From 15ml bar jiggers to 75ml multi-mark single cups — this guide covers every standard cocktail jigger size, oz-to-ml conversions, regional market standards, and how to choose the right size for your bar or product line.
What Is a Standard Jigger Size?
There is no single universal “standard” jigger size. The right size depends on your market region, the cocktail recipes you’re working with, and whether you’re using a single or double jigger. That said, the most widely used jigger size globally is the 30ml / 60ml (1oz / 2oz) double jigger — it covers the two most common pour sizes in classic and contemporary cocktail recipes.
Jigger sizes are typically expressed in two measurement systems:
- Millilitres (ml) — standard in the UK, Europe, Australia, and most of Asia
- Fluid ounces (oz) — standard in the United States
Understanding both systems is essential for sourcing jiggers for international markets.
Jigger Size Chart: oz to ml Conversion
The table below covers the most common jigger volumes used in bars worldwide. Use this as a reference when specifying jigger sizes for sourcing, labeling, or market compliance.
| ml | oz (approx.) | Common use |
|---|---|---|
| 15ml | ½ oz | Modifier / accent pours, liqueurs |
| 20ml | ⅔ oz | UK single spirit measure |
| 25ml | ¾ oz | UK single spirit measure (standard) |
| 30ml | 1 oz | US standard single / most common measure |
| 40ml | 1⅓ oz | European single spirit measure |
| 45ml | 1½ oz | US standard jigger / 1.5 oz pour |
| 50ml | 1⅔ oz | European double spirit measure |
| 60ml | 2 oz | US standard double / large pour |
| 75ml | 2½ oz | Large single pour / multi-ingredient base |
Standard Jigger Size Combinations (Double Jiggers)
Double jiggers — the hourglass-shaped two-sided measuring tool — are the most widely used jigger format in professional bars. Each side measures a different volume, giving the bartender two precise measures in one tool.
15ml / 30ml
The smallest double jigger configuration. Primarily used in markets where smaller single spirit measures are legally mandated — particularly the UK (where 25ml is the legal single and some bars use 15ml for liqueurs) and parts of Europe. Also useful for precision modifier pours such as bitters-heavy cocktails and layered shots.
Best markets: UK, parts of Europe, specialty cocktail bars working with small-volume modifiers.
20ml / 40ml
A European-standard double jigger reflecting the most common spirit measure sizes in continental Europe — 20ml as a small pour and 40ml as the standard single in many European countries. Less commonly seen in the US or Australian market.
Best markets: Continental Europe, particularly Germany, France, and Eastern Europe.
25ml / 50ml
One of the most important jigger sizes for the UK and Australian markets. In the UK, 25ml is the legal single spirit measure and 50ml is the double. In Australia, 30ml is standard but 25ml/50ml is widely used. This combination is a high-priority SKU for any buyer sourcing for these markets.
Best markets: UK, Ireland, Australia, New Zealand, South Africa.
30ml / 60ml
The global all-rounder — equivalent to the US 1oz / 2oz double jigger, and the most universally stocked size across North America, Asia, and increasingly in international hotel and bar programs. If you stock only one double jigger size, this is it.
Best markets: United States, Canada, Asia, international hotel programs, global bar supply.
30ml / 45ml
A popular alternative to the 30ml/60ml for bars that frequently pour 1oz and 1.5oz measures — common in classic cocktail recipes such as the Margarita, Daiquiri, and Whiskey Sour, where a 1.5oz spirit pour and 1oz modifier are standard. The 45ml side is also the traditional US “jigger” measure.
Best markets: United States, Canada, craft cocktail bars worldwide.
Double Jiggers with Internal Measurement Markings
Beyond the two fixed volumes of a standard double jigger, several configurations are available with internal measurement markings etched inside one or both cones. These markings allow bartenders to pour precise intermediate volumes — not just the two fixed capacities — making them significantly more versatile for complex recipes.
