Happy Planner Horizontal by MAMBI Review (pros, cons and dimensions)

I was going through some of the planner videos I’ve filmed and realised I never posted my walkthrough of the horizontal Happy Planner!

Pros of the Horizontal Happy Planner

  • Weekends have shaded color boxes to separate the weekend from weekday
  • Large notes sidebar in the monthly views
  • Classic Happy Planner Size (7.75″ wide x 9.75″ high, the actual planner pages are 7″ wide x 9.25″ high) – portable (MAMBI also have a full page size planner and a mini size Happy Planner)
  • The line spacing in the weekly spread is just right!
  • Laminating on the cover is durable
  • The discbound system. I’m a huge fan of discbound planning systems (I use the Arc Planner)
  • You can purchase larger disc sizes if you need more space or want to add additional pages to the planner
  • The discs come in nice colors – including gold!
  • The colors are very nice – love their use of the gold foil effect
  • Plenty of covers to choose from
  • Nice patterns on the dividers
  • Tabs are laminated
  • Each month gets a color that is used throughout the entire month (I’m a big fan of color-coordinated planners)
  • The dates for each date are placed above the daily writing spaces giving you a lot of room to write in each day
  • The daily planning boxes are the same size making it easy to plan your week with stickers etc.
  • The discbound system means you can add my own pages and pull out pages you don’t want or won’t use
  • Each planner comes in different colors and styles so a different cover means different inside page designs
  • The price is very affordable ($30USD)

Cons of the Horizontal Happy Planner

  • The monthly view starts on a Sunday but the weekly view starts on a Monday
  • If the 30th/31st of the month falls on a Sunday or Monday, rather then starting again on the top line, the last boxes of the month are split into 2 triangles so effectively you can’t write anything in those boxes and it’s dead space
  • The public holidays/events on the monthly view are at the top beside the date rather than the bottom right hand corner giving more room to write
  • No notes space in between the months
  • The calendar for each month on the left is printed onto cardstock and on the right it’s printed onto paper – maybe consider this depending on what pens you like to use in your planner
  • The tabs have color printed on the front but not on the back
  • If you want to add extra pages, you’ll need to purchase the happy planner punch – but it’s so worth to give yourself that extra customisation to make your planner your own and it’s cheaper than the Arc discbound punch
  • You can’t choose the start month – they sell 18 month pre-dated planners so sometimes you may end up paying for a couple of months you won’t use. However, you can cover the dates with date dot stickers.

The MAMBI horizontal is very similar to the Erin Condren Horizontal & The Plum Paper Horizontal except each day’s box is open ended (the other 2 planners split each day into 2 sections)

See how I used the planner for week 40 of the 52 Planners in 52 Weeks Challenge.

Pen Testing

The Happy Planner has one of the thickest (best) papers I’ve come across. There is really only ghosting (and a little bit of bleed through) for the marker pens.

Some bleed through for the Sharpie Fine Point but otherwise the paper holds up well!
