What 100 Calories of Nuts Looks Like
Nuts have a reputation for being healthy — but also for being one of those foods that’s surprisingly easy to overeat. And honestly? Once you see what 100 calories of nuts actually looks like, that reputation starts to make a lot of sense.
I used to grab a handful of mixed nuts without thinking much about it, assuming a handful was a handful. But there’s a big difference between 25 pistachios and 3 brazil nuts — and both of those are 100 calories. The range is wider than most people expect.
Whether you’re keeping an eye on portions, building smarter snacking habits, or just genuinely curious about what you’re eating, this list lays it out as clearly as possible. Each nut, weighed out to exactly 100 calories, with no guesswork involved.
Some of these will surprise you with how little you get. A couple might surprise you with how much.

1. Almonds
About 14 raw almonds — roughly 17 grams — lands right at 100 calories, making them one of the most popular and protein-friendly ways to snack smart. Crunchy, filling, and loaded with vitamin E, it’s a surprisingly small handful for such a nutritious punch.

2. Cashews
Just 10 cashews — about 18 grams — will get you to 100 calories, making them one of the creamier, more indulgent-feeling nuts at this count. Rich in copper and magnesium, they’re a satisfying option that feels more like a treat than a diet snack.
3. Walnuts
About 8 walnut halves — roughly 15 grams — hits the 100-calorie mark, making them one of the smallest-looking portions on this list. What they lack in volume they make up for in omega-3 fatty acids, making them one of the most brain-friendly nuts you can eat.

4. Pecans
Around 10 pecan halves — approximately 14 grams — comes in right at 100 calories, a deceptively small serving for such a rich, buttery nut. Pecans are among the most calorie-dense nuts, so that handful disappears fast — but the antioxidants and healthy fats make every bite count.
5. Pistachios
A generous 25 pistachios — about 17 grams — lands right around 100 calories, making them one of the best nuts for sheer volume and snacking satisfaction. Their naturally lower calorie count per nut means you get more to eat, which is why they’re a favorite for mindful snackers.
6. Macadamia Nuts
Only 6 macadamia nuts — around 14 grams — reaches 100 calories, making them the most calorie-dense nut on this list. Buttery, rich, and deeply satisfying, they’re a luxurious snack — just one you’ll want to count out carefully.
7. Brazil Nuts
A mere 3 brazil nuts — roughly 15 grams — is all it takes to hit 100 calories, which makes for a striking visual when placed next to a pile of pistachios. They’re one of the richest dietary sources of selenium on the planet, meaning just a couple a day is genuinely enough.
8. Hazelnuts
About 11 hazelnuts — approximately 16 grams — comes in at 100 calories, a modest but satisfying little pile that’s as nutritious as it is delicious. Packed with vitamin E and heart-healthy monounsaturated fats, they’re the nut behind your favourite chocolate spreads — just in a much more wholesome form.

9. Peanuts
Around 17 peanuts — roughly 17 grams — gets you to 100 calories, one of the more generous counts for a nut at this number. Technically a legume, peanuts are treated like nuts in virtually every kitchen and snack aisle — and with good reason, given their high protein content and satisfying crunch.
10. Pine Nuts
A surprisingly large pile of about 90 pine nuts — around 15 grams — hits the 100-calorie mark, making them one of the most visually impressive entries on this list. Small but mighty, these delicate little seeds are the secret ingredient in traditional pesto and a rich source of manganese and vitamin K.