The following double jigger sizes are available with internal markings:
25ml / 50ml with internal markings Internal marks allow precise pours at 10ml, 15ml, 20ml, 25ml, 30ml, 40ml, and 50ml — covering virtually every common recipe measure within the range. Ideal for craft cocktail bars working with UK or Australian measures.
30ml / 45ml with internal markings Internal marks at 10ml, 15ml, 20ml, 25ml, 30ml, and 45ml. The most versatile combination for US-focused craft cocktail bars — covers ¼ oz, ½ oz, ¾ oz, 1oz, and 1.5oz in a single tool.
30ml / 60ml with internal markings Internal marks at 10ml, 15ml, 20ml, 25ml, 30ml, 40ml, 50ml, and 60ml. The most comprehensive double jigger available — covers the full range of common recipe measures from a small modifier to a double pour. The best choice for bars that need maximum measurement flexibility without switching tools.
For buyers: The internal-marking versions command a premium over standard double jiggers and are increasingly preferred in craft cocktail and premium bar supply channels. They are also a strong retail product — the visible etched markings communicate quality and precision at point of purchase.
Single Jigger with Internal Markings: Up to 75ml
For bars that prefer a single-cone jigger, the 75ml single jigger with internal markings offers the widest measurement range available in one tool. With etched markings at 15 / 20 / 30 / 45 / 60 / 75ml, it covers every common pour size from a small modifier to a large base spirit pour — without needing to flip the tool or switch between jiggers.
Internal markings:
| Mark | oz equivalent | Common use |
|---|---|---|
| 15ml | ½ oz | Modifier / liqueur |
| 20ml | ⅔ oz | UK small measure |
| 30ml | 1 oz | Standard single |
| 45ml | 1½ oz | Standard jigger measure |
| 60ml | 2 oz | Double pour |
| 75ml | 2½ oz | Large base spirit / batching |
Advantages over a double jigger:
- No flipping required — one orientation for all measures
- Maximum capacity (75ml) handles large pours and some small batch cocktails
- Internal marks are clearly visible with one hand holding the jigger upright
- Particularly intuitive for bartenders transitioning from graduated cylinders or measuring cups
Best for: Craft cocktail bars, bartenders who prefer single-cone tools, training environments where simplicity aids learning, and retail buyers looking for a distinctive premium product.
Jigger Sizes by Market / Region
Sourcing jiggers for international markets requires understanding the spirit measure standards in each region — both for compliance and for product-market fit.
United States
The US standard is built around the 1oz (30ml) and 1.5oz (45ml) measures. The classic American “jigger” is 1.5oz on the large side and 1oz (or 0.75oz) on the small side. The 30ml/60ml and 30ml/45ml double jiggers are the dominant SKUs.
Recommended sizes for US market: 30ml/60ml, 30ml/45ml, 75ml single with internal markings.
UK & Ireland
The UK has legally mandated spirit measures of 25ml (single) and 50ml (double) for licensed premises. Any bar tool set sold for professional use in the UK should include a 25ml/50ml jigger. The 15ml/30ml is also useful for modifier pours.
Recommended sizes for UK market: 25ml/50ml (with internal markings), 15ml/30ml.
Europe (Continental)
Spirit measures vary by country but the most common professional standard across continental Europe is 20ml (small) and 40ml (standard single). The 20ml/40ml double jigger is the core SKU for this market. The 25ml/50ml also sells well in Western Europe.
Recommended sizes for European market: 20ml/40ml, 25ml/50ml.
Australia & New Zealand
Australia uses 30ml as the standard single and 60ml as the double, aligning closely with the US system. However the 25ml/50ml is also widely stocked. Dual oz/ml marking on jiggers is common and preferred by many Australian bar programs.
Recommended sizes for Australian market: 30ml/60ml, 25ml/50ml.
