Short answer
The familiar US kitchen distinction is fruit form: jelly is made from juice, jam usually from crushed or chopped fruit, and preserves usually retain larger pieces or whole fruit. The legal line is less tidy. Federal standards have a separate fruit-jelly category but place fruit preserves and jams together under one standard. 1 2
All three are fruit spreads. Everyday US usage distinguishes their typical fruit form, while federal standards group jam and preserves together and describe fruit jelly separately.

What each thing is
Jam. Jam is a fruit spread made by cooking crushed or chopped fruit with sugar, resulting in a thick, textured mixture containing small pieces or pulp of the original fruit. 1 2
Jelly. Jelly is a clear or translucent fruit spread produced by cooking fruit juice with sugar, yielding a smooth, gelled product without visible pieces of fruit or pulp. 1 2
Preserves. Preserves are fruit spreads in which whole fruit or large pieces are suspended in a syrup or gel, offering a chunkier texture and more intact fruit than jams or jellies. 1 2
Key differences
Fruit form is the most useful culinary cue: juice gives jelly a smooth gel; crushed fruit commonly makes jam; larger intact pieces commonly make preserves. Federal standards separately describe fruit jelly and group fruit preserves with jams, so the jam/preserves distinction should be presented as a usage convention rather than a rigid legal division. 1 2
How to tell them apart
Look at both the ingredient description and the spread itself. Clear, smooth fruit gel suggests jelly; fruit pulp suggests jam; recognizable larger pieces suggest preserves. Texture can overlap, and a front label alone cannot establish a separate legal boundary between jam and preserves under the shared federal standard. 1 2
Where they overlap
There is overlap in texture and appearance, especially with homemade or artisanal products. Some jams may be nearly as smooth as jelly, and some preserves may have a consistency similar to jam, depending on the fruit and preparation method. 1
Edge cases
A finely crushed preserve may look much like jam, while a jam made from seeded berries can be visibly chunky. Reduced-sugar fruit spreads may follow different formulations. These examples show why fruit texture is a helpful shopping cue but not a universal naming test. 1 2
Why the distinction exists
The everyday names describe how fruit is prepared and what texture a cook expects. US federal rules address composition for standardized fruit jelly and for fruit preserves and jams as a combined category. That regulatory grouping explains why a separate legal fruit-size cutoff between jam and preserves would overstate the source. 1 2
Common misconceptions
A common oversimplification is that US law requires jam and preserves to have sharply different fruit-piece sizes. In ordinary cooking, preserves tend to keep larger pieces and jam tends to use crushed fruit. But the federal standard groups their names, while fruit jelly has its own standard. 1 2
Examples
At a US grocery store, a shopper might select strawberry jam for a sandwich (expecting a spread with fruit bits), grape jelly for a clear, smooth topping, and peach preserves for spooning over biscuits, with visible chunks of peach in syrup. 1
