- Acting for Two - Miyuki Sawashiro plays both the Landlady and Yuno's classmate Mami.
- Bad Export for You: The Sentai Filmworks releases, at least for the first season and possibly others, contain a mix of broadcast and disc versions of the episodes.
- Common Crossover: Due to the association with Ume Aoki, fans of Hidamari Sketch tend to also like Puella Magi Madoka Magica, which Aoki was the character designer. Considering what kind of story PMMM is, the adjoining of those two is widely disturbing.
- Clearly this has been noted by the producers; a commercial for the Puella Magi Madoka Magica Movie appeared in the first episode of Hidamari Sketch X Honeycomb, aired early October 2012. This is hardly coincidental, as producers purchase the entire Otaku O'Clock block and has a free rein on what commercials to put on as long as it agrees with the Moral Guardians.
- This is also the origin of the Fan Nickname "Chidamari Sketch" for PMMM ("chidamari" meaning, approximately, "pool of blood" in Japanese).
- Executive Veto: Aoki wanted Hiro to be a male Wholesome Crossdresser, but was shot down by her editor.
- Fan Nickname: Wideface for the iconic kind of Super-deformation.
- Portmanteau Series Nickname: HidaSketch.
- Relationship Voice Actor: Ryoko Shintani and Miyuki Sawashiro are together once again.
