You pick up a notebook, flip through 140 crisp pages, then pause - will this fit in your work bag?
A standard 140-page A5 notebook1 measures 5.8×8.3 inches (148×210mm) with 80gsm paper2. Thickness ranges from 0.47-0.63 inches (12-16mm) depending on cover material and binding type.
Let's break down what makes notebook dimensions vary. As a manufacturer with 18 years' experience, I'll explain how paper choice, binding methods, and functional designs impact actual size.
3 key factors determining notebook thickness
- Paper density: 80gsm vs. 120gsm sheets create 1.5x thickness difference
- Binding style: Sewn bindings add 2mm vs. spiral coils adding 5mm
- Cover rigidity: Hardcovers require 3mm padding vs. softcover's 1mm
| Component | Thickness Contribution |
|---|---|
| 140 sheets 80gsm | 12mm |
| Glue binding | +2mm |
| Hardcover | +4mm |
| Total | 18mm |
What is the weight of a 200 page notebook?
Weight matters when carrying notebooks daily. Let's calculate it properly.
A 200-page A5 notebook with 80gsm paper weighs 10.6oz (300g). Hardcovers add 3.5-7oz (100-200g), while metal binders contribute 1.4oz (40g) extra.
Paper weight vs. total notebook weight
Our production data shows:
| Paper Type | Sheets | Weight (oz) |
|---|---|---|
| 70gsm recycled | 200 | 9.2 |
| 80gsm acid-free | 200 | 10.6 |
| 100gsm sketch | 200 | 14.1 |
Testing method: ISO 536 scale measurement, 10 samples averaged
