Enlarge and magnify both deliver a bigger image of something, but only one changes the thing. To enlarge is to make it actually bigger — an enlarged print has more paper, an enlarged room more floor. To magnify is to make it look bigger while it stays the same — the lens's work. Blow a photo up to poster size and you have enlarged it; hold a glass over it and you have only magnified it.
The pair splits reality from optics. Enlarge, from Old French enlargier, changes dimensions: the enlarged thing measures more afterwards, which is why it needs an outside hand and real material — more paper, more brick. Magnify, from Latin magnus, changes only the view: the object under the lens keeps every one of its millimetres. Photography keeps both on staff and keeps them straight: the darkroom enlarges (prints at greater size); the loupe magnifies (shows the same print larger to the eye).
enlarge
To enlarge is to make something bigger — most often a concrete thing you can point to: a photograph, a room, a diagram. It comes from Old French enlargier, 'to make large', and it keeps that sense of a size increased deliberately, usually by an outside hand rather than by growth from within. That is the quiet line between it and expand: a business expands of its own momentum, but you enlarge a print. In the phrase 'enlarge on', it means to say more about a point.
magnify
To magnify is to make something look bigger without changing the thing itself — the work a lens does, enlarging the appearance of what is under it. From Latin magnificare, 'to make great' (the magnus family that also gives magnitude and magnate), it carries a second, figurative sense: to magnify a risk or a fear is to make it loom larger than it really is, often unhelpfully. In that mood it shades toward amplify and exaggerate. A magnifying glass magnifies print; anxiety magnifies problems.

| Meaning | make actually bigger | make look bigger |
| Afterwards | measures more | measures the same |
| Needs | an outside hand, real material | a lens (or a fearful imagination) |

| Figurative | enlarge on a point = say more | magnify a risk = exaggerate it |
| Noun | an enlargement (a thing) | magnification (a degree: ×8) |
The handle and the lens. The photo dragged out by its corner handle is enlarged: there is simply more of it now, and a ruler would agree. The speck under the glass is magnified: huge to the eye, unchanged on the table, a dot again when the lens moves on. So ask the ruler's opinion. If measurements moved, enlarge; if only the view did, magnify. Fears, usefully, can only be magnified — no ruler has ever caught one growing.

The devices keep the grammar honest — and a projector, oddly, does both jobs in one throw: the image on the wall is genuinely larger (light rebuilt it there), though we casually say the slide is magnified. Where precision matters — microscopy, mapping, print — the split is strict: enlargement produces a bigger object (a print, a copy); magnification is a ratio (×40) describing appearance. Enlarge's other border, with expand, is mapped on its own page on this site.
Description and process tasks reward the reality line: 'the image is magnified ×400' (a viewing ratio) versus 'the diagram has been enlarged for clarity' (a bigger physical copy). In figurative territory the words accuse differently — an enlarged claim would be a bigger claim; a magnified claim is an inflated view of the same claim. When growth of scope is meant rather than size, expand takes over; that boundary lives on the enlarge-vs-expand page.
