A 12 fl oz can of regular Dr Pepper has 150 calories and 39 g of sugar (all of it added sugar), with 0 g of fat and about 55 mg of sodium. A 20 fl oz bottle jumps to 250 calories and roughly 64 g of sugar. Diet Dr Pepper and Dr Pepper Zero Sugar have 0 calories and 0 grams of sugar.
As much as fans love this drink, the sugar is real. One regular can already pushes past the daily added-sugar limits that the American Heart Association recommends. So here is the full nutrition picture by serving size, what that sugar means in plain terms, and the zero-sugar versions to reach for when you want the taste without the load.
This is general information, not medical or dietary advice. For guidance on your own sugar or calorie intake, check with a doctor or registered dietitian.
Sugar in a 12 oz can, in grams and teaspoons
These are the numbers from Dr Pepper's official product facts for the standard 12 fl oz can:
- Calories: 150
- Total sugar: 39 g (all added)
- Total carbohydrate: 40 g
- Total fat: 0 g
- Sodium: ~55 mg
- Caffeine: ~41 mg (see how much caffeine is in Dr Pepper)
All 39 grams are added sugar, which is the kind health bodies want you to limit. There is nothing nutritionally "earned" here, no fiber or protein offsetting it. It is sweetness and caffeine. For the complete panel with the daily-value percentages and the ingredient list, see the full Dr Pepper nutrition label.
Sugar and calories by bottle size
This is the chart every label should print, because the can is not the only way people drink it. The bigger the container, the faster it adds up.
| Serving | Calories | Sugar |
|---|---|---|
| 12 fl oz can | 150 | ~39 g |
| 16 fl oz | ~200 | ~53 g |
| 20 fl oz bottle | 250 | ~64 g |
| 2 L (per 12 oz serving) | 150 | ~39 g |
| ~32 fl oz fountain (with ice) | ~290 to 400 | ~78 to 100+ g |
The fountain range is wide on purpose: ice displaces soda, free refills add up, and cup sizes vary, so a "large" can land anywhere in that band. The honest read is that a 20 oz bottle or a big fountain cup is two to three cans' worth of sugar in one sitting.
What 39 grams of sugar actually means
Thirty-nine grams is about 9.75 teaspoons of sugar, near enough to 10 that it is worth picturing ten teaspoons going into a glass. Here is the part that surprises most people. The American Heart Association recommends a daily added-sugar limit of about 25 g (6 teaspoons) for women and 36 g (9 teaspoons) for men.
That means a single 12 oz can of regular Dr Pepper (39 g) exceeds the entire day's recommended added sugar for both women and men, before you eat anything else. A 20 oz bottle nearly doubles the men's limit on its own. This is not meant to scare anyone off a treat; it just makes the daily-habit math clear. If sugary soda is a daily thing, it adds up fast, and that pattern is exactly what gets flagged in the research covered in is Dr Pepper bad for you.
No, it is not 78 grams of sugar
Two of the results that rank for this question say Dr Pepper contains 78 grams of sugar, or that it is "78% sugar". Both come from misreading the label, and the confusion is worth clearing up because it spreads.
A 12 oz can has 39 grams of added sugar. The 78% on the label is the daily value percentage, which is 39 g measured against the FDA's 50 g reference for added sugar. Someone read the percentage as a gram figure and doubled the real number. If you see 78 g quoted anywhere, that is where it came from.
The 39 g figure is the one printed on the can, and it is confirmed on the Dr Pepper nutrition label.
The zero-sugar swaps
The good news is that the zero-sugar versions are not a watered-down compromise; they are the same brand family with the sugar and calories removed.
- Diet Dr Pepper: 0 calories, 0 g sugar, sweetened with aspartame. For a closer look at what is in it, see what sweetener is in Diet Dr Pepper.
- Dr Pepper Zero Sugar: 0 calories, 0 g sugar, tuned to taste closer to the original than classic Diet.
- Dr Pepper Cherry Zero: the cherry twist with none of the sugar.
These keep the caffeine (about 41 mg, same ballpark as the original) but drop all 150 calories and all 39 g of sugar. For anyone cutting back, swapping the daily can for Zero is often the single change that moves the needle most. If you want to try the swap, you can grab a 12-pack of Dr Pepper Zero Sugar (As an Amazon Associate I earn from qualifying purchases, at no extra cost to you.), pick up Diet Dr Pepper by the 12-pack, or stick with the classic and grab a 12-pack of regular Dr Pepper if you would rather just drink less of it.
How Dr Pepper compares
Calorie and sugar-wise, regular Dr Pepper is in the same neighborhood as other full-sugar sodas. The flavor is the differentiator, built on its 23 flavors, not the nutrition. If you are weighing it against the colas, see Dr Pepper vs Coke vs Pepsi. And if you enjoy it in recipes rather than straight, a Dr Pepper float or one of the other Dr Pepper recipes at least turns the sugar into an occasional treat rather than a daily default.

How many grams of sugar are in a can of Dr Pepper?
39 g in a 12 fl oz can, and every gram of it is added sugar. The 40 g often quoted is the total carbohydrate line, which is the row directly above it on the label. A 20 fl oz bottle has about 64 g and a 2 L bottle works out to roughly 39 g per 12 oz serving.

About 9.75 teaspoons. One teaspoon of granulated sugar is roughly 4 g, so 39 g divides out to just under 10. That is already past the American Heart Association's whole-day added-sugar limit for women (6 teaspoons) and men (9 teaspoons).
Does Diet Dr Pepper have calories or sugar?
No. Diet Dr Pepper and Dr Pepper Zero Sugar both have 0 calories and 0 grams of sugar. They use sugar substitutes instead.
Is Dr Pepper high in sodium?
Not particularly. A 12 oz can has about 55 mg of sodium, which is low compared with most processed foods. The sugar is the number to watch, not the sodium.
The bottom line
A 12 oz can of regular Dr Pepper is 150 calories and 39 g of added sugar, and that single can already exceeds the American Heart Association's daily added-sugar guideline. Bigger sizes scale up fast: a 20 oz bottle is 250 calories and about 64 g of sugar. If you want the flavor without the load, Dr Pepper Zero Sugar and Diet Dr Pepper deliver it at 0 calories and 0 sugar, keeping roughly the same caffeine. Enjoy the real thing as a treat, just count it as one.