Asia & International Hotel Programs
Asian markets and international hotel bar programs typically follow either US (oz) or metric (ml) systems depending on brand origin. The 30ml/60ml is the safest all-market default. Japanese craft cocktail programs increasingly use multi-mark single jiggers for precision.
Recommended sizes for Asia / international: 30ml/60ml, 75ml single with internal markings.
Which Jigger Size Is Right for Your Bar?
For home bars and beginners: The 30ml/60ml double jigger is the best starting point — it covers the most common recipe measures and is the most universally understood size. If you want more precision, the 30ml/60ml with internal markings eliminates the need to estimate intermediate volumes.
For professional cocktail bars (US): The 30ml/45ml with internal markings is the most versatile single tool for classic and contemporary cocktail programs. Pair with a 30ml/60ml for recipes requiring a full 2oz pour.
For professional bars (UK/Europe): The 25ml/50ml with internal markings is the essential SKU. Supplement with a 15ml/30ml for modifier-heavy menus.
For craft cocktail and precision-focused programs: The 75ml single jigger with internal markings offers the widest measurement range in one tool and is increasingly popular in bartenders who prioritize workflow efficiency and precision over the traditional double jigger flip.
Which Jigger Sizes to Stock (For Buyers & Distributors)
For bar supply buyers, distributors, and brand owners, jigger size selection is a market-fit decision. Here is a practical stocking guide based on target market:
| Target market | Must-stock sizes | Optional additions |
|---|---|---|
| US retail / e-commerce | 30ml/60ml, 30ml/45ml | 30ml/60ml with markings, 75ml single |
| UK / Ireland trade | 25ml/50ml with markings | 15ml/30ml |
| European trade | 20ml/40ml, 25ml/50ml | 25ml/50ml with markings |
| Australian trade | 30ml/60ml, 25ml/50ml | 30ml/45ml with markings |
| Global hotel programs | 30ml/60ml | 75ml single with markings |
| Craft cocktail supply | 30ml/45ml with markings, 30ml/60ml with markings | 75ml single with markings |
| Gift / retail sets | 30ml/60ml | 30ml/45ml |
Dual oz/ml marking is strongly recommended for any jigger sold into international channels or multi-market retail programs — it eliminates the need to stock separate oz and ml SKUs and broadens the addressable market for each product.
Frequently Asked Questions
What is the standard jigger size?
The most universally used jigger size is the 30ml/60ml (1oz/2oz) double jigger. It is the default size in the US market and is widely stocked in Asia, Australia, and international hotel programs. For the UK and Europe, 25ml/50ml is the regulated standard.
What does 1oz mean on a jigger?
1oz (fluid ounce) is approximately 30ml. On a double jigger marked 1oz/2oz, the small side measures 30ml and the large side measures 60ml. Most professional jiggers are available with dual oz/ml markings for international use.
What is the difference between a jigger and a shot glass?
A jigger is a precision measuring tool with two sides (or multiple internal markings) designed for accurate cocktail preparation. A shot glass is a serving vessel. While a shot glass can be used to estimate volumes, it lacks the precision markings and consistent calibration of a proper jigger.
What jigger size is best for home use?
For home bars, a 30ml/60ml double jigger covers the majority of classic cocktail recipes. If you want more versatility without carrying multiple tools, the 30ml/60ml with internal markings or the 75ml single jigger with internal markings at 15/20/30/45/60/75ml are excellent choices.
Can jigger sizes be customized for different markets?
Yes. Jiggers can be manufactured with oz, ml, or dual oz/ml markings to suit US, European, UK, Australian, and other markets. Internal marking configurations can also be specified for OEM orders to match market-specific pour standards.
What is the difference between a jigger with internal markings and a standard double jigger?
A standard double jigger has two fixed volumes — one per side — with no intermediate marks. A jigger with internal markings has additional etched lines inside the cone(s), allowing precise pours at multiple volumes between the two fixed capacities. This significantly increases versatility, particularly for craft cocktail programs with complex recipes.
