Smoothie Ratio Calculator

Calculate smoothie ingredients by serving size.
Returns liquid, frozen fruit, greens, protein, and fat amounts using the 2:1:1 liquid-to-fruit formula.

Smoothie Recipe

The perfect smoothie follows a simple ratio that balances taste, texture, and nutrition. The golden ratio for a well-blended smoothie is:

Base ratio (per serving):

  • 1 cup liquid (240 ml), the foundation for blending
  • 1.5 cups fruit (225 g), provides sweetness and flavor
  • 0.5 cup vegetables (40 g), adds nutrients without overpowering taste
  • 1 tablespoon protein/fat (15 g), for satiety and nutrition
  • 0.5 cup ice (optional), for thickness and chill

Liquid options: Water, milk, almond milk, oat milk, coconut water, or juice. Thicker liquids (yogurt-based) may need slightly more volume.

Fruit choices: Bananas are the best base for creaminess. Frozen fruits eliminate the need for ice and create a thicker texture. Popular combinations include banana + berry, mango + pineapple, and peach + banana.

Vegetable additions: Spinach and kale are the most common. Spinach has a milder taste and blends smoother. Start with small amounts if you are new to green smoothies.

Protein sources: Protein powder, nut butter, Greek yogurt, chia seeds, hemp seeds, or silken tofu. Each adds different texture — nut butters make it creamier, seeds add thickness.

Smoothie styles:

  • Green smoothie: extra vegetables, less fruit
  • Protein smoothie: double protein, less fruit
  • Tropical: coconut water base, mango, pineapple
  • Berry blast: mixed berries, banana base

Tips: Always put liquid in the blender first. Add soft ingredients before hard ones. Frozen fruit works better than fresh + ice. Blend for 30–60 seconds on high for smooth consistency. One serving is approximately 450–500 ml (about 16 oz).
