On average, one medium-sized lemon yields about 3 tablespoons (approximately 44-45 mL) of fresh lemon juice

. This amount can vary depending on the lemon's size, variety, ripeness, and juicing method, with typical ranges from about 2 to 4 tablespoons per lemon

Summary of Lemon Juice Yield:

• Small lemon (around 3 oz): 2-3 tablespoons juice (30-45 mL)

• Medium lemon (4-5 oz): 3 tablespoons juice on average, sometimes 3-4 tablespoons (44-60 mL)

• Large lemon (6 oz or more): 4-5 tablespoons juice (60-75 mL)

Practical Notes:

• For recipes, 1 lemon ≈ 3 tablespoons lemon juice is a good standard conversion.
• Half a lemon typically yields about 1.5 tablespoons of juice

• To maximize juice extraction, roll the lemon on a countertop before cutting and use a citrus juicer or manual squeezing

Thus, if you need a cup of lemon juice (about 240 mL), you would use roughly 5 to 6 medium lemons

. This estimate helps in cooking, baking, and beverage preparation where fresh lemon juice is required.
