Understanding Paper Weight: GSM vs. lb
What is GSM (Grams per Square Meter)?
GSM measures the mass of one square metre of paper, not its exact thickness. A higher GSM usually means more material, but caliper, stiffness, and bulk also depend on fibre composition, coating, and compression. For bond or writing paper, common reference points are approximately 20 lb = 75 GSM, 24 lb = 90 GSM, 28 lb = 105 GSM, and 32 lb = 120 GSM. The lb equivalent must always include the paper grade because bond, text, and cover papers use different basis sizes.
U.S. Basis Weight (lb) Explained
In the U.S., paper gets a “pound” label, like 20 lb or 32 lb. This can be tricky because it changes for different paper types. GSM is easier since it’s the same everywhere. That’s why Labon Stationery and other big companies use GSM to keep things clear.
Why Paper Weight Matters for Writing and Planning
Paper weight changes how paper works with pens. It stops ink from leaking or showing through. It also makes paper feel cheap or fancy. For Labon Stationery, picking the right GSM makes sure their notebooks are perfect for writing diaries, planning days, or taking work notes. The right paper makes everything better!
Recommended Paper Weights for Different Uses
70–90 GSM: Standard Writing and Office Use
This is super common for printer paper or cheap notebooks. It’s light and cheap, but ink might leak through, especially with fountain pens or markers. It’s okay for quick notes but not the best for fancy stuff.
100–120 GSM: Everyday Journals and Planners
This is the best spot for most notebooks! 100–120 GSM feels smooth, isn’t too thick, and stops ink from showing through. Lots of Labon Stationery notebooks use this paper weight for awesome quality without being bulky. It’s great for daily planners or journals.
120–160 GSM: Premium Journals and Artistic Use
Heavier paper, like 120–160 GSM, feels super nice and fancy. It’s perfect for people who love a cool touch or use lots of ink types. This paper weight is awesome for artsy journals, bullet journals, or mixed media stuff. Labon makes these for special writing or drawing.
160+ GSM: Specialty Applications
Super thick paper, like 160+ GSM, is for sketchbooks, watercolor journals, or special inserts. For brands wanting a wow-factor gift, like a fancy work notebook, Labon Stationery offers custom thick paper. It’s tough and feels like a treat!
Factors to Consider When Choosing Paper Weight
Ink Compatibility and Bleed-Through
Pens act differently on paper. Thin GSM soaks up ink and might let it leak or show through. Labon Stationery tests their papers with all kinds of pens to make sure they work great and keep ink where it belongs.
Paper Texture and Finish
How paper feels—smooth, rough, or shiny—changes how writing goes. Labon Stationery has smooth, matte, or special textures in lots of GSM choices. You can pick what feels best for your pen!
Binding and Notebook Thickness
Thicker paper means fewer pages in a notebook. Labon Stationery helps balance paper weight with how big the notebook is and how it’s held together. This is super important for planners or journals with tons of pages.Labon’s online notebook configuration currently lists hardcover, flexi-cover, softcover, ringbound, and other formats; A6, 13 × 21 cm, A5, and A4 sizes; 128 to 528 printed pages; plain, ruled, dotted, or grid interiors; and standard paper selections of 80, 90, or 110 GSM. Heavier or specialty paper should be confirmed as a custom request because paper bulk, spine width, page count, and binding strength must be evaluated together.
Portability and Page Count
Heavy GSM makes notebooks heavier. If you want a light planner for travel, Labon Stationery can pick the right layout and paper to keep it easy to carry. You get a cool notebook without too much weight! For example, an A5 notebook with 160 printed pages contains 80 physical sheets. Its approximate inner-paper mass can be calculated as 0.148 m × 0.210 m × 80 sheets × GSM. At 100 GSM, the paper block weighs about 249 g; at 120 GSM, about 298 g; and at 160 GSM, about 398 g, excluding the cover, endpapers, adhesive, ribbon, and other accessories. Moving from 100 to 120 GSM therefore adds approximately 50 g before any cover changes are considered.
Paper Weight Selection Table for Buyers
| Intended Use | Starting GSM Range | Typical Writing Tools | Main Procurement Check |
|---|---|---|---|
| Promotional and office notebooks | 80–90 GSM | Pencil, ballpoint, standard gel pen | Portability, page count, and unit cost |
| Daily planners and journals | 100–120 GSM | Gel pen, rollerball, fine fountain pen | Ghosting, drying time, and two-sided writing |
| Premium bullet journals | 120–160 GSM | Fountain pen, brush pen, light markers | Spine bulk, binding strength, and page turning |
| Sketchbooks and art journals | 160+ GSM | Markers, dry media, and light washes | Buckling, surface grain, absorption, and binding feasibility |
These ranges are starting points rather than guarantees. Paper sizing, coating, fibre composition, ink load, and surface finish must also be tested. Format examples in Labon’s notebook and planner portfolio include the Labon Classic Hardcover PU Notebook, Diamond Grid Planner, and Sunrise Journal. Buyers can use these products as format references, then confirm the final GSM separately during sampling.

Paper Specification Checklist Before Ordering
Before requesting a quotation, provide the finished notebook size, orientation, total printed pages, target GSM, paper material, paper colour, ruling, intended pen or art medium, binding method, cover material, logo process, order quantity, individual packaging, carton requirements, and destination market. The approved sample should be checked for bleed-through, ghosting, feathering, drying time, colour consistency, page turning, spine opening, finished-book weight, and packaging fit. Use the custom notebook enquiry form to submit these specifications instead of requesting a quotation based only on “premium paper” or “thick pages.”
