Okay so I’ve been testing A4 week-to-view diaries for literally three months now because 2026 planning is already happening and honestly I’m drowning in samples on my desk right now. My cat knocked over the Moleskine one yesterday which… actually let me tell you about that one later.
The Paper Quality Thing Nobody Tells You
Right so first thing you gotta check is the paper weight because here’s what happened – I bought this gorgeous looking diary last year, looked perfect in the photos, got it and my fountain pens bled through immediately. Total disaster. For 2026 you want minimum 80gsm but honestly 100gsm is where it’s at if you’re using anything beyond a basic ballpoint.
I tested the Leuchtturm1917 A4 week-to-view and their paper is 80gsm which sounds fine but with my Pilot G2 pens (the 0.7mm ones) there was slight ghosting. Not bleeding exactly but you could see the writing from the other side. The Rhodia ones though – they use 90gsm and it’s chef’s kiss. Zero show-through even when I was testing different highlighters.
The Brands I Actually Tested With My Own Money
So I bought like eight different 2026 diaries because apparently I have no self-control when it comes to stationery. Here’s the actual breakdown:
- Leuchtturm1917 A4 Week-to-View (the navy one is stunning btw)
- Rhodia Goalbook A4
- Moleskine XL Weekly (this is the one my cat attacked)
- Quo Vadis Minister – sounds fancy, it’s French
- Blue Sky Enterprise A4
- AT-A-GLANCE Professional
- Collins Elite Manager
- Filofax A4 Refillable
Layout Differences That’ll Make or Break Your Planning
This is gonna sound weird but the actual layout matters SO much more than I thought. Some week-to-view diaries give you equal space for each day which seems logical right? But then Saturday and Sunday get the same amount of room as Wednesday and for most people that’s just wasted space.
The Quo Vadis does this thing where weekends are condensed into one column and honestly I hated it at first but then I used it for two weeks and now I get it. If you’re not working weekends you don’t need that real estate. But if you’re like me and clients book Sunday sessions sometimes… you’re gonna feel cramped.
Oh and another thing – some diaries start the week on Monday, some on Sunday. The American brands usually do Sunday starts which messes with my brain because I’m so used to Monday. Check this before you buy because it’s surprisingly annoying to adjust to.
Time Blocking Space
The AT-A-GLANCE Professional has hourly slots from 7am to 6pm which is great if you’re scheduling meetings all day. But here’s what I found – if you’re doing more task-based planning rather than appointment-based, those time slots just sit there empty looking sad. I ended up using the Collins Elite instead because it has open columns for each day. You can write tasks, appointments, whatever without being constrained by pre-printed times.

Wait I forgot to mention – the Blue Sky one has this notes section at the bottom of each week that’s actually huge. Like way bigger than the tiny strips most diaries give you. I spilled coffee on mine last week which actually tested the paper quality accidentally and it didn’t bleed through to the next page so that was a win I guess?
The Binding Situation
Nobody talks about binding enough and it drives me crazy. You’ve got three main types for A4 diaries:
- Hardcover with sewn binding (lies flat-ish)
- Spiral/wire binding (lies completely flat)
- Ring binder/refillable (flexible but bulky)
The Leuchtturm and Moleskine both have sewn binding which means they don’t lie totally flat unless you crack the spine. Some people don’t care but when I’m writing in a diary on my desk I want it FLAT. The spine-cracking thing also damages the binding over time.
Spiral binding is where it’s at for pure functionality. The Blue Sky and AT-A-GLANCE both use wire spirals and they lie perfectly flat. Downside is the spiral can get bent if you throw it in a bag, and it looks less professional if you’re pulling it out in meetings. I had a client look at my spiral diary once and make a comment about it looking like a school notebook which… okay rude but also she had a point.
The Filofax Situation
So Filofax does refillable A4 inserts which is a whole different approach. You buy the binder once (expensive) and then just buy new inserts each year. I’ve been using this system since 2024 and honestly it’s growing on me. You can add sections, remove months you don’t need anymore, customize the whole thing.
But – and this is a big but – the binder itself is heavy. Like my Filofax A4 setup weighs probably double what the Leuchtturm weighs. If you’re carrying it around daily that matters. If it lives on your desk then who cares.
The Features You Think You Want vs What You’ll Actually Use
Okay so funny story – I got the Collins Elite specifically because it had these ribbon bookmarks (three of them!) and all these extra planning pages at the back. Goal setting worksheets, project planning grids, the whole productivity pr0n package. Used the ribbons for maybe two weeks. Never touched the planning pages.
Here’s what I actually use constantly:
- The monthly overview pages before each month (essential for seeing the big picture)
- A pocket at the back for random receipts and sticky notes
- Corner perforations on pages (surprisingly useful for tearing out weeks to give to my assistant)
- A proper elastic closure band so papers don’t fall out in my bag
Things I thought I’d use but don’t:
- Those tiny address book sections (it’s 2026, everyone’s in my phone)
- International holidays listed for like 12 countries (I only need UK or US ones)
- Year planners for 2027 already (I can barely plan 2026 thanks)
- Metric conversion charts??? Who put this in here???
