A perfectly balanced vinaigrette can elevate a simple salad into something memorable, but getting the ratio right between oil and acid is the crucial first step. Too much acid and the dressing is sharp and mouth-puckering; too little and the salad tastes greasy and flat. The classic French ratio of 3 parts oil to 1 part acid has endured in culinary tradition for centuries because it works beautifully across an enormous range of oils, vinegars, and salad ingredients.
The Vinaigrette Ratio Calculator takes your desired total volume and preferred style, and instantly tells you exactly how much oil, acid, and emulsifier to use. Three styles are available: the classic French 3:1 ratio, a brighter, more acidic 2:1 ratio for heartier greens and grain salads, and a creamy emulsified version that adds a portion of emulsifier (Dijon mustard, honey, or egg yolk) to create a stable, creamy dressing that clings to ingredients rather than pooling at the bottom of the bowl.
The choice of oil and acid dramatically affects the final character of the vinaigrette. Extra-virgin olive oil is the classic choice for most vinaigrettes, offering fruity, peppery notes. Neutral oils like grapeseed, sunflower, or avocado oil produce a lighter, less assertive dressing — ideal when you do not want the oil to compete with other flavors. Nut oils (walnut, hazelnut) add a distinctive richness. For the acid component, red wine vinegar, white wine vinegar, Champagne vinegar, sherry vinegar, apple cider vinegar, or fresh citrus juice (lemon, lime, orange) each contribute a different acidity and flavor profile.
Beyond oil and acid, vinaigrettes benefit from seasoning: fine salt and freshly cracked black pepper are essential. Minced shallot or garlic adds pungency and complexity. Fresh or dried herbs (tarragon, thyme, chives, basil) contribute aromatic notes. A small amount of Dijon mustard serves as both an emulsifier and a flavor enhancer in creamy vinaigrettes. Honey or maple syrup balances acidity and helps emulsification in sweeter dressings.
To make a properly emulsified vinaigrette, combine the acid, emulsifier, and seasonings first, then add the oil very slowly while whisking constantly — this forms a stable temporary emulsion that coats salad leaves evenly. A jar with a tight lid is equally effective: combine all ingredients and shake vigorously. The dressing will separate on standing; simply reshake before each use. A properly emulsified creamy vinaigrette with mustard can stay emulsified in the refrigerator for several days.
Classic French vinaigrette uses a 3:1 oil-to-acid ratio. A brighter, more acidic style uses 2:1. The creamy style uses 3:1 plus an additional portion of emulsifier equal to one-quarter of the total volume (measured in teaspoons).
Classic (3:1): oil = total × 3/4, acid = total × 1/4
Bright (2:1): oil = total × 2/3, acid = total × 1/3
Creamy: same as classic + emulsifier = total × 3/4 tsp
If the vinaigrette tastes too sharp, add oil one teaspoon at a time. If it tastes flat or greasy, add a few drops more acid. Always taste on the actual salad ingredient, not alone — acids taste more pronounced in isolation than when coating a leaf.

The classic French ratio is 3 parts oil to 1 part acid (3:1). This produces a dressing that coats leaves lightly with the oil's richness slightly mellowing the acid's sharpness. It is the foundational ratio of French cuisine and the standard taught in culinary schools worldwide.
Use the brighter 2:1 ratio for heartier, more robust salad ingredients that can stand up to more acidity: kale, radicchio, grain salads, bean salads, roasted vegetable salads, and salads served alongside rich, fatty dishes like fried chicken or pork belly.
Red wine vinegar is the most versatile. White wine and Champagne vinegar are more delicate, ideal for tender lettuces. Apple cider vinegar adds a slight sweetness. Sherry vinegar has a complex, nutty depth. Balsamic vinegar is sweet and thick — best used sparingly or diluted with another vinegar. Fresh lemon juice is bright and aromatic.
Add a small amount of Dijon mustard or honey as an emulsifier. Whisk the acid and emulsifier together first, then add oil very slowly in a thin stream while whisking constantly. An immersion blender produces an extremely stable emulsion. Even with emulsifiers, most vinaigrettes will separate on standing — shake or whisk before use.
A simple oil and vinegar vinaigrette keeps at room temperature for 1–2 weeks as long as it contains no fresh garlic or herbs. Vinaigrettes with fresh garlic should be refrigerated and used within 3 days. Creamy vinaigrettes with mustard or egg keep refrigerated for up to 1 week.
Yes. Dress salads at the last possible moment before serving to prevent wilting. Use just enough vinaigrette to lightly coat the leaves — start with less than you think you need, toss gently, and add more if needed. Overdressed salads are soggy and unpleasant.
A classic French vinaigrette (in French culinary tradition) is simply oil, acid, salt, and pepper. American-style French dressing is an orange-colored, sweet and tangy dressing made with ketchup or tomatoes and various sweeteners — quite different from the French original.
Yes. Fresh citrus juice works beautifully. Lime juice is excellent in Asian-inspired, Mexican, or avocado-based salads. Orange juice (best reduced slightly to concentrate flavor) works well in fruit salads and grain bowls. Use the same oil-to-acid ratios.
Raw garlic directly minced into vinaigrette can be sharp and overpowering. For a milder effect, rub the salad bowl with a cut garlic clove before adding ingredients. Alternatively, steep a crushed clove in the vinaigrette for 30 minutes, then remove it. Roasted garlic blended into the dressing is rich and mellow.
Yes. Simple vinaigrettes scale perfectly and keep well for 1–2 weeks at room temperature (without garlic or herbs) or 1 week refrigerated. Store in a sealed jar and shake vigorously before each use. Make large batches at the beginning of the week for quick, healthy meal assembly throughout.
