If you’ve ever finished a page of notes only to see the ghost of your last paragraph bleeding through the other side, you already know the difference between premium and budget A5 notebook paper. That translucent mess is exactly what a higher grammage (grams per square meter, or gsm) rating prevents. The right A5 paper blends a precise weight with the correct ruling, hole pattern, and surface texture so your fountain pen, gel ink, or marker glides without feathering on side one and leaves side two perfectly legible.
I’m Min — the co-founder and writer behind Gadgets Feed. I’ve spent countless hours comparing paper density, ink resistance, archival pH levels, and ruling formats across dozens of A5 loose-leaf brands to pinpoint the refills that survive real daily use.
Whether you’re refilling a Filofax, a Kokuyo Campus binder, or a custom traveler’s notebook, the following guide covers the only best a5 notebook paper options worth your consideration this season.
How To Choose The Best A5 Notebook Paper
The single most important spec on any A5 refill pack is its grammage, measured in gsm (grams per square meter). A 70gsm sheet is thin, economical, and prone to ghosting; 80gsm is the standard for copy paper and many notebooks; 100gsm or higher enters bleed-proof territory, especially critical for fountain-pen users. After grammage, look at the ruling density — lined, dotted, or grid — and the hole configuration (6-hole for Filofax-style planners vs. 20-hole for Kokuyo Campus binders).
Grammage and Ink Resistance
Paper below 80gsm will almost always show ink on the reverse side when used with wet writers like fountain pens or brush markers. Jumping to 100gsm virtually eliminates show-through and ghosting, making both sides of the sheet usable. Some premium Japanese papers employ a special ink-resistant coating at 75gsm, offering exceptional performance at a lighter weight. pH-neutral (acid-free) paper also resists yellowing over years, a key consideration for archival notes and journals.
Ruling Styles and Hole Patterns
Lined paper with 6mm or 7mm spacing works best for general writing and meeting notes. Dotted ruling gives you the freedom to draw lines, tables, and diagrams without the rigidity of full grid paper. Grid ruling (5mm or 6mm) is the choice of bullet journalists, engineers, and anyone who draws or sketches. The hole pattern must match your binder: most A5 planners (Filofax, Kikki.K, Van der Spek) use the standard 6-hole layout, while Kokuyo Campus binders require 20 holes. Always confirm the hole count before buying.
Sheet Count and Color Options
If your binder holds only 80–100 sheets, a 3-pack of 300 sheets is practical. For high-volume note-takers, single packs with 960 sheets save reordering time. Colored paper adds visual organization — perfect for separating projects in the same binder — but often uses a lower grammage, so check for bleed-through before committing. Vintage-tinted paper (cream, pastel) reduces contrast and eye strain compared to bright white, though at the cost of slightly duller ink colors.

In‑Depth Reviews
1. Nokingo 3-Pack A5 Dotted Refills (300 Sheets, 100gsm)
The Nokingo dotted pack hits the sweet spot between weight and price with its 100gsm stock. Users report zero bleed-through even when sharpies, Micron pens, and lighter Tombow markers are used — the paper is opaque enough to keep both sides usable. The 5.8 x 8.2 inch size matches true A5 dimensions, so it seats perfectly in standard 6-ring Filofax, Kikki.K, and Gillio binders without overhang.
The dotted ruling is subtle and dark enough to guide layouts without overpowering handwriting or sketches. This makes it an excellent choice for bullet journaling, habit tracking, or creative scrapbooking where both structure and freedom matter. The 3-pack yields 300 sheets (600 pages total), enough to last months of consistent use.
A handful of users noted occasional stained pages in their batch, but the overwhelming consensus praises the bright white color, the smooth but not slippery texture, and the fact that holes align flawlessly with 6-ring mechanisms. If you need a versatile dotted paper that won’t ghost under wet ink, this is the benchmark.
Why it’s great
- 100gsm eliminates bleed-through with most fountain and gel pens.
- True A5 dimensions fit 6-ring planners without trimming.
- Dotted ruling works for journaling, sketching, and planning.
Good to know
- Occasional quality-control variances (stained pages) reported.
- Texture feels closer to copy paper than premium Japanese stock.
2. Kokuyo Campus Sarasara Dotted 3-Pack (300 Sheets, 75gsm)
Kokuyo’s Sarasara (smooth) paper proves that you don’t need 100gsm to resist ink. At 75gsm, this Japanese paper uses advanced surface sizing to prevent feathering and bleed-through with fountain pens, shimmer inks, and highlighters. Many fountain pen enthusiasts confirm that sheening and shading still display vividly with minimal ghosting — a rare feat at this grammage.
The 6mm dotted ruling is faint but visible, offering guided note-taking without the rigid feel of full lines. The 20-hole pattern is designed for Kokuyo Campus binders, so it will not fit Filofax-type planners without adapters. The 3-pack provides 300 sheets total, and the paper is pH-neutral for archival storage.
If you value a smooth, low-resistance writing feel and use a Kokuyo binder, this is arguably the best writing experience of any A5 paper in this list. The sheets are slightly thinner than the Nokingo, but the ink-resistant coating compensates so well that most users never notice a difference in opacity.
Why it’s great
- Exceptional fountain pen performance at a lighter 75gsm weight.
- Sarasara smooth surface minimizes writing friction.
- pH-neutral paper resists yellowing over time.
Good to know
- 20-hole pattern limits compatibility to Kokuyo Campus binders only.
