Dot Grid Spacing for Notebook Inserts: 5mm vs 0.2 Inch
A sourced table of real notebook dot spacings, the exact arithmetic behind 5mm vs 0.2in drift, and why dot size and dot darkness are two separate settings, not one.
If you are printing your own dot grid paper to slot into an existing notebook, “5 mm dots” is not quite enough information. Some generators default to 0.2 inch instead, which sounds identical and is not. Some notebooks are not 5 mm at all. And two sheets with the exact same spacing can still look completely different depending on how big the dots are and how dark. Below: what notebook brands actually use, the arithmetic behind the metric/imperial mismatch, and dot size versus dot darkness — where most home-printed inserts actually go wrong.
What actual notebooks use: a sourced spacing table
“5 mm” gets repeated so often as the bullet journal standard that it is worth checking where the number comes from, rather than assuming every dotted notebook matches. Here is what we could verify, with a source for each figure:
| Brand / product | Dot spacing | Source |
|---|---|---|
| Leuchtturm1917 (Dotted ruling) | 5 × 5 mm | Leuchtturm1917’s own FAQ page, which states the Dotted ruling as “dots with 5 x 5 mm spacing” |
| Rhodia dotPad / Rhodiarama | 5 mm | Rhodia’s dotPad product description and retailer spec sheets (JetPens) |
| Midori MD Notebook (Dot Grid) | 5 mm | Retailer spec sheets for the MD Notebook dot-grid edition (JetPens, Galen Leather) |
| Baron Fig Confidant | 5 mm | JetPens product listing, cross-checked against a side-by-side review that measured the dots against a Leuchtturm1917 and a Rhodia on the same photo (The Well-Appointed Desk) |
| Scribbles That Matter | 5 mm | All About Planners’ page-layout measurements, which also record the printed margins (5.5 mm from the side edges, 7 mm top and bottom) |
| Archer & Olive | 5 mm | All About Planners’ measured page layout (4 mm side margins, 7 mm top/bottom) |
| Dingbats* Notebook | 5 mm | All About Planners’ measured page layout |
| Nuuna | 3.5 mm | All About Planners |
| Happy Notes (me & my BIG ideas) refill | 4.5 × 4.5 mm | All About Planners |
| Agendio (custom-built journals) | 0.25 in (6.35 mm) | Agendio’s own grid option, as recorded in an All About Planners review of a custom order |
| Field Notes (Dot-Graph edition) | 3/16 in (≈4.76 mm) | Field Notes’ own product specification |
| Moleskine (Dotted) | Widely reported as 5 mm by retailers and reviewers | JetPens and multiple retailer listings — Moleskine does not publish an official dot-pitch figure on its own spec sheets, so treat this one as well-corroborated rather than manufacturer-confirmed |
Two things stand out. First, 5 mm really is the majority choice, which is why it is the default here. Second, it is not universal: Nuuna runs noticeably tighter at 3.5 mm, Agendio offers a full quarter-inch, and Field Notes’ Dot-Graph edition sits on an imperial fraction that does not convert to a round metric number at all. If you are refilling a specific notebook, measure ten dots with a ruler and divide by ten rather than trusting a brand-wide assumption — specs also change between print runs, which we come back to at the end.
Where 0.08 mm per cell becomes 3.2 mm across a page
This is the mismatch that catches people out: 0.2 inch is not 5 mm. It is 5.08 mm. That 0.08 mm gap looks like rounding noise — smaller than the width of a fine pen line — until you multiply it across a page instead of a single cell.
This is arithmetic, not a measurement we took off a printed sheet: over 10 cells the drift is 10 × 0.08 mm = 0.8 mm, still easy to miss. Over 40 cells — roughly the number of rows down an A5 page at this spacing — it is 40 × 0.08 mm = 3.2 mm. Over the full width of an A4 sheet (around 41 cells at 5 mm) you get a comparable 3–4 mm of accumulated offset by the far edge.
Three millimeters does not matter if the page stands alone. It matters if you are printing an insert to sit behind, or be compared against, something already fixed: a stencil cut to true 5 mm, a pre-printed page in the same notebook, a ring-bound cover with punched holes at known positions, or the next page in the same pad if you generated it in two batches at two different spacing values. At the edge of a 40-row page, dots specced at 0.2 inch will have visibly walked away from dots specced at 5 mm, even though a single cell of either looks indistinguishable next to a ruler. To match a specific notebook from the table above, enter the metric figure directly rather than “the imperial equivalent” — 5.00 mm, not 0.2 in, when the source says millimeters.
