Bas-relief vs high relief: what’s the difference?

If both are “carving on a wall,” why do some reliefs feel quiet and readable while others push into your space?

Bas-relief (low relief) keeps forms shallow with little or no undercutting, so scenes read like drawings that catch light softly.

High relief projects far from the background, often with undercutting and parts nearly free of the slab—closer to sculpture in the round.

Each depth tells stories differently: bas-relief favors long, legible narratives; high relief works like stage presence at thresholds.

The quick visual test: how far does it project?

Let’s make it practical. Stand to the side of a relief and check the silhouette. In bas-relief, figures lift only a little from the stone; edges meet the background all around, and you’ll see minimal undercutting. This keeps shadows thin and lines crisp—your eye reads it almost like a drawing on stone. In high relief, forms protrude half or more of their natural depth and are often undercut, so shadows turn bold and parts can look almost detached. That’s the textbook difference you can trust in a gallery.

Why does this matter? Depth changes how a scene behaves as you move. Low relief supports continuous reading across a wall: your gaze glides left-to-right, register-by-register. High relief, by contrast, grabs you with volume. It performs best at points of arrival—doorways, corners, or focal axes—where a sculpted body can project into your path. Museums and essays make the same point: low relief tends to narrative; high relief tends to presence.

Definition
Bas-relief: shallow carving that barely projects, with little or no undercutting.

Shallow depth powers long stories: Nineveh’s palace walls.

When we say “bas-relief,” think Assyrian palace corridors at Nineveh. Those long gypsum-alabaster panels line up scene after scene—processions, hunts, sieges—at a depth just high enough to catch light and model muscle, but shallow enough to keep the wall readable at walking speed. In the Lion Hunt of Ashurbanipal, the king drives chariots, lions charge, and attendants react, all spread across registers and sequences you can follow as you move. Low relief is the reason it reads like a film strip.

Zoom into two moments. First, the famous dying lion: the body buckles, veins bulge, blood jets—yet the carving stays shallow so the anatomy reads cleanly from meters away. Second, a quieter panel of grooms leading horses to prepare the hunt: figures align, ground lines are firm, and the whole scene behaves like disciplined drawing in stone. Both use low relief to prioritize legibility over thrust. If you’re building your own comparison set, pair them with our deep dives.

Scholars have long noted how this shallow depth serves state narrative. Irene Winter’s classic studies show how Neo-Assyrian reliefs structure time and authority—register by register, episode by episode—so that viewers effectively “read” royal action across space. Low relief is the grammar that makes that reading possible.

High relief makes thresholds act on you: Khorsabad’s lamassu.

Now meet high relief at the door. At Khorsabad (Dur-Šarrukīn), the colossal lamassu—human-headed, winged bulls—project strongly from the stone block. Heads, chests, and wings push out; legs are deeply modeled; undercut beards and feathers throw heavy shadow. From the front, the guardian seems to stand still. As you pass, it seems to stride. That famous “five-leg” solution works because the carving is volumetric enough for two convincing views. High relief, placed at a threshold, becomes choreography.

This is relief behaving like architecture. The figure isn’t just on the wall; it helps make the doorway—controlling pace, framing sightlines, and broadcasting power at the exact spot your body slows down. Excavation reports and museum guides put these bulls right where they matter most: flanking major palace gates so that scale and projection work together. If you want a single object that explains high relief’s job in space, it’s the lamassu.

Myth vs Fact
Myth: High relief is just “more detailed” carving.
Fact: It’s deeper projection with undercutting, used strategically for presence at focal points.

Tools, materials, and the “why” behind depth choices.

Technique tracks with purpose. Assyrian palace panels are carved in gypsum alabaster—a soft stone that takes crisp line at shallow depth, perfect for long narrative walls set into mud-brick architecture. The shallow lift keeps slabs lighter, surfaces more uniform, and sequences easy to read under changing light. Manuals and museum publications note how panels were fixed along corridors, their low relief designed for clarity over drama.

High relief demands harder edges and undercut shadows, so you’ll often see it where impact beats reportage: at entries, on façade elements, or in sculptural ensembles that perform across a room. The optical payoff is different: strong shadows at oblique angles, volumetric presence up close, and an almost “in-the-round” feel head-on. That’s why sources define high relief by projection (often half or more of the form) and by undercutting, not simply by the fineness of detail.

Reading tip. When you’re unsure, don’t count millimeters; look for behavior. If a relief reads like a drawing you can walk along, it’s probably bas-relief. If it pushes into your path and works from multiple angles, it’s probably high relief. Then ask the helpful follow-up: what did the patron need—story or presence?

Conclusion: Two depths, two kinds of power.

Bas-relief and high relief aren’t rivals; they’re tools. Low relief carries long stories—perfect for palace corridors where a ruler wants us to read campaigns, hunts, and building projects in sequence. High relief delivers immediate presence—perfect for gates and thresholds that choreograph awe. Once you see the depth logic, Assyrian art becomes easier to read: the Nineveh hunts teach narrative; the Khorsabad guardians stage entry.
