[Google Fonts] · OFL-1.1 · Variable
Contemporary slab with a variable 100-900 axis; closest to Calluna's wedge-slab serifs.
Why it matches: Calluna's defining feature is its serifs — angled, slab-like, and joined to the stem with a bend that Jos Buivenga described as creating direction toward the upper right of each glyph. Bitter is the free face that gets closest to that construction: squared serifs, low contrast, and enough weight in the joins to read as deliberate rather than decorative. Bitter is the colder of the two, drawn for screens rather than for flow, so it loses some of Calluna's warmth. It gains a full variable axis in exchange.

Mozilla's slab; angled cuts and a similar sense of forward motion.
Why it matches: Zilla Slab shares the specific thing that makes Calluna feel like it moves: serifs that are cut at an angle rather than set square, so each letter leans very slightly into the next. Set a paragraph of each and the rhythm is recognisably related. Zilla is more geometric in its underlying skeleton and its counters are more open, which makes it the better performer at display sizes and the weaker one across a long page of text.

[Google Fonts] · OFL-1.1 · Variable
Calligraphic roots and brushed terminals; matches Calluna's warmth if not its slabs.
Why it matches: If what you valued in Calluna was the flow rather than the slabs, Lora is the closer match. Its terminals are brushed rather than cut, its contrast is moderate, and its italic has genuine calligraphic movement — all qualities Calluna was reaching for when Buivenga called it "a text typeface with flow". Lora is a more conventional serif in construction, so it will not deliver Calluna's distinctive descender serifs on the `p` and `q`, but it reads beautifully at length.

Literary serif with calligraphic origins, drawn for extended reading.
Why it matches: Alegreya was designed for literature and it shows — the letterforms carry a visible written origin, the rhythm is slightly irregular in the way handwriting is, and it holds attention across many pages without becoming mechanical. That irregularity is the shared quality with Calluna, which is also a face that resists looking systematic. Alegreya's serifs are conventional rather than slab-like, so the visual match is looser than Bitter's; the reading experience is closer.

[Google Fonts] · OFL-1.1 · Variable
Sturdy, warm text serif with a slightly rustic quality.
Why it matches: Vollkorn is heavier and blunter than Calluna — the name means "wholemeal" and the face is exactly that agricultural — but it occupies the same emotional register: a text serif with obvious personality that still behaves across a full page. Its serifs are chunky and squarish, which puts it nearer Calluna than a refined book face would be. Use it where Calluna was doing warm, slightly informal editorial work.

Old-style book serif; more traditional and higher contrast than Calluna.
Why it matches: Crimson Pro is the choice when Calluna's job was book-like body text and the slab character was incidental. It is an old-style face in the Garamond tradition — finer serifs, higher contrast, smaller x-height — and it reads superbly at length in print. Against Calluna it is quieter and more conventional, and it will not carry a headline the way Calluna's heavier weights can. A straightforward trade of character for classicism.

Screen-first editorial serif with an optical size axis.
Why it matches: Newsreader is the most modern option here and the least like Calluna in shape, but it is the strongest performer if the work is going on the web. It carries an optical size axis, so the same family sharpens for headlines and thickens for body copy — something Calluna, drawn before variable fonts existed, cannot do. Choose it when replacing Calluna is an opportunity to pick up capabilities rather than an exercise in matching a look.
