Your inputs

How it works

  1. 1

    Enter the total liquid volume of your smoothie in milliliters.

  2. 2

    Rate the current thickness on a scale from 1 (very thin) to 10 (very thick).

  3. 3

    Set your desired thickness on the same 1-10 scale.

  4. 4

    The calculator estimates the grams of thickener (like banana or yogurt) to add.

Frequently asked questions

What counts as a thickener?

Common thickeners include banana, Greek yogurt, oats, chia seeds, or avocado. Use the gram estimate as a starting point and adjust to taste.

Why is the thickness scale 1-10?

It's a simple subjective scale to quantify consistency. 1 is watery, 5 is medium, 10 is very thick like a milkshake.

Can I use this for any smoothie?

Yes, it works for any fruit or vegetable smoothie. Adjust the amount based on the specific thickener's power.

Formulas

The math behind this calculator, written out so you can verify the result.

Thickener amount

Thickener (g) = Liquid volume (ml) × (Desired thickness − Current thickness) / 10

The difference in thickness levels is scaled by the liquid volume to estimate how much thickener to add.

Real-world use cases

Where this calculation shows up in everyday life.

Adjusting a too-thin smoothie

When your smoothie is runny, quickly estimate how much banana or yogurt to add.

Example: 250 ml, current 4, desired 8 → 100 g

Meal prep consistency

Ensure every batch of your favorite smoothie has the same thickness.

Example: Use the same liquid volume and thickness ratings each time.

Tips and common mistakes

Tips

  • Start with half the suggested amount and blend, then add more if needed.
  • Frozen fruits like berries or mango also thicken smoothies naturally.
  • For a thicker result, use less liquid or add ice.
  • The scale is subjective; calibrate it to your own preference.

Common Mistakes to Avoid

  • Using the calculator for dry ingredients like protein powder, which have different thickening properties.
  • Ignoring the effect of ice or frozen fruit, which also add thickness.
  • Assuming the relationship is linear for extreme differences; adjust gradually.

Assumptions and limitations

  • Use the stated inputs and units.
  • Results are estimates for planning and education.
  • Check measurements and source data before making an important decision.
