The Guide

Sizing & How It Works

Don’t blame me if it doesn’t fit. Here’s how to measure.

Sizes

One Mission

Choose your fit

Pocket

5 x 8 in / 12.7 x 20.3 cm

Mass market paperbacks

Penguin Classics

Most fiction hardcovers

Not sure which size?

01Remove the existing dust jacket (if any) from your hardcover book.
02Measure the height of the book cover (top to bottom of the board, not the pages).
03Measure the width of the front cover (spine edge to open edge).
04Match to the closest size. Our jackets have built-in tolerance of about ¼" for a snug fit.

Anatomy

Each jacket is a single printed sheet that wraps around your hardcover, with flaps that tuck inside the covers.

In Practice

Four steps to literary mischief.

Paper Stock

Premium weight

100lb gloss stock for standard editions, 130lb heavyweight for Premium Classics. Thick enough to feel real. Because it is real.

Finish

Satin & matte

Standard editions get a satin finish. Premium editions get a matte laminate coating that looks and feels like a real publisher jacket.

Shipping

Flat & protected

Every jacket ships flat in a rigid mailer. No folding, no creasing, no drama. Well, no shipping drama anyway.

The End

Now that you know your size, go find the perfect parody for your shelf (or someone else’s).
