What the official website uses
Deltarune.com, Toby Fox's official site for the game, loads two web fonts named 8bitOperatorPlus-Regular and 8bitOperatorPlus-Bold from its own servers and uses them as its pixel text style. For Japanese text it loads JF Dot Shinonome 14, another pixel font. This is the most direct evidence we found of the type Deltarune uses for its own text, though a website does not prove what every in-game screen uses.

Regular · Latin specimen
A blocky pixel font with square, even letters, close in spirit to the chunky Deltarune logo. Its lowercase looks like small capitals, and it has no heart detail.

Regular · Latin specimen
A pixel font based on an old computer terminal, good for dialogue-style text. It is taller and narrower than 8-Bit Operator, so it reads more like a screen than a game box.
View fontThe Undertale connection
Fonts In Use, an archive of typefaces in real work, has an entry on Undertale's dialogue and interfaces. It says Undertale uses 8-Bit Operator JVE for narration, overworld dialogue and as the main interface typeface, and that the 8-Bit Operator family is also used for branding and identity for Undertale and its sister game Deltarune. The entry covers Undertale's screens; it does not list Deltarune's in-game fonts.
Evidence for this attribution ↓Who made 8-Bit Operator
Fonts In Use credits 8-Bit Operator JVE to Jayvee Enaguas of Grand Chaos Productions and dates it to 2011. It notes that the font was later superseded by Pixel Operator, a newer pixel family. The archive links the 2011 font on FontStruct. Its typeface page lists one use so far, Undertale's dialogue and interfaces, credited to Toby Fox. It gives no licence terms, so check the file you download.
Evidence for this attribution ↓How to get the look
For text, use a crisp pixel font at whole-number sizes so the pixels stay sharp, white on black, with loose spacing for dialogue. For the logo, build chunky lowercase letters from square blocks and cut a small heart into the a. Silkscreen gets close to the blocky logo; VT323 works for longer dialogue-style text. Keep colours simple: white, black and one accent.
Common questions
Is the Deltarune font free?
The 8-Bit Operator fonts are free pixel fonts, but download sites list different licence terms, so check the licence file before commercial use. The logo itself is not a font. Silkscreen and VT323 are free Google Fonts with a similar pixel look.
What font is the Deltarune dialogue?
We found no reliable source that names the in-game dialogue font of Deltarune. Fonts In Use documents 8-Bit Operator JVE as Undertale's dialogue font and says the family is used in Deltarune branding. Fan-made fonts based on the games exist but are not official.
What font is the Deltarune logo?
No source names one. Wikipedia describes the logo as the word deltarune in a pixelated font, with a heart replacing the hole of the a. We treat it as pixel lettering made for the game.
