Chiminea Sizes: Dimensions, Weight and How Much Space One Needs
Typical heights, belly widths and mouth openings for clay, cast iron and steel chimineas, what size of wood each takes, how far one should stand from buildings and how to lay out seating around its one-sided heat.
A medium chiminea stands about 36-45 in (91-114 cm) tall with a belly 20-24 in (51-61 cm) across and a mouth about 12-15 in (30-38 cm) wide. Small clay models start around 28-30 in; large cast iron and steel models reach 55-70 in (140-178 cm) with the chimney. Under the International Fire Code, a chiminea is a portable outdoor fireplace and needs 15 ft (4.6 m) from structures.

Chiminea dimensions by size
A chiminea is a free-standing outdoor fireplace with a round belly, a front mouth and a chimney. Retailers label them small, medium, large and extra large, but the labels vary, so compare by overall height, belly width and mouth size.
| Size | Overall height | Belly width | Mouth opening (W × H) | Log length |
|---|---|---|---|---|
| Small | 28-35 in (71-89 cm) | 14-18 in (36-46 cm) | 9-11 × 8-10 in | Up to 8-10 in |
| Medium | 36-45 in (91-114 cm) | 20-24 in (51-61 cm) | 12-15 × 10-13 in | Up to 10-12 in |
| Large | 46-55 in (117-140 cm) | 24-28 in (61-71 cm) | 14-17 × 12-15 in | Up to 12-14 in |
| Extra large / cast iron | 55-70 in (140-178 cm) | 26-32 in (66-81 cm) | 15-18 × 13-17 in | Up to 14-16 in |
Overall height includes the stand, which adds 6-12 in on most clay models. The log lengths assume wood laid inside the bowl without poking out of the mouth; a burning log that sticks out drops embers on the ground in front.
Clay, cast iron and steel chimineas compared
| Material | Common heights | Weight | Notes |
|---|---|---|---|
| Clay (terracotta) | 28-55 in | About 30-100 lb (14-45 kg) | Narrow neck, smaller mouth; cracks if fired hard when cold or wet |
| Cast iron | 45-70 in | About 70-150 lb (32-68 kg) | Wide bowl and mouth, more heat; rusts without paint or cover |
| Steel (sheet or powder-coated) | 40-70 in | About 25-60 lb (11-27 kg) | Lightest; thinner walls get hotter on the outside |
| Cast aluminum | 40-60 in | About 30-60 lb (14-27 kg) | Does not rust; often decorative |
Clay chimineas hold heat less well than they look: the thick walls stay cool outside, so most of the warmth comes out of the mouth. Metal models radiate heat from the whole bowl as well, which warms a wider area but means children and pets need to stay further back.
How much space a chiminea needs
A chiminea heats mainly in front of the mouth, in an arc of about 180 degrees. Seating goes in that arc, not all the way round as with a fire pit.
- Footprint: the stand or base, usually 16-30 in (41-76 cm) across.
- Hearth zone: a non-combustible area extending at least 2-3 ft (61-91 cm) in front of the mouth. For comparison, the residential code requires an indoor fireplace hearth to extend at least 16 in in front of an opening under 6 sq ft (IRC R1001.10); an outdoor chiminea on gravel or pavers deserves more.
- Seating arc: chair fronts about 3-5 ft (0.9-1.5 m) from the mouth. Three or four chairs fit in the arc; a fifth ends up behind the stack where there is little heat.
- Overall zone: plan roughly 10 × 8 ft (3.0 × 2.4 m) for a medium chiminea with three chairs, with the long side across the front.
Face the mouth away from the prevailing wind so smoke and sparks go up the chimney instead of out of the front. For seating that surrounds the fire, compare the circles in the fire pit size guide; for chair dimensions, see outdoor furniture sizes.
Clearance from buildings and overhead
The International Fire Code (IFC) classes a chiminea as a portable outdoor fireplace: a portable, solid-fuel-burning outdoor fireplace of steel, clay or similar material, which may have a small hearth opening and a short chimney. Section 307.4.3 says it must be used per the manufacturer's instructions and not within 15 ft (4.6 m) of a structure or combustible material. That is 10 ft less than the 25 ft the IFC sets for an open recreational fire.
- Overhead: open sky above the stack. Sparks leave the chimney 2.5-6 ft above the ground, depending on the model, so a pergola, umbrella or branch above it is a fire risk.
- Decks: use only if the manufacturer allows it, on a non-combustible pad that covers the footprint plus the hearth zone in front.
- Local rules: many cities amend the IFC distance, require spark screens, or ban wood burning on poor air-quality days. Apartment leases often ban chimineas outright.
A chiminea is not a stove. Never use one in a garage, conservatory, tent or enclosed porch: it produces carbon monoxide and has no flue system to remove it.
Setting up a clay chiminea
- Add a sand layer. Fill the bowl with 2-4 in (5-10 cm) of sand or fine gravel, keeping it below the mouth's lower lip. A medium chiminea takes roughly 10-20 lb.
- Raise it on a stand. The stand keeps the base dry and lets air reach the bottom. Check it sits level; a 40 in chiminea on a tilted stand can topple.
- Cure with small fires. Start with three or four small fires of paper and kindling, each a little larger, before burning full loads.
- Keep the fire small. Fill no more than about a third of the bowl, and keep flames inside the mouth and below the neck. Overfiring is the usual cause of cracked clay.
- Cover it. Clay soaks up rain; firing a wet chiminea creates steam inside the walls and cracks it. Use a cover or store it dry over winter.
Chiminea or fire pit: size trade-offs
A chiminea suits
- Small patios, since seating is on one side and the zone is about 10 × 8 ft
- Wind, because the chimney carries smoke above head height
- Places where a 15 ft distance is achievable but 25 ft is not
A fire pit suits
- Groups of five or more sitting all round the fire
- Cooking over the flames, which a chiminea mouth makes awkward
- Longer logs: standard 16 in firewood fits a 24 in or larger pit, but only the largest chimineas
For heat without a flame or smoke, see patio heater sizes. Wood-fired cooking in an enclosed dome is covered in the pizza oven size guide, and the layout of the rest of the patio in the patio furniture space guide.
Frequently asked questions
What size chiminea should I buy?
For two to four people on a typical patio, a medium chiminea 36-45 in tall with a 12-15 in mouth is the usual choice. Small ones under 32 in suit two people in a small yard but give little heat; large ones over 50 in need a bigger seating arc and heavier wood loads.
How far should a chiminea be from the house?
The International Fire Code treats a chiminea as a portable outdoor fireplace and requires it to be at least 15 ft (4.6 m) from structures and combustible materials, used according to the manufacturer's instructions. Local codes may set a different distance or ban wood burning on some days.
Is a clay or cast iron chiminea bigger?
At the same height, cast iron and steel chimineas usually have a wider bowl and a larger mouth, so they hold more wood and give more heat. Clay chimineas are often taller for their capacity because of the long, narrow neck, and they weigh about as much as a cast iron model of similar size.
How much sand goes in a clay chiminea?
Enough to fill the bowl to just below the bottom of the mouth, usually 2-4 in (5-10 cm). For a medium chiminea that is roughly 10-20 lb of play sand or builder's sand. The sand keeps the fire's heat off the clay floor, which otherwise cracks.
Can I use a chiminea under a covered patio?
No. The chimney sends hot gases and sparks straight up, and manufacturers require open sky above it. Covered patios, pergolas with slats, umbrellas and tree branches all need to be well clear of the stack.
