Common tattoo sizes in inches and centimetres, what actually fits at each one, and which placements suit them — plus a preview that draws the size on your screen, because almost nobody can picture three inches.
Enter a size and the box below is drawn at that physical size on screen. Hold your arm up next to it.
Close, but treat it as a sense of scale rather than a measurement. Browsers draw physical units like inches and centimetres by assuming 96 CSS pixels to the inch. That assumption holds on most desktop and laptop displays. It can be off on phones and tablets, and it is off by exactly your zoom level if you are not at 100%.
Check it yourself in five seconds. The outline below is drawn at the size of a standard bank or credit card — 85.6 mm by 53.98 mm. Hold a real card against it. If they match, the preview above is accurate on your screen. If the card is bigger or smaller, the preview is wrong in the same direction and by the same proportion.
Before committing to a size, ask your artist to print a stencil at scale and hold it against the skin. Nothing on a screen beats that.
Sizes are quoted by the longest dimension of the piece, which is how most shops price and plan work.
| Size | Inches | Centimetres | What fits | Common placements |
|---|---|---|---|---|
| Tiny | 1 in | 2.5 cm | A single simple symbol — a heart, a cross, a small initial, a tiny outline. | Finger, behind the ear, wrist, ankle, collarbone. |
| Very small | 2 in | 5.1 cm | A small linework design — a moon phase, a wave, a short word, a simple flower. | Wrist, ankle, behind the ear, back of the neck, forearm. |
| Small | 3 in | 7.6 cm | A recognisable subject with some interior detail — a bird, a bee, a compass, a small script phrase. | Forearm, wrist, ankle, shoulder, upper back, hip. |
| Medium | 4 in | 10.2 cm | A single well-developed subject — a rose, an animal portrait head, a small landscape, a short quote in two lines. | Forearm, upper arm, calf, shoulder blade, thigh, chest. |
| Medium to large | 6 in | 15.2 cm | A composed piece with a focal point and background — a framed portrait, a floral arrangement, an animal in a setting. | Forearm, upper arm, thigh, calf, chest, shoulder blade, ribs. |
| Large | 8 in | 20.3 cm | A full panel — a half-sleeve section, a large floral spread, a portrait with a developed background. | Upper back, chest, thigh, full forearm, ribs, hip. |
| Extra large | 12 in | 30.5 cm | A statement piece — a back panel, a full sleeve wrap, a thigh piece running hip to knee. | Back, full sleeve, thigh, chest panel. |
The limit on a small tattoo is not the drawing, it is the skin. Ink spreads a little as it settles and keeps spreading slowly for years, so lines placed close together tend to close up into each other. What follows is what artists commonly report happening, not a measurement.
One weight of line only. Shading, gradients and text smaller than this rarely stay readable as the ink settles.
Two line weights at most. Fine internal detail tends to close up over the years, so open space matters more than content here.
Light shading starts to work. Dense black areas at this size can still spread into each other and lose their edges.
The first size where shading, texture and layered elements generally have room to stay distinct from one another.
Fine linework, smooth gradients and realism all become practical. Most detailed single-session work sits around here.
Detail is no longer the constraint; composition is. Pieces this size are usually designed to the shape of the body part rather than dropped onto it.
Almost always split across multiple sessions. Expect the design to be drawn or stencilled directly on the body so it follows the muscle.
Conventional ranges, not physical limits. Your artist looking at your actual arm will give you a better number than any chart can.
