5.1 is a standard box size where I live. I’d recommend three 1 oz boxes + one 2.1 oz box to get the same weight.

I cannot find 5.1 oz boxes of instant pudding. The large boxes are 2.1 oz and small boxes are 1oz. Was this a typo, or are there 5.1 oz boxes?

Hi Carol. I think you’re reading the size of the box of pudding. It’s one regular size box, made with 2 cups of milk. I hope this helps.

That’s a single 5.1 oz package of vanilla instant pudding. I can see how the way the measurement is written is confusing — thanks for the feedback and hope this helps!
