. Lighter paper keeps the book from becoming a brick.

I’ve found that 55 lb cream paper hits the sweet spot for fiction. It’s thick enough to prevent show-through but light enough to keep the book comfortable.

Trade Paperbacks and Non-Fiction

Standard weight: 60-70 lb text (90-105 gsm)

Trade paperbacks need slightly heavier paper. These books often include charts, diagrams, or occasional images. The extra weight prevents bleed-through.

Pro tip: If your non-fiction book has lots of highlighted boxes or sidebars, bump up to 70 lb paper. Trust me on this one.

Children’s Books

Standard weight: 80-100 lb text (120-150 gsm)

Kids are rough on books. (Shocking, right?)

That’s why children’s books use thicker paper. Plus, the heavier weight makes colors pop for all those illustrations.

Board books for toddlers? Those bad boys can go up to 200+ lb cover stock.

Photography and Art Books

Standard weight: 80-100 lb coated text (120-150 gsm)

Art books need premium paper. Period.

The heavier, coated paper showcases images beautifully. It also prevents ink from bleeding through those full-page photos.

Cookbooks and Manuals

Standard weight: 70-80 lb text (105-120 gsm)

Cookbooks take a beating. They deal with kitchen spills, frequent page-turning, and getting propped open.

That’s why they need durable, mid-weight paper. Many also use coated paper for easy cleanup.

The Coating Question: Coated vs Uncoated

Here’s something most people don’t realize:

Paper weight is only half the equation. The coating matters just as much.

Uncoated paper:

• Feels natural and soft
• Easy on the eyes for long reading
• Best for text-heavy books
• Absorbs ink (slightly duller print)

Coated paper:

• Smooth, polished surface
• Makes images pop with vibrant colors
• Harder to write on
• More resistant to stains and fingerprints

I recommend uncoated for novels and most non-fiction. Save coated paper for books where images are the star.

How Paper Weight Affects Your Book

Let’s talk about what happens when you pick different paper weights:

Readability

Thicker paper generally means less show-through. But there’s a catch:

Super thick paper can make the book harder to hold open. I’ve seen 100 lb paper in novels. It’s like trying to read a deck of cards.

Durability

Heavier paper = more durable. Simple as that.

But remember: most readers don’t keep novels forever. They read them once and pass them on. Save the heavy paper for reference books and keepsakes.

Cost

Here’s where it gets real:

Moving from 50 lb to 70 lb paper can increase your printing costs by 20-30%. And that’s just materials. Heavier books also cost more to ship.

Spine Width

This one surprises people:

A 300-page book on 50 lb paper might have a 0.75″ spine. The same book on 80 lb paper? You’re looking at 1.25″ or more.

That affects everything from cover design to bookshelf space.

Opacity: The Hidden Factor

Quick question: Ever read a book where you could see the text from the other side of the page?

Annoying, right?

That’s poor opacity. And it’s not always about weight.

A high-quality 60 lb paper might have better opacity than cheap 70 lb paper. The paper’s fiber content and manufacturing process matter just as much as weight.

Rule of thumb: Anything under 60 lb needs excellent opacity ratings. Otherwise, readers will struggle with show-through.

Paper Color Choices

Most people think “white paper” is just… white.

Nope.

You’ve got options:

Bright white:

• High contrast
• Great for books with images
• Can cause eye strain during long reads

Natural/Cream:

• Easier on the eyes
• Traditional book feel
• Popular for fiction

Off-white:

• Middle ground option
• Works for most book types

I personally love cream paper for fiction. It gives that classic book feel readers expect.

Choosing Paper for Self-Publishing

Self-publishing? Your paper options might be limited.

Here’s what major platforms offer:

Amazon KDP:

• White: 55 lb (good for most books)
• Cream: 55 lb (perfect for novels)
• Color: 70 lb or 80 lb premium

IngramSpark:

• White: 50 lb, 60 lb, or 70 lb
• Cream: 50 lb or 60 lb
• Color: 70 lb standard or premium

My advice? Order proof copies in different paper weights. Feel them yourself before committing to a full print run.

Common Paper Weight Mistakes to Avoid

I see these mistakes all the time:

Using heavy paper for text-only books: Your 400-page novel doesn’t need 80 lb paper. It’ll feel like a textbook.

Skimping on children’s books: Kids books NEED thicker paper. Don’t cheap out here.

Ignoring opacity: Weight doesn’t always equal opacity. Check both specs.

Forgetting about genre expectations: Romance readers expect different paper than textbook users. Know your audience.

International Paper Weight Conversions

Working with international printers? Here’s a quick conversion guide:

• 50 lb text ≈ 75 gsm
• 60 lb text ≈ 90 gsm
• 70 lb text ≈ 105 gsm
• 80 lb text ≈ 120 gsm
• 100 lb text ≈ 150 gsm

(These are approximate. Actual conversions can vary slightly.)

Environmental Considerations

Here’s something cool:

Most book papers today are FSC-certified and acid-free. That means:

• Sustainable forest management
• Pages won’t yellow over time
• Better for the environment

Some printers even offer recycled options. They’re usually 10-20% more expensive but worth considering for eco-conscious projects.

The Bottom Line on Book Paper Weight

Here’s what it comes down to:

For most books, 60 lb uncoated paper works great. It’s the Swiss Army knife of book papers.

But don’t just default to “standard.” Think about:

• Your genre
• Your readers
• Your budget
• Your book’s purpose

A coffee table book needs different paper than a beach read. A manual that gets daily use needs different paper than a novel.

The good news? Once you understand these basics, choosing the right paper weight becomes second nature.

Quick Reference Guide

Need a cheat sheet? Here you go:

Novels/Fiction: 50-60 lb uncoated
Non-fiction: 60-70 lb uncoated
Children’s books: 80-100 lb coated or uncoated
Photo books: 80-100 lb coated
Manuals/Cookbooks: 70-80 lb (often coated)

Remember: What weight paper is used for books isn’t a one-size-fits-all answer. The best paper weight is the one that serves your specific book and readers.

Now get out there and make some beautiful books.