| Placement | Typical size | What to watch for |
|---|---|---|
| Finger tattoos | 0.5–1.5 in / 1–4 cm | The smallest usable canvas on the body, and the fastest to fade. Simple shapes only. |
| Wrist tattoos | 1–3 in / 2.5–7.5 cm | Narrow and curved. Designs that wrap or sit lengthways along the arm work better than wide ones. |
| Behind the ear | 0.5–2 in / 1–5 cm | Very little flat area. Small vertical shapes suit it best. |
| Ankle tattoos | 1–3 in / 2.5–7.5 cm | Bone close to the surface limits both size and how much detail sits flat. |
| Forearm tattoos | 3–8 in / 7.5–20 cm | The most forgiving mid-size canvas: flat, wide enough for detail, and easy to see. |
| Upper arm | 4–8 in / 10–20 cm | Curved, so wide flat designs distort. Pieces that follow the round of the muscle read better. |
| Shoulder tattoos | 4–8 in / 10–20 cm | Flows naturally into a sleeve later, which is worth planning for before the first piece. |
| Chest tattoos | 5–12 in / 12.5–30 cm | Usually designed symmetrically or to one side. The sternum limits how a wide piece sits. |
| Ribs tattoos | 5–10 in / 12.5–25 cm | Long and narrow. Vertical or diagonal compositions suit the shape of the area. |
| Back tattoos | 8–20 in / 20–50 cm | The largest single canvas on the body, and the only one that takes a full panel without wrapping. |
| Hip tattoos | 4–10 in / 10–25 cm | Curves sharply. Designs are normally drawn on the body rather than printed flat. |
| Thigh tattoos | 5–14 in / 12.5–35 cm | Roomy, flat-ish and easy to cover — a common choice for large detailed work. |
| Calf | 4–10 in / 10–25 cm | Naturally tall and narrow, which suits upright subjects. |
| Hand tattoos | 2–4 in / 5–10 cm | Small area, constant wear. Expect touch-ups regardless of the size chosen. |
| Neck tattoos | 2–5 in / 5–12.5 cm | The nape takes more than the throat or the sides, which are tighter and more curved. |
Size and placement together decide how a session feels, too. A small piece somewhere sharp is often easier than a large piece somewhere comfortable, simply because it is over sooner — the tattoo pain chart covers which areas those are.
The usual mistake is picking a size for the artwork and then finding somewhere to put it. Start the other way round: decide the placement, measure the flat area it actually offers, and let the design be drawn to that. A piece that fits the body part reads as intentional; one that was shrunk to fit rarely does.
A small tattoo is fine and a detailed tattoo is fine, but the two together are where things commonly go wrong. Ink spreads slowly for the life of the tattoo, and lines placed close together tend to merge. If a design has to be small, ask your artist to simplify it rather than shrink it.
An upper arm, a hip or a calf is not a flat surface. A design measured across a curve loses width when it settles onto the body, and a wide flat composition distorts. This is why artists draw larger pieces on the skin rather than printing them flat.
Most shops price by time rather than by area, and both scale with size. Anything past roughly six to eight inches with real detail is commonly split across sessions. Ask for the estimate in hours, not just a number, so you know what you are booking.
Two to four inches — roughly 5 to 10 cm — on a flat, forgiving placement like the outer forearm or the shoulder. It is large enough to hold detail without spreading, small enough to finish in one short session, and easy to build on later if you decide you want more.
Three inches is 7.6 cm, roughly the width of a credit card across its short side and a bit more. At that size a recognisable subject with some interior detail works — a bird, a bee, a compass, a short line of script. Use the preview above to see it on screen at actual size.
One to three inches, or about 2.5 to 7.5 cm, is the usual range. The wrist is narrow and curved, so designs that run lengthways along the arm or wrap around it tend to sit better than wide ones.
There is no single cutoff, but the common experience is that below about an inch only simple single-weight shapes hold up. Ink spreads gradually as the tattoo ages, so anything with lines close together — fine internal detail, small lettering, dense shading — tends to close up over the years.
Roughly. Browsers draw physical units by assuming 96 CSS pixels per inch, which is accurate on most desktop and laptop screens but can be off on phones and tablets, and is off by your zoom factor if you are not at 100%. Hold a real bank card against the card outline on this page to check: if it matches, the preview is right on your screen. Before committing, ask your artist for a stencil printed at scale.
One inch is exactly 2.54 cm. So 2 inches is 5.1 cm, 3 inches is 7.6 cm, 4 inches is 10.2 cm and 6 inches is 15.2 cm. Shops in the US and UK usually quote inches; most of Europe, Australia and New Zealand quote centimetres.
Not per square inch, but a larger piece means a longer session, and session length wears people down more than the placement itself does. Large work on a sensitive area is normally split across several appointments for that reason.
