Order from largest to smallest:
1. Giant elliptical
2. Spiral
3. Irregular
4. Dwarf elliptical
Notes: giant ellipticals (cD galaxies) can be tens to hundreds of kiloparsecs across, typical large spirals are tens of kpc, irregulars are usually smaller (a few to ~10 kpc), and dwarf ellipticals are the smallest (often ~1 kpc). There is overlap and exceptions (e.g., some irregulars like the LMC are similar in size to small spirals), but this is the typical ranking.
