Book / zine weight estimator

Estimate total book/zine weight from trim size, pages, paper gsm and quantity.

Use tool

Approximation only; final shipping weight should be measured.

How to use it

Estimate the weight of A5, B5 or A4 booklets from body-page count, body-paper gsm and quantity. It is intended as an early shipping/event estimate such as “roughly how heavy will 100 copies be?”

  1. Choose A5, B5 or A4.
  2. Enter a whole body-page count, body-paper gsm and whole-number quantity.
  3. Review estimated weight per copy and total weight, then weigh finished books before making a final carrier decision.
Body estimate
page area × gsm × body pages ÷ 2
Cover assumption
simple 200 gsm cover allowance
Other allowance
another 5% for a rough ink/binding factor
Output
grams/copy, total kg and approximate body sheets

Use A5, 64 pages, 90 gsm and 100 copies for an early load estimate

The calculator treats 64 body pages as about 32 body sheets per copy, then adds its fixed cover assumption and simple allowance before multiplying by 100 copies.

Cover stock, inserts, lamination, special binding and ink coverage are not entered separately. If a shipment is near a carrier weight limit, weigh the finished books rather than relying on this estimate.

Body-paper gsm strongly affects the result

A 70 gsm body and a 110 gsm body can produce very different shipment weights even at the same trim size and page count. Use the paper specification from the printer when possible.

The cover is a fixed approximation

The tool assumes a simple 200 gsm cover contribution. Heavy board, specialty stock or layered finishing can make the real copy heavier.

Enter body pages rather than counting the cover again

The page input is for the book body. Page count and quantity are treated as whole counts, while gsm can remain a positive numeric value.

Box limits are a separate planning step

Total book weight does not include carton, padding or a carrier’s per-box limit. Add packaging weight and split the shipment accordingly.

Use measurement for the final decision

Before printing, an estimate is useful. After delivery, weighing a stack such as ten finished copies and calculating an average gives a more reliable packing figure.
