Plum converter: whole plums, cups, grams
A recipe says “2 cups sliced plum” or “6 ripe plums” but plums run from tiny to plump. Convert between whole plums and sliced cups, grams, or ounces so a tart or compote gets the right amount. A medium plum is about 66 g, so the count shifts as size changes.
A small plum is under half the weight of a large one, so “six plums” in a crumble can swing the fruit volume a lot. Setting the size below keeps tarts, jams, and compotes on target.
How much does a plum weigh?

Plum varieties and best uses
The conversions above are the same whatever variety you use; the difference is what each is good for. Here is how the common plum varieties compare.
| Variety | Best for |
|---|---|
| Red | All-purpose eating and baking: juicy with balanced sweet-tart flesh; the standard supermarket plum (e.g. Santa Rosa). |
| Yellow | Fresh eating and light desserts: very sweet and mild with low acidity and golden flesh (e.g. Mirabelle, Shiro). |
| White | Delicate fresh eating: pale skin and flesh, soft and gently sweet with low acid; bruises easily. |
| Black | All-round cooking and eating: deep purple-black skin and sweet amber flesh that holds up roasted. |
| European (Prune) | Jam, baking, and drying: small, firm, dense freestone with high sugar; the prune and Damson type. |
Which should I pick?
For everyday eating and baking, a Red plum like Santa Rosa is the all-purpose default: juicy, balanced sweet-tart, and widely stocked. No Red plum? A Black plum is an interchangeable all-rounder with deeper colour. For the sweetest fresh fruit reach for a Yellow plum, or a White plum when you want a soft, delicate, low-acid bite. For jam, baking, and drying, a European (Prune) plum is firmest and highest in sugar.
Frequently Asked Questions
- What is the size of a medium plum?
- A medium plum weighs about 66 g, which works out to roughly 0.38 cups (0.4 US cups) of chopped flesh. Plums come in a range of sizes depending on the season, variety and where they were grown, so weight and cup figures shift accordingly. Use the size selector above to match what you actually have, then read the exact conversion for any amount.
- How much does a medium plum weigh?
- A medium plum weighs about 66 g, with a small one around 45 g and a large one near 95 g. That range changes the weight of any recipe that counts plums by the piece, so set the size selector to match what you actually have before trusting a cup or gram figure.
- How much does an average plum weigh?
- An average plum is the same as a medium one: about 66 g. A small plum is lighter at around 45 g and a large one heavier at about 95 g, so the size you actually have changes the total for any recipe that counts plums by the piece rather than by weight.
- How much does a large plum weigh?
- A large plum weighs about 95 g, noticeably more than a medium, or average, one at 66 g or a small one at 45 g. Set the size selector to large to convert cups, grams and ounces for the bigger plums you actually have on the counter.
