2027 A5 Core Planner Horizontal
The A5 Core planner with a horizontal weekly layout pairs a structured weekly view with a full blank page for notes, lists, journaling, project planning, or anything that needs room to unfold. It is designed for people who want a calm, lightweight planner with white 52gsm Tomoe River Paper and flexible space built into every week.
This layout is especially useful if you like seeing your week at a glance, but do not want every detail squeezed into dated boxes.
The horizontal weekly layout places the dated week on the left page and leaves the right page open. It is a good fit if your plans often turn into notes, lists, ideas, sketches, tracking, or project details.

This is my 1st year with Wonderland222. My wife has used the planner for 4 years, and I have admired how organized it helps her to be. I decided I wanted to experience that for myself. I am super excited for this journey. The prey ordering process was smooth, shipping was quick and the product is amazing. I am looking forward to see what is to come.
Love it! The horizontal layout suits my needs perfectly. I'm very happy with the paper - no bleed through and normal amount of ghosting for TRP. Excited to have this as my second brain for 2027!
2nd year with wonderland! Love them
Last year I used All In One Stacked (vertical weekly) A5. Which I’ve loved dearly and used almost daily but always at least weekly. She’s chonky. Due to not having many timed appointments plus the appeal of the open format on the right page of each weekly; this year I’m going with A5 Core Horizontal. I’m super excited about 2027 I love these planners so much. Huge fan. They are perfection.
It looked exactly like the image on the website and I love it
Gorgeous planner. Delivery to EU was quick and without any issues
Just as beautiful as I had hoped!
My first full-year planner! I tried the 2026 planner starting in July of last year, and I was honestly not sure I'd keep up with it. But the 2027 one has been great, and works beautifully with my favorite fountain pens. I've set up every month with birthdays and recurring events, and I'm excited to use it next year!
My second year with Wonderland222 A5 Core horizontal. I love everything about it. Please make a passport size too.
Great product, look s as described. I am very happy with it!
I get the planner.
The color of my planner is beautiful and I can't wait to spend some time with it soon!
This is my favorite planner and I have tried all kinds!! This year's colors have hit the mark.
I abandoned the Hobonichi for this planner! The paper is excellent. The horizontal weekly layout, with one page of planner and a facing page for notes is a great design. I love all the extra space for notes as well as monthly calendars that ride with you, so the latest month is close to the month you're in instead of sitting somewhere far away in the front of the planner. Big fan!
I’m so excited to set up my 2027!! It’s so pretty!!
