32oz deli cups are around 5.5" tall with a 4.5" wide lid. They are very common in the hobby as a cheap housing option for nymphs or small species, and are also used for large fruit fly cultures.
The plastic is thin enough that you can easily poke holes or cut out sections if you wish to add extra side ventilation.
