Tools You’ll Need

• A ruler (preferably one that begins at zero on the edge)

• A triangle or right-angle tool (such as a carpenter’s square or bookend)

A flat, stable surface with a vertical backstop (such as a table against a wall or the inside corner of a sturdy box)

1. Measuring the Height (H)

• Lay the book flat on the table with one short edge (head or tail) lightly touching the backstop. Do not compress the book.

• Lay your ruler along the top of the book with the zero point at the backstop.

• Using the triangle, find the tallest point of the book by sliding it along the edge and checking the ruler where the triangle meets it.

• Take multiple measurements along the width of the book and use the tallest measurement.

2. Measuring the Width (W)

• Lay the book flat with its spine touching the backstop.

• Do not press the book against the backstop—let it rest naturally.

• Place the ruler flat on top of the book, zero end at the backstop.

• Use the triangle to touch the fore-edge (the outer edge opposite the spine) and record the measurement where the triangle meets the ruler.

• Measure at several points across the height of the book and use the widest measurement.

• Include any raised bands, clasps, or cover overhangs in your measurement.

3. Measuring the Thickness (T)

• Lay the book flat on the table.

• Stand the ruler upright vertically beside the book.

• Place the triangle against the backstop and slide it down gently until its horizontal edge just meets the thickest part of the book.

• Read the measurement where the triangle intersects the upright ruler.

Check several points and use the thickest measurement.

Additional Tips

• Don’t press or flatten the book while measuring—let it rest in its natural state.

• If your book is fragile or warped, note that in your submission. We can adjust accordingly.

• If your book has irregular features (such as warped boards, protrusions, tabs, or loose elements), please let us know.

• If you’re unsure or the book is especially valuable, feel free to send a photo with a ruler in the frame for scale.