- Thinner sheets may not suit heavy marker use as well as 100gsm.
3. Nokingo 3-Pack A5 Lined Refills (300 Sheets, 100gsm)
This lined variant from Nokingo offers the same 100gsm, acid-free paper as its dotted sibling but with crisp 6mm black ruling. The lines are printed double-sided and visible without being intrusive, making it a straightforward refill for anyone who prefers structured note-taking. Users confirm that gel pens, rollerballs, and fountain pens produce no bleed-through, and the paper holds up to regular erasing without tearing.
The 6-hole pattern aligns perfectly with Filofax A5 organizers, Kikki.K large binders, and most standard A5 ring planners. Each pack contains 100 sheets, and the 3-pack totals 300 sheets (600 pages). The paper is bright white with a smooth finish that prints well on inkjet if you need to insert pre-printed pages.
At the same price point as the dotted version, this lined pack is the go-to for anyone who prefers traditional ruled lines for meeting minutes, class notes, or to-do lists. The thickness (100gsm) ensures there is no show-through even with heavy handwriting pressure.
Why it’s great
- Same 100gsm bleed resistance as the dotted version at a low cost.
- 6mm ruled lines keep writing uniform and organized.
- Standard 6-hole design fits most A5 planners out of the box.
Good to know
- No ruling variety offered (lined only in this pack).
- Paper feels similar to premium copy paper, not luxury stationery.
4. Kokuyo Campus Sarasara Grid 5-Pack (300 Sheets, 75gsm)
Kokuyo’s 5mm grid ruled paper in the Sarasara finish is the top choice for precise note-taking, math work, drawing, and bullet journaling. The 5mm squares are fine enough to subdivide for graphs or diagrams, yet visible enough to keep text aligned. The paper packs 60 sheets per pack, with 5 packs totaling 300 sheets.
Like the dotted Kokuyo variant, this grid paper uses the same 75gsm Japanese stock with ink-resistant technology. Users consistently report that fountain pens perform beautifully — crisp letters, vibrant colors, and minimal feathering. The pH-neutral composition ensures the paper remains white and intact for years, making it ideal for archival projects.
The 20-hole pattern again restricts compatibility to Kokuyo and Campus binder systems. However, for anyone already using a Campus binder, this is the definitive paper: the 5mm grid gives you total layout flexibility, while the smooth Sarasara surface allows fast, effortless writing.
Why it’s great
- 5mm grid perfect for technical notes, sketching, and structured layouts.
- Kokuyo’s ink-resistant coating delivers fountain-pen-friendly performance at 75gsm.
- Acid-free paper lasts without yellowing or embrittlement.
Good to know
- Only fits 20-hole binders (Kokuyo Campus system).
- 60 sheets per pack means less value per pack than bulk alternatives.
5. OKWUYiK Watercolor A5 Lined Refills (300 Sheets, 100gsm)
For those who find plain white paper dull, the OKWUYiK watercolor refills bring a soft, artistic gradient to every page. Each of the 300 sheets features a watercolor pattern — four colors, 75 sheets per color — that adds visual interest without overwhelming handwritten content. The paper maintains 100gsm thickness, so gel pens, fountain pens, and highlighters don’t bleed through.
The lined ruling follows standard 9/32-inch spacing, making it compatible with typical planning and note-taking workflows. The 6-hole pattern fits standard A5 binders, and the double-sided design ensures you can use both sides without pattern interference. Users note that the colors are subtle enough for professional notes yet engaging enough for creative journaling.
This is not the cheapest option per sheet — the colored print adds cost — but it is one of the most visually distinctive options for anyone who wants their planner or diary to stand out. The paper’s smooth surface handles erasing well and supports stickers and washi tape without tearing.
Why it’s great
- Unique watercolor patterns make each page memorable and artistic.
- 100gsm ensures no ghosting or bleed-through.
- Four distinct colors help categorize notes visually.
Good to know
- Colored print raises per-sheet cost compared to plain white paper.
- Pattern may not suit very formal or minimal aesthetic preferences.
6. PerKoop 12-Pack Vintage Lined Refills (960 Sheets)
The PerKoop 12-pack delivers an astonishing 960 sheets in 12 different vintage colors, making it the highest-volume pack in this guide. The paper is thinner than the 100gsm options — users describe it as “not bulky but sturdy” — yet gel pens, fountain pens, and standard ballpoints do not bleed through. The vintage color palette (mustard, sage, rose, lavender, etc.) provides an excellent system for color-coding projects, meeting notes, or daily agendas without relying on sticky tabs.
Each sheet measures 5.8 x 8.2 inches and features the standard 6-hole layout for universal A5 binder compatibility. The ruled lines follow conventional college spacing (9/32 inches apart), so writing stays neat. Users have successfully used these sheets for DND journals, work planning, and scrapbooking, noting that the paper is sticker- and washi-tape-friendly.
The main trade-off is the lighter grammage: while it holds ink well, it does not provide the same luxurious feel as 100gsm paper. However, for sheer volume, affordability, and organizational color-coding, the PerKoop pack is unmatched. It is also a strong charitable option as the brand ties a portion of sales to Operation Christmas charity.
Why it’s great
- 960 sheets provide the highest page count of any option here.
- 12 vintage colors enable effortless visual organization.
- Standard 6-hole design fits most Filofax-style binders.
Good to know
- Paper is thinner than 100gsm options; some transparency possible.
- Not ideal for heavy wet media like brush pens or alcohol markers.
