* ActingForTwo: Creator/MiyukiSawashiro plays both the Landlady and Yuno's classmate Mami.
* BadExportForYou: The Sentai Filmworks releases, at least for the first season and possibly others, contain a mix of broadcast and disc versions of the episodes.
* BreakthroughHit: While not the first work (nor the most iconic) of either, ''Hidamari Sketch'' is credited as the first major success for both Magazine/MangaTimeKirara and Creator/StudioShaft. It was the first anime adaptation from the former that would pay the way for most of its later manga to get animated, and it's recognized as the latter's first series to adapt the studio's signature style. And all this after it survived an infamously troublesome production.
* ExecutiveVeto: [[WordOfGod Aoki]] wanted Hiro to be a male WholesomeCrossdresser, but was shot down by her editor.
* FollowTheLeader: Due to the success of ''Hidamari'', Kirara would start to branch out into adapting more of their manga, which is still seen to this day. Most of them follow the same SchoolgirlSeries template as ''Hidamari'', but a majority have failed to recapture the same magic.
* LateExportForYou: The Graduation Arc OVA was released in Japan in 2013. It came to North America in 2022, ''nine years later''.
* NoBudget: Famously, the first season was made on an incredibly cheap budget, given it was in the early days of Kirara and Shaft (the former which had never dabbled in anime prior and the latter only produced a few anime beforehand). This turned out to be a blessing as the unique direction the first season brought to the table has been praised as one of its best qualities. The following seasons were given a larger budget and more polish.
* PortmanteauSeriesNickname: [=HidaSketch=].
* SeriesHiatus: The series used to be regularly active in its prime during the heyday of the anime, but the manga has been infrequent with chapters ever since the anime ended. The volume releases reflected this; from 2005 to 2012, there were seven volumes distributed. From 2013 to 2020, only three volumes were released, and that's not taking into account the four-year gap between the ninth and tenth volumes.