Size Reality Check
A4 is big. Like properly big. I feel like the photos online don’t convey how much desk space these things take up. If you’re working from a small desk or cafe tables a lot, it might be too unwieldy. I was watching that new Netflix show last night while testing diaries on my couch (yes I’m that person) and the A4 was awkward to balance on my lap.

The Rhodia Goalbook is technically A4+ which means it’s slightly taller to accommodate binding. This is actually smart design but also means it doesn’t fit in standard A4 bags and pouches. Found that out the hard way when I bought a cute diary cover that was too small.
The Week-to-View Space Math
So an A4 page is 210mm × 297mm. In a week-to-view layout, you’re usually looking at a two-page spread for one week. That means each day gets roughly 60-70mm of width depending on margins and binding.
Sounds like plenty until you’re actually writing in it. I typically have 4-6 tasks per day plus 2-3 appointments plus random notes. The Moleskine felt cramped. The Quo Vadis was perfect. The Blue Sky was almost too spacious which feels like a weird complaint but then I felt obligated to fill the space.
Price Breakdown Nobody Asked For But Here It Is
I tracked what I paid for each because my accountant is gonna ask about these receipts:
Budget tier (£10-15): Blue Sky, AT-A-GLANCE, Collins
Mid-range (£20-30): Leuchtturm1917, Moleskine
Premium (£35-50): Rhodia, Quo Vadis
Refillable system: Filofax binder £60-80 + inserts £20 yearly
The budget ones are honestly fine if you’re using basic pens and don’t care about paper quality. The Blue Sky shocked me with how decent it was for £12. The premium ones justify their cost with better paper and construction but diminishing returns after £30 in my opinion.
The Specific 2026 Date Thing
Okay so 2026 starts on a Thursday which is kind of an awkward start. Some diaries begin their week view with December 29 2025 to get a full week, others just start with January 1st even though it’s mid-week. The Leuchtturm starts with the full week which I prefer because I do yearly planning over New Year’s and need that space.
Also 2026 has no particularly weird calendar quirks. Easter is April 5th which is relatively early. Christmas is on Friday which means that last week of December is gonna be weird for work planning but good for holiday planning.
Monday vs Sunday Start (Yes This Again)
I mentioned this before but it’s actually a bigger deal than you think. If you’re buying from US brands they almost always start on Sunday. UK and European brands do Monday. Some brands like Leuchtturm offer both versions so CHECK WHICH ONE YOU’RE ORDERING.
I accidentally ordered a Sunday-start diary in 2024 and tried to make it work for three months before I gave up and bought a different one. My brain just couldn’t adjust to seeing Sunday on the left side of the spread.
What I’m Actually Using for 2026
After all this testing I’m going with the Rhodia Goalbook for my main diary. The paper quality won, basically. I use fountain pens and colored pens constantly for client work and I need zero bleed-through. The £28 price tag hurt but it’s literally the tool I’ll use every single day for a year so… justified.
My backup recommendation if you don’t wanna spend that much is the Collins Elite Manager. It’s £15 on Amazon right now, has decent paper (not amazing but good enough), lies reasonably flat, and the layout is clean. No weird quirks or gimmicks, just a solid diary.
For people who want spiral binding specifically, the AT-A-GLANCE Professional is the best one I tested. The wire binding is sturdy, pages are perforated if you need to remove them, and it’s only £18.
The Ones I’m Returning
The Moleskine is going back. It’s pretty but £32 for paper that ghosts this badly is not acceptable. Also the elastic closure is already getting loose after three weeks of testing which doesn’t bode well for a full year of use.
The Quo Vadis is gorgeous but that condensed weekend layout isn’t working for my schedule. If you work strict Monday-Friday with empty weekends, get this one. It’s beautifully made.
Random Tips from Three Months of Testing
Start your diary in December 2025 even though it’s technically for 2026. You need that transition period to build the habit and also December is when everyone’s planning January anyway.
Don’t buy matching accessories upfront. I bought a fancy pen loop and sticky note holder for my Leuchtturm and never used them. Add accessories after you’ve used the diary for a month and know what you actually need.
The color you choose matters more than you think. I bought a black Moleskine thinking it looked professional but it’s so boring to look at every day that I avoid opening it. The navy Leuchtturm though? I actually want to use it.
Test your actual pens in the diary before committing to a whole planning system. Some stores will let you write on a sample page. Do this. I cannot stress this enough.
Oh wait one more thing – if you’re buying online, order early. Like now. The good 2026 diaries are already selling out in popular colors and by December you’ll be stuck with whatever’s left. I tried to get the Rhodia in purple last week and it was already out of stock everywhere.
