Back-to-School Supplies: The Ultimate Guide to Choosing Wisely

The back-to-school season is approaching, and with it, the annual marathon for school supplies. Between the endless lists and crowded aisles, it can all feel overwhelming. The goal: check off every item on the back-to-school list without picking the wrong format or breaking the bank. Yet, as we all know, some purchases can quickly turn into a disaster.

As a product expert at Joybuy, my mission is to help you see things more clearly. Let's forget the marketing hype and get practical. Here are the 3 classic mistakes to avoid when buying stationery online or in-store.

1. Ink Bleed-Through: Nothing is more frustrating than a notebook where the ink shows through to the other side of the page. Poor-quality paper makes rereading difficult and gives your notes a messy look.
2. Flimsy Binding: A school planner or notebook whose cover peels off and pages fall out after just three weeks? A classic bad investment. Durability is a key factor, yet it's too often sacrificed for the sake of design.
3. Incompatible Formats: Buying a pack of single sheets for a ring binder, or a notebook with the wrong ruling, guarantees a trip back to the store in the middle of October.

To make the right choice, you just need to master a few simple technical criteria that make all the difference.

The Criteria That Make a Difference: Our Tips for Durable and Practical Supplies

Before you check out, a quick look at these three points will save your purchases from ending up in a drawer before the first school break.

1. Paper Weight: Your Best Defence Against Smudging and Bleed-Through

Paper weight, measured in grams per square metre (gsm), indicates the paper's density. It's THE #1 criterion for optimal writing comfort and preventing ink from bleeding through.

• 70-80 gsm: The standard weight for printer paper and everyday notepads like the Rhodia notepad. It's fine for a pencil or ballpoint pen, but it falls short for fountain pens or felt-tip markers, as the ink is likely to show through.
• 90 gsm: The quality benchmark. This is the renowned 90 gsm paper found in Clairefontaine or Oxford (Optik Paper) notebooks. Its opacity is perfect and its smoothness is unparalleled: ink doesn't smudge or bleed through. It's the worry-free choice for those who juggle fountain pens, markers, and highlighters.
• 120 gsm and up: This is heavyweight territory, ideal for Bristol-style revision cards, drawing, or art projects. This cardstock-like paper handles alcohol markers, India ink, and even light watercolour washes with ease.

2. Binding and Perforation: The Key to Flawless Organisation

The way the pages are bound (and whether they're detachable) completely defines how you can use your notebook or pad.

• Stapled binding (saddle-stitched): Lightweight and budget-friendly, but also the least durable. Best reserved for thin 48 or 96-page notebooks.
• Spiral binding (wire-o): Allows for a 360-degree opening, which is ultra-practical for taking notes on your lap. Much more robust than staples.
• Perforated loose-leaf sheets: A must-have for binders. Look for the term "micro-perforated" for a clean tear, and check the hole punching (usually 4 or 9 holes) to ensure compatibility with your binder.

3. Ruling: The Right Lines for Every Subject

The ruling refers to the type of lines or grid on the page. The choice is often dictated by teachers, especially in secondary school.

• Seyès Ruling (French ruling): The quintessential "grands carreaux" ruling, standard in French schools from primary to middle school. Its lines are designed to guide the learning of cursive handwriting.
• 5x5 mm Grid Ruling: The "petits carreaux" or graph paper ruling takes over in high school and higher education. It's favoured for science and math subjects because it's perfect for drawing diagrams, tables, and graphs.
• Lined: Less common in a purely academic setting, this ruling is often found in journals or planners. It's ideal for free-form writing without the constraint of a grid.

Your Questions, Answered

What's the difference between Seyès ruling and a 5x5 grid?

Seyès ruling (French ruling) is the standard in the French school system, from primary to middle school. With its main and intermediate lines, it's designed to guide handwriting practice. The 5x5 mm grid ruling is more streamlined and versatile. It's preferred in high school and higher education, especially for science and math, where it makes it easy to create diagrams and graphs.

How do I choose the right paper weight?

It all depends on your pens! For standard use with a ballpoint pen, 80 gsm is sufficient. If you're a fan of fountain pens, markers, or highlighters, upgrade to 90 gsm, like the paper in a Clairefontaine notebook, to ensure the ink won't bleed through. For durable revision cards or for drawing, aim for 120 gsm and up.

Is an undated planner a good option?

Yes, it's the ultimate in flexibility. An undated (or perpetual) planner like the Jubiluu A5 model is perfect if your academic year doesn't follow a traditional calendar, if your schedule is unpredictable, or if you want a 100% customisable tool. The advantage: no pages go to waste, even if you don't use it for several weeks.
