Why register

Make every page fit your planner and your printer.

An account is free. It needs a username and an email address, nothing more. Then every PDF you make is set up for you.

01
Front and back line up

Every printer shifts the back of a page a little. Print our test sheet once, type in two numbers, and every PDF moves the back to match.
02
Your public holidays

Pick your country and region, from the UK to the US, Canada and Australia. Dated pages mark your holidays, underlined so they show in black and white.
03
Always your size

Pick from 37 planner and notebook sizes. Layouts open in your size, and you can switch at any time.
04
Every PDF kept

Each PDF you make is saved to your account. Download it again whenever you need a fresh page.

Without offsets

Without offsets, the back prints a little low and to the right, so its lines and hole guides miss the front.

With your offsets

With your offsets, we move the back of every page by your two numbers, so both sides meet.
