Lemons and limes are two of the most popular citrus fruits, and though they look very similar, they have distinct differences in terms of appearance, taste, uses, nutrition, and how they grow.
Quick Facts
Here are some quick facts about the differences between lemons and limes:
- Lemons are yellow, while limes are green.
- Lemons have a more sour taste, while limes are more bitter and tart.
- Lemons are used more often in desserts and beverages, while limes are a key ingredient in many savory dishes.
- Lemons contain more sugar and vitamin C than limes.
- Limes grow better in tropical climates, while lemons grow better in more temperate regions.
Appearance
Though lemons and limes look very similar, there are a few key differences in their appearance:
- Lemons are oval shaped and bright yellow with a glossy smooth skin.
- Limes are smaller and rounder in shape with a green, textured skin.

Taste
Lemons and limes also differ quite a bit in terms of taste:
- Lemons have a sour, acidic taste that is often described as tart and tangy.
- Limes have a bitter, sour taste with a strong citrus flavor.
- Lemons tend to be more sour than bitter tasting.
- Limes tend to be more bitter than sour tasting.
The sourness in lemons comes from their higher citric acid content. Limes contain citric acid too, but also contain other organic acids like malic acid that contribute to their bitter taste.
Acidity Levels
Here is a comparison of the pH and citric acid content of lemons vs. limes:
| Fruit | pH | Citric Acid Content |
|---|---|---|
| Lemon | 2.2 to 2.4 | Approx. 5-6% |
| Lime | 2.0 to 2.2 | Approx. 3-4% |
As you can see, lemons have a higher pH and citric acid content, making them more sour tasting than limes.
Uses
Due to their different tastes, lemons and limes are used in some distinct ways:

Growing Conditions
Lemons and limes prefer different environments when growing:
- Lemons – Grow well in warm temperate climates with sunny, mild winters. Major producers include Spain, Italy, USA, Australia, South Africa.
- Limes – Require tropical climates with high heat and humidity to grow well. Major producers include Mexico, Brazil, India, and Indonesia.
A few reasons for their different climate needs:
- Limes are more cold sensitive – Lemons can still thrive in cooler winter temps that would damage lime trees.
- Limes require higher humidity – Lemon trees are more drought tolerant than lime trees.
- Limes grow best in shade – Lemon trees prefer full sun.
Due to these differences, it can be challenging to grow both lemons and limes well in the same environment. The optimal conditions really depend on the specific type of citrus you are cultivating.
Varieties
There are many different varieties of lemons and limes:
Common Lemons
- Eureka – Most common lemon variety, grown year-round.
- Lisbon – Sweet thin-skinned fruits used mostly for juicing.
- Meyer – Sweeter, more floral lemon-orange hybrid.
Common Limes
- Persian – Most widely used lime, has seedless and seeded varieties.
- Key lime – Smaller, more acidic lime popular in pies.

Price
On average, limes tend to be more expensive than lemons. Here are some average prices in the U.S.:
| Fruit | Average Price |
|---|---|
| Lemons | $1.00 – $2.00 per pound |
| Limes | $2.00 – $3.00 per pound |
Why are limes often more expensive? A few potential reasons:
- Higher production costs – Growing limes is generally more labor intensive than lemons.
- Lower production – Weather issues sometimes decrease lime supply.
- Higher demand – Limes are extremely popular for Mexican cuisine in the U.S.
- Import costs – Most limes in the U.S. are imported, adding to costs.
Of course prices can vary a lot depending on location, season, and shortages. But in general, limes require more care and cost more per pound than lemons.
Substitutes
Lemon and lime juice contain similar acids that provide tangy flavor to dishes. In a pinch, you can substitute one for the other, though it will change the flavor profile a bit:
- In savory dishes – Use lemon juice when you don’t have lime juice, or vice versa.
- In desserts and sweets – Limes can work, but lemons are ideal.
- Consider tweaking other ingredients to balance the flavor.
- Can also substitute vinegar or citric acid solution.
You can’t always swap lemon and lime zest, as the peel contains oils that impact flavor. But the juices can be substituted when only one type of fruit is on hand.
