The codex contains the text of the four Gospels, on 204 parchment leaves of size 28.5 × 22 cm (11.2 × 8.7 in), with numerous lacunae (or gaps).
The text of the existing codex begins with Matthew 9:1 and ends with John 13:34.
Luke is even more incomplete.
In 1751 Wettstein remarked that the codex started at Matthew 7:6 and that only the folia with Matthew 8:25 and Mark 11:6–16 were missing.
It means that in his time the manuscript was far more complete than at present.
At present, lacunae of the manuscript include:
Matthew 1:1–9:1; 12:1–44; 13:55–14:9; 15:20–31; 20:18–21:5;
Mark 1:43–2:8; 2:23–3:5; 11:6–26; 14:54–15:5; 15:39–16:19;
Luke – at least 24 gaps;
John 3:5–14; 4:23–38; 5:18–38; 6:39–63; 7:28–8:10; 10:32–11:3; 12:14–25; 13:34-end.

The leaves are unbound and are kept in loose quires.
The text is written in late uncial script, in two columns per page, with mostly 19 lines per column, in large uncial letters.
Palaeographically the writing is close to the Codex Seidelianus I.
The letters Η, Μ, Ν, and Π, are square, the letters Ε, Θ, Ο, Σ, and Φ have a round shape.
The letters Δ, Ε, Θ, Ο, and especially Ψ in cruciform, are of the form characteristic for the late uncial script.
Φ is large and bevelled at both ends.
The letters were written by an 'elegant and careful' hand.

The nomina sacra (or sacred names) are written in an abbreviated way: ΘΣ for θεος, ΙΣ for Ιησους, ΧΣ for χριστος, ΚΣ for κυριος, ΥΣ for υιος, ΣΗΡ for σωτηρ, ΣΡΑ for σωτηρια, ΣΡΙΟΣ for σωτηριος, ΟΥΝΟΣ for ουρανος, ΟΥΝΙΟΣ for ουρανιος, ΠΝΑ for πνευμα, ΠΗΡ for πατηρ, ΜΗΡ for μητηρ, ΑΝΟΣ for ανθρωπος, ΣΤΡΣ for σταυρος, ΔΑΔ for δαβιδ, ΙΗΛ for ισραηλ, ΙΛΗΜ for ιερουσαλημ, etc.
The words at the end of lines are sometimes abbreviated too.
It uses typographic ligatures.

The codex has a lot of grammar errors, like hiatus (e.g. νηστευουσιν in Matthew 9:14, ελεγεν in Matthew 9:21, ειπεν in Matthew 9:22, etc.)
and N ephelkystikon.
The error of iotacism occurs infrequently.

The breathings (rough and smooth breathing) and accents (see e.g. Greek diacritics) are given fully and usually correctly.
The breathings are indicated by sigla ⊢ and ⊣, often used in codices from the 9th and 10th century.
In some cases breathings are given incorrectly (e.g. Matthew 9,7.16).

The text is divided according to the Ammonian Sections, with the usual number of sections, are written on the left margin, but there are given without references to the Eusebian Canons.
There is no division according to the κεφαλαια (chapters), but the τιτλοι (titles) are given at the top of the pages, sometimes also at the bottom.
The capitals at the beginning of the sections stand out in the margin to indicate new sections (as in codices Alexandrinus, Ephraemi, and Basilensis.
Although there is no division according to the κεφαλαια (chapters), the tables of the κεφαλαια (tables of contents) are placed before each Gospel (except Matthew – because of its defective character).
It has some lectionary markings at the margin.

The headpieces are decorated, with headings written in gold and red; in some places nicely decorated initial letters can be found (in red or gold).
The Ammonian sections are written in red.
The pages are numbered; the Greek quire numbers are still found at the top right of some pages.
At the top left of the first page of most quires in Gospel of Matthew, Arabic quire numbers are found.

There are several different correctors, among which the "first hand" worked on the codex, but the total number of corrections is not high.
