Greek slice dishes pack a lot of flavor — and often more calories than you would guess. A triangle of baklava, a wedge of spanakopita, or a square of tyropita can vary by a factor of two depending on how thick the pastry is and how much butter or filling went into it. This calculator turns your portion into a practical calorie estimate using typical nutrition values per 100 grams.
Pick your dish from the dropdown, tell us how many slices you plan to eat, and adjust the slice weight to match your actual portion. A 100 g baseline is a good starting point, but restaurant slices are frequently larger. The tool instantly shows calories per slice, total calories for the meal, and what that represents in a 2,000-calorie day.
Optional macronutrient fields add fat, carb, and protein totals for each slice and for the whole serving — handy if you are tracking macros. It is built for anyone who wants a fast, honest estimate before digging in.

What Counts as a Slice?
Greek slice dishes are rarely standardized. Restaurant spanakopita is often cut into large squares weighing around 150 g, while a homemade slice may be a third of that. Greek-style pizza slices are usually 1/8 of a 14-inch pie, and baklava pieces can range from 30 g to over 60 g. Because of this, the single most useful action you can take is to weigh your portion once and note your usual slice size. From then on, estimating is quick.
How the Calculation Works
The tool uses the standard per-100-gram format found on food labels and in nutrition databases. Once you provide the calories per 100 g for your dish, the math is straightforward:
Total calories = calories per slice × number of slices
The same proportion is used for fat, carbs, and protein when the optional fields are filled in. The daily value percentage is simply your total calories divided by a 2,000-calorie reference diet, multiplied by 100.
Reference Values for Common Greek Slice Dishes
Typical values per 100 g for common Greek slice dishes, based on standard recipes and nutrition databases. Your results may vary with the amount of butter, oil, filo, and filling.
| Dish | Calories | Fat | Carbs | Protein |
|---|---|---|---|---|
| Spanakopita (spinach & feta) | 245 kcal | 16 g | 18.5 g | 6.5 g |
| Tyropita (cheese pie) | 300 kcal | 20 g | 22 g | 8 g |
| Kreatopita (meat pie) | 290 kcal | 17 g | 24 g | 12 g |
| Greek-style pizza | 260 kcal | 11 g | 30 g | 10 g |
| Baklava | 420 kcal | 28 g | 35 g | 6 g |
| Galaktoboureko (custard slice) | 270 kcal | 12 g | 35 g | 6 g |
For bakery-made or packaged versions, check the product label and enter your own numbers using the Custom Greek dish option — that will always beat a generic estimate.
Worked Examples
Example 1 — Spanakopita slice: A 150 g slice with a standard 245 kcal per 100 g: (150 ÷ 100) × 245 = 367.5 kcal, roughly 368 kcal. Two slices would be about 735 kcal.
Example 2 — Baklava piece: An 80 g piece at 420 kcal per 100 g: (80 ÷ 100) × 420 = 336 kcal. A smaller 40 g piece would be about 168 kcal.
Example 3 — Greek pizza: A 200 g slice at 260 kcal per 100 g reaches 520 kcal, before any extra toppings or cheese.
Tips for Better Estimates
- Weigh your slice in grams when possible; volume estimates are unreliable for layered pastry.
- Filo pastry brushed with butter is calorie-dense — a slice that looks light may still be 50–60% fat.
- Restaurant portions are often 30–50% larger than the standard 100 g reference. When in doubt, err upward.
- Use the Custom Greek dish fields when you have a package label or a restaurant nutrition sheet.
- Treat 2,000 kcal as a general reference; your actual needs depend on age, sex, activity, and goals.
Frequently Asked Questions
Why do different sources list different calories for spanakopita? Recipes vary: some use lighter fillings, others heavy feta, whole eggs, and generous olive oil. Commercial brands also differ from restaurant recipes, so a range of 220–280 kcal per 100 g is normal.
Is baklava really that high in calories? Yes, usually. Layers of filo soaked in butter and honey or sugar syrup make baklava one of the most calorie-dense Greek sweets — commonly 400–500 kcal per 100 g.
Can I track just one slice? Of course. Set the number of slices to 1 and adjust the slice weight to match your portion. The calories-per-slice figure is the one to record.
What about homemade versions? Homemade dishes are a perfect fit for the custom mode — enter the calories per 100 g from your own recipe or nutrition app, then use the same slice-weight logic.
