KDP and Bookvault also take custom sizes within a range, and IngramSpark takes custom paperback sizes; the checker handles those. A size can be offered but not on every paper: the checker tells you for your paper and page count.
Where each platform prints and sells
Amazon KDP
- Sold on Amazon.com, Amazon.ca, Amazon.co.uk, Amazon.de, Amazon.fr, Amazon.es, Amazon.it, Amazon.nl, Amazon.pl, Amazon.se, Amazon.ie, Amazon.com.be, Amazon.co.jp, Amazon.com.au.
- Paperbacks can also reach bookshops and libraries through Expanded Distribution. KDP print books aren't sold on Amazon.com.br, .in or .com.mx.
- Hardcovers aren't sold on Amazon.co.jp and can't use Expanded Distribution.
- KDP's own pages disagree on whether standard colour is offered on Amazon.co.jp; check before you rely on Japan.
IngramSpark
- Printed in United States, United Kingdom, Australia. Ingram's own plants are in the US, UK and Australia. Partner printers ("Global Connect") in Spain, Italy, Germany, Turkey, India, China, South Korea, Japan, Singapore, Brazil and South Africa print for bookshops in their own country, and a plant in Sharjah (UAE) prints paperbacks for the Middle East.
- Bookshops, libraries and online stores through Ingram's network, Amazon and Barnes & Noble among them.
- Groundwood paper is printed only in the US and UK. Copies printed in Australia or by partner printers use 50# creme instead, which is a slightly different thickness.
- The partner printers in Germany and Japan don't print dust jackets.
- The partner printer in Italy prints hardcovers only at 6 × 9 and 6.14 × 9.21 in.
- Custom-size hardcovers are printed in the US only.
- The partner printers in Italy and Turkey don't print custom sizes.
- Landscape books aren't printed by the partner printers in Italy, Germany, India, Japan or Singapore.
- The Sharjah plant prints paperbacks only, so hardcovers for the Middle East come from elsewhere.
Barnes & Noble Press
- Sold on BN.com, the Barnes & Noble app.
- US only, and not in Barnes & Noble bookshops. Author copies ship within the US only.
Lulu
- Printed in United States, Canada, United Kingdom, France, India, Australia. Lulu picks the printer nearest the reader; you can't choose.
- Amazon and Ingram's network, when the format is eligible for retail distribution.
- Amazon doesn't list Lulu's printed-cover (casewrap) hardcovers; other stores get them through Ingram.
- Lulu's dust-jacket hardcovers can be sold in stores only at 5.5 × 8.5, 6 × 9 and 6.14 × 9.21 in.
- Amazon doesn't list Lulu books printed in premium colour.
Bookvault
- Printed in United Kingdom, United States, Canada, Australia. Bookvault prints in the UK itself and through partners in the US, Canada and Australia. An order a partner can't make is printed in the UK.
- Amazon (UK, US, Canada and most of Europe), the Great British Bookshop and retailers supplied by Gardners.
- Hardcovers aren't printed in Australia yet.
- 170gsm paper isn't printed in Australia.
- The Canadian printer uses only 70gsm cream and 80gsm bond, so this paper is printed elsewhere.
- Landscape books are printed in the UK only.
