Not all heroes wear capes. Some of them very simply help us find answers to questions that we all thought about, but never quite know how to solve it. Our hero today, Facebook user Jeremy Tan, used his mathematical skills and help from his family to do a bubble tea cup sizes comparison to answer this million-dollar question:

Is it really worth it to upsize your bubble tea?

Is buying the large size really more wuhua?

On Saturday (21 September 2019), Tan posted a video of him doing a bubble tea cup sizes comparison. The bubble tea was bought from seven popular bubble tea outlets, namely – R&B Tea, The Alley, Koi, ShareTea, Gongcha, Liho, and Playmade.

He used the medium and large sizes for comparison, and concluded his findings based on the percentage change in price per litre.

Being very scientific and impartial, Tan put out a disclaimer that stated he had assumed each cup would have the same amount of ice.

Hence, all volumes are the actual volume of the cups.

This was what he meant, and how he did his experiment.

His results?

Do numbers scare you?

Because all this data is killing my brain cells. But let me kill more (of my own) by attempting to summarise the findings for you.

Tan also brought the most expensive and the cheapest drink to make sure he covers all bases.


All the SESes can benefit. Very scientific indeed.

And here’s the simple result:

Most Worth It Overall: The Alley and Koi

Both the cheap and expensive options have a low percentage change in price compared to other brands.

Least Worth It Overall: R&B

The percentage change in price for both options are just… let’s just say I regret the times I upsized at R&B. By the way, Tan used R&B cups in his demo video. My jaw dropped when I watched it. I almost cried.


Here, watch it again:

Most Worth It Drink: Liho’s Golden Avocado Milk

Least Worth It Drink: R&B’s Milk Tea

So what’s the conclusion?


Tan actually summed it up very well, but I’ll sum up his summary in case you can’t see his summary that’s summed up very goodily.

  1. Upsize only when you’re getting the more expensive options.
  2. Never upsize if you’re getting the cheapest item.
  3. Never upsize at R&B.

To be honest, how many of us really care about the price when we buy our bubble tea? Maybe I’m going to sip on it the whole day so I need the upsize.

Who knows. Not as if realising our usual order is the least worth it one will stop us from ever buying it again.

So, take it with a pinch of salt and pepper? Just buy what you want. Happy can already.


But still, swee lah, Jeremy Tan.