Same 5 mm spacing, different-looking dots
Spacing tells a printer where dots go. It says nothing about how big they are or how dark — genuinely separate decisions, not two ways of describing one setting.
Size and darkness fail independently. A dot that is too large starts acting like a small period: it interrupts a thin pen stroke and gets visually “used up” by anything drawn near it. A dot that is too small or too pale can vanish entirely under warm lighting, which defeats the point of having a grid at all. The two also interact with your printer technology differently. Inkjet ink spreads slightly into paper fibers after it lands — printer manufacturers call this dot gain — so an inkjet dot commonly prints a little larger and softer-edged than the file specifies, especially on uncoated paper. Laser toner fuses onto the surface rather than soaking in, so it prints closer to the nominal size but can look flatter and more uniformly dark, with less of the gentle grey some people want from a “guide, not a grid.” Neither is wrong; they are different physical processes producing different marks from the same PDF geometry.
This is also why identical spacing does not mean identical dots across brands. One side-by-side comparison of a Leuchtturm1917, a Rhodia, and a Baron Fig Confidant — all specced at 5 mm — found the Leuchtturm had the smallest dots, the Baron Fig’s were larger but lighter, and the Rhodia’s were “the darkest and most obtrusive” of the three (The Well-Appointed Desk). Spacing was a constant; size and darkness were not, and that is what actually drove how each page looked and felt to write on.
That is why our own dot grid generator exposes dot size and dot darkness as two separate controls rather than one “grid strength” slider, matching how the site’s printable paper and graph paper tools keep line weight and line opacity apart too. To make dots disappear once you start writing, drop the darkness first and keep the size steady. If a pale, small dot prints patchily, that is usually a minimum-ink-drop problem — the fix is a slightly larger dot at the same darkness, not a darker one at the same tiny size.
Printing A5 inserts without silently rescaling the grid
A5 is the size most bullet journals use, and it is exactly half of A4 by area — but that also makes “fit to page” a trap here specifically. Scaling an A4-drawn PDF down to fit an A5 sheet does not halve the page cleanly; it shrinks every dimension by a factor of 1/√2, about 70.7%, because A5 shares A4’s proportions rather than its size. A 5 mm dot grid built for A4 and then “fit” onto A5 output comes out at roughly 3.5 mm — coincidentally close to Nuuna’s spacing above, and nothing like the 5 mm page it was meant to match. The right way is to generate the page at A5 in the first place and print it at Actual size or 100%, or to print two true A5 pages imposed onto one A4 sheet and trim or fold them apart. We’ve covered the actual-size mechanics — turning off Fit, matching the paper tray, checking driver-level scaling — in full in the printing guide; it applies here without any dot-grid-specific changes.
Paper weight and bleed-through: the next problem after spacing
Once spacing, size, and darkness are settled, paper is the next thing every reader runs into. Standard home printer paper is commonly 80 gsm — and so, notably, are Leuchtturm1917’s and Rhodia’s own notebook papers, so a well-calibrated inkjet or laser sheet is not automatically thinner than the notebook you are matching. Brands that market themselves specifically on resisting fountain-pen bleed-through, like Scribbles That Matter, go up to 160 gsm — past what most consumer inkjets feed reliably without a manual tray, so check your printer’s maximum supported gsm before buying heavier stock. Moving from 80 gsm to 100–120 gsm on a printer that supports it will noticeably cut show-through from felt-tips and fountain pens; it will not replicate the surface sizing dedicated notebook paper uses to control ink spread, and we have not run controlled bleed tests to give a number beyond that.
What changes between editions, and what a printed insert can’t replicate
Two honest limits are worth stating plainly. Manufacturers revise notebooks between print runs without much announcement — a spacing or margin figure accurate when a reviewer measured it can drift slightly in a later batch, so treat every figure above, ours included, as “true as of the source cited” rather than permanent. And no home-printed insert, however precisely spaced, will match a manufactured notebook’s paper weight, binding, or lay-flat behavior — you are matching a grid, not rebuilding the product. If matching an existing notebook is the goal, the reliable habit is the one from earlier: measure your own copy with a ruler and enter that number directly, rather than a brand name or a “5 mm ≈ 0.2 in” shortcut. For denser layouts like a habit tracker that need the grid square across many rows, that same discipline — real millimeters in, real millimeters out — matters even more than it does for one journaling page.
