Great White Shark Tooth Size Guide
How big do great white shark teeth get, how are they measured, and how does size interact with the other variables that drive value? A practical guide for collectors deciding which size band fits their collection.
Size is the most-asked variable in the great white tooth market and the one most commonly misunderstood. Most buyers picture a single 'shark tooth size,' but adult dentition varies meaningfully by position in the jaw, by upper-vs-lower placement, and by the individual animal. This guide explains how teeth are measured, what the standard size bands are, how the bands map to price tiers, and how size compares between modern great whites and the fossil species in the broader catalog.
Slant Height — The Standard Measurement
Size in shark tooth collecting is reported as slant height: the longest straight-line distance from the deepest point of the root to the tip of the tooth. Not perpendicular height, not chord length, not curve. Slant height is the convention used by collectors, dealers, and museums, and it is what every credible listing should quote.
To measure a tooth at home, lay it flat on a hard surface and use a calibrated digital caliper or a steel machinist ruler. Place one end of the measuring tool at the deepest visible point of the root, and read the distance to the tip. Repeat from the same starting point and confirm. Most teeth measure consistently to within 0.05 inches across attempts.
Adult Great White Size Bands
Most adult anterior great white teeth fall between 1.5 and 2.5 inches in slant height. The bands matter because the supply distribution is uneven — there are many more teeth in the lower bands than in the upper — and the pricing follows.
| Slant height | What it represents | Typical grade-A modern price |
|---|---|---|
| Under 1.5" | Lateral or sub-adult anterior. Common. | $75 – $250 |
| 1.5" – 2.0" | Adult anterior, mid-tier supply. | $200 – $500 |
| 2.0" – 2.5" | Strong adult anterior. Increasingly scarce. | $400 – $1,000 |
| Over 2.5" | Exceptional. Rarely changes hands. | $900 – $1,250+ |
Pre-ban premium rides on top of these bands. A documented pre-ban tooth in the 2.0–2.5" band routinely clears the upper end of the documented modern range. Above 2.5" with documented pre-ban provenance, pieces enter four-figure pricing and inquiry-only sales become more common.
Size by Position in the Jaw
A single great white carries teeth across multiple positions, and the positions vary in size. The first three to five teeth on either side of the midline — the anteriors — are the largest in the working row. Lateral teeth that extend back along the curve of the jaw are progressively smaller. Posterior teeth at the back of the jaw are smaller still, often under one inch. Symphyseal teeth at the midline itself are the smallest, typically well under an inch.
This means a single animal with two-inch anteriors will produce one-and-a-half-inch laterals and sub-one-inch posteriors. The size of a tooth alone does not tell you the size of the animal it came from. A 1.5-inch lateral and a 1.5-inch anterior may come from animals of very different sizes. Position, recorded on the listing, is the variable that lets you reason about the source animal correctly.

Upper vs Lower
Width-to-height ratio differs between upper and lower teeth. An upper anterior is broad — the width is close to or exceeds the slant height. A lower anterior is narrower than tall, with a more daggerlike profile. Both come from the same animal at the same age and represent the same biological investment, but they read differently in the catalog and on display.
If you are evaluating a listing and the position has not been specified, the width-to-height ratio is the fastest tell. A tooth that is roughly as wide as it is tall is almost certainly an upper anterior. A tooth that is noticeably taller than wide is a lower anterior or a lateral.
How Size Compares Across Species
Modern great white anteriors top out around 2.5 inches in slant height for typical adult animals, with exceptional pieces reaching 3 inches. The fossil category includes much larger species. Otodus megalodon — the largest predatory shark in the geological record — produces anterior teeth routinely above 4 inches, with exceptional specimens approaching 7 inches. Mako ancestors and smaller Otodus species fall between the modern great white range and the upper Megalodon range.
| Species | Typical anterior size | Exceptional anterior size |
|---|---|---|
| Modern great white (Carcharodon carcharias) | 1.75–2.5" | ~3" |
| Modern shortfin mako (Isurus oxyrinchus) | 1.0–1.75" | ~2" |
| Modern tiger (Galeocerdo cuvier) | 0.75–1.25" | ~1.5" |
| Otodus megalodon (fossil) | 3.5–5" | ~7" |
| Otodus obliquus / auriculatus (fossil) | 2–3.5" | ~4.5" |
| Mako ancestor (Isurus / Cosmopolitodus hastalis) | 2–3" | ~4" |
Comparison sets often pair a modern great white anterior with a Megalodon at three or four inches. Same broad triangular shape, dramatically different scale, dramatically different patina. Many collectors build their first multi-piece display around exactly that pair.
Display Considerations by Size
Smaller teeth (under 1.5 inches) display well on small acrylic stands or in study sets where multiple pieces share an archival card. Mid-range teeth (1.5–2.5 inches) work best individually on slightly larger stands or framed in shadow boxes. Larger pieces (over 2.5 inches for great whites, over 4 inches for Megalodons) need pedestal mounts or glass-fronted display cases that protect the specimen and give it visual presence.
The width-to-height ratio also affects display planning. Broad upper anteriors photograph well from straight on; narrower lower anteriors photograph better at a slight angle. Vertical mounting on a stand is more stable for narrow teeth; broader teeth are sometimes laid flat on a velvet card.

Size and Value Are Not the Same
Size is one of four variables that drive value. The other three — era, condition, and documentation — can compound or override size. A 2.4-inch grade-C tooth with a broken tip and a chipped root usually prices below a 2.0-inch grade-A tooth with intact serrations and a complete root, because condition compounds with size and a damaged large tooth still reads as damaged. A documented pre-ban two-inch tooth typically prices above a documented modern two-and-a-half-inch tooth, because the era premium overrides the size advantage.
Knowing the size band tells you where in the price ladder you are looking, but it does not finish the answer. The full framework is on the What Makes a Great White Shark Tooth Valuable? page.

Frequently Asked Questions
How big do great white shark teeth get?
Most adult anterior teeth fall between 1.5 and 2.5 inches in slant height. Specimens above 2.5 inches are exceptional and rarely change hands. Above 3 inches is essentially a museum-grade size for the species.
How big does a Megalodon tooth get?
Otodus megalodon anteriors routinely run 3.5 to 5 inches; exceptional specimens approach 7 inches. Megalodon teeth are larger than any modern great white tooth.
What size great white tooth should I buy first?
For most collectors, a 1.5–2.0 inch grade-A tooth in the $200–$500 range is the strongest first piece. The size is iconic, the price tier is accessible, and the band has the deepest supply at any given moment.
How do I know if a tooth is upper or lower?
Compare width to slant height. Upper anteriors are broad — width approaches or exceeds height. Lower anteriors are narrower than tall, with a more daggerlike profile.
Are larger teeth always more valuable?
Within the same era and condition band, yes. But size does not override condition or era. A 2.4-inch grade-C tooth with a broken tip can price below a 2.0-inch grade-A tooth, and a documented modern 2.5-inch tooth can price below a documented pre-ban 2.0-inch tooth.
