A pint glass is a drinking vessel made to hold either a British ("imperial") pint of 20 imperial fluid ounces (568 mL) or an American pint of 16 US fluid ounces (473 mL). These glasses are used predominantly to serve beer.
Current shapes 
The common shapes of pint glass are:
- Conical (or sleevers) glasses are shaped, as the name suggests, as an inverted truncated cone around 6 inches (15 cm) tall and tapering by about 1 inch (25 mm) in diameter over its height.
- The nonic, a variation on the conical design, where the glass bulges out a couple of inches from the top; this is partly for improved grip, partly to prevent the glasses from sticking together when stacked, and partly to give strength and stop the rim from becoming chipped or "nicked". The term "nonic" derives from "no nick".
- Jug glasses, or "dimple mugs", are shaped more like a large mug with a handle. They are moulded with a grid pattern of thickened glass on the outside, somewhat resembling the segmentation of a Mills bomb. The dimples prevent the glass slipping out of the fingers in a washing-up bowl, and the design of the glass emphasises strength, also to withstand frequent manual washing. These design features became less important when manual washing was superseded by machine washing from the 1960s onwards. Dimpled glasses are now rarer than the other types and are regarded as more traditional. This sort of glass is also known as a "Handle" or "Jug" due to the handle on the glass. They are popular with drinkers who prefer a traditional beer experience.
- tulip is a more modern glass having a taller shape, usually flaring out towards the top; these designs are more commonly associated with continental lagers or promotional campaigns by breweries, and are frequently etched or marked with the beer's label.
Older styles 
Older styles include:
- Decorative Toby jugs, although these would not have been for everyday use. Mid 1700s onwards.
- Pewter tankards. 1500s to 1900s
- Ceramic tankards with strap handles. Late 1800s to early 1900s.
- 10-sided glass tankards. 1920s and 1930s.
United Kingdom law 
In the United Kingdom, draught beer must be sold in Imperial measure (see Pint#Effects of metrication). United Kingdom law requires certain steps be taken to ensure that a pint of beer is indeed a pint. Though this can be achieved using so-called "metered dispense" (calibrated pumps), the more common solution is to use certified one-pint glasses. Until recently these had a crown stamp and number etched upon them indicating that the certification had been done by an agency of the Crown. In Ireland a harp was used to denote official certification.
Under the EU Measuring Instruments Directive (Directive 2004/22/EC), the certification of measuring instruments and devices used in trade (including beer mugs, weighbridges, petrol pumps and the like) can be done by third parties anywhere within the EU with governments taking "only the legislative and enforcement (market surveillance) functions" and "ensuring that the system of third party assessment ... has sufficient technical competence and independence" (or, in simple language, calibration services were privatised). Glasses that have been certified by authorised firms anywhere within the EU have the letters CE etched on with the certifying agency's identification number. Conservatives campaigning to have dual markings of crown and CE were informed by EU Commissioner Günter Verheugen that "a Crown stamp look-alike could naturally be affixed to the glass, as long as it is done in such a way that it is not confused with the CE marking".
Selling beer in unmeasured glasses without using some other form of calibrated measure is illegal. Half-pint and one-third pint glasses are also available, and are subject to the same laws.
Despite this emphasis on accurately measured glasses, there is a practice of defining a pint of beer and lager as only 95 per cent liquid. It is common for drinkers to be served less than a full 568 ml pint of liquid — either because too much of the glass is taken up by a foamy "head", or simply because the customer has been sold a short measure. This allows publicans to sell more beer than the stated capacity of the cask or keg and hence save money. This practice may have consciously increased since the removal of a duty allowance on ullage (wastage). To counter this the British Beer and Pub Association have issued guidelines for bar staff to respect a customer who asks for a 'top up' to a full 568 ml pint.
For those wishing to avoid this practice while still serving beer with a large head, "lined" or "oversized" glasses are available. These have a line near the top (usually labelled "pint to line") to which the beer should be poured, with the head forming above it. In the past a number of breweries supplied these glasses to their pubs; this is now rarely the case and lined glasses are found mostly at enthusiasts' events such as beer festivals, serious cask ale pubs, and breweries' own bars. The use of lined 568 ml pint glasses in pubs is advocated by the Campaign for Real Ale. In Australia, however, this style of glass is universal, with the exception of South Australia, which sells pints in a 425ml glass.
Other countries 
In the United States, a pint is 16 fluid ounces (473 mL). Recently (as of 2008), some restaurants have replaced 16-ounce pint glasses (473 mL) with 14 ouncers (415 mL) to which customers have objected.
The Republic of Ireland also uses 570 mL 1 pint glasses, where legal metrology marks are used to show that a glass has passed inspection by the National Standards Authority of Ireland, a state-run body who enforce a number of standard rulings. Starting in 2006, the NSAI "pint" mark, a circle featuring two wavy lines, between which "PINT" is written, with a year mark (last two digits), and a three digit batch code either side; has begun to be phased out with a European standard "PINT"/CE logo stamp. Smaller Pint glasses have been used in pubs and nightclubs though.
Nucleated pint glasses 
It is increasingly common to find pint glasses which contain markings on the base; very often these glasses are branded to one particular beer. The markings themselves are formed from small pits which aid in nucleation, allowing the gas within it to be released more easily, thus preserving the head. Without the aid of these pits a regular pint glass will keep a head for only 3 or 4 minutes before appearing 'flat'. The markings come in a variety of styles ranging from a simple circular or square hatched pattern to more complicated branding messages.
Pint glass collecting 
Pint glass collecting is an increasingly popular way for individuals to commemorate their visits to popular tourist destinations, most notably to microbreweries or sports arenas. These destinations often sell pint glasses adorned with their logos, which are either silkscreened or engraved on the side of the glass. Brewery enthusiasts may travel thousands of miles to see where their favorite beer is made or to sample new local and fresh beers, and collectors often display their collections (which sometimes total in the hundreds) in display cases or on shelves.
Beer festivals frequently have commemorative pint glasses made specially for the event.
