Custom sizes
We offer custom size booklet printing for designs that don’t fit standard formats, such as square booklets or uniquely sized brochures and catalogues.
All custom size booklets are produced from industry-standard A-size paper, which is then trimmed down to your required finished size. When placing your order, simply choose a standard paper size that your final booklet dimensions will fit within.
Your artwork must be set up at the exact finished size you want to receive. Once you’ve placed your order and uploaded your artwork, contact our customer services team and quote your order number so we can apply the custom trimming.
If your required booklet size cannot be accommodated within the standard paper sizes available on our website, please get in touch. We’ll be happy to provide a bespoke quote and advise on production.
