Not sure which size to buy? Most US homes use a 13-gallon (about 50-liter) kitchen trash can. The usual range runs from 12 to 16 gallons.
This kitchen trash can size guide gives you real dimensions in inches, capacity in gallons and liters, bag fit, and cabinet clearance. Measure once, buy once.

Standard Kitchen Trash Can Sizes and Typical Dimensions
Store shelves back this up. The popular 13-gallon tall kitchen bag is sold as the right fit for most kitchen garbage cans.
Here is a quick chart. Sizes are approximate and vary by brand.
| Size | Gallons | Liters | Typical footprint | Best for |
|---|---|---|---|---|
| Small | 4 to 8 | 15 to 30 | About 10 to 12 in wide | Studios, apartments |
| Standard | 12 to 13 | 45 to 50 | About 13 to 17 in wide | Most homes |
| Large | 14 to 16 | 53 to 60 | About 17 to 20 in wide | Big families |
| Extra large | 20 | 76 | About 19.5 in round | Garages, huge kitchens |
Shape matters as much as size. Round cans waste corner space. Rectangular and slim cans tuck against cabinets and save floor space. A semi-round can hugs a wall.
Kitchen Trash Can Capacity: Gallons, Liters and Bag Sizes
One US gallon equals about 3.79 liters. So a 13-gallon can holds about 49 liters. Use this table to convert.
| Gallons | Liters |
|---|---|
| 5.3 | 20 |
| 7.9 | 30 |
| 12 | 45 |
| 13 | 49 |
| 16 | 61 |
| 20 | 76 |
Now the part most guides skip: trash bag size. A standard 13-gallon tall kitchen bag is about 24 inches wide and 28 inches long. If your can is a bit taller, an extra-tall 13-gallon bag measures 24 x 31 inches and gives you 4 inches more height.
A good bag hangs a few inches over the rim. If it keeps slipping in, size up. Also watch dual-compartment cans. A 46-liter split can gives you only a 30-liter trash side and a 16-liter recycling side. The label number is not your trash capacity.

How to Choose the Right Kitchen Trash Can Sizes for Your Home
Start with people. Americans produced about 4.9 pounds of municipal waste per person per day in 2018, per EPA data. Not all of it comes from your kitchen. Still, more people means more bags.
| Household | Good size |
|---|---|
| 1 to 2 people | 8 gallons (30 L) |
| 3 to 4 people | 13 gallons (50 L) |
| 5 or more | 13 to 16 gallons, plus a recycling bin |
Cook a lot? Go up one size. Take the trash out daily? Go down one.
A round 20-gallon can is about 19.5 inches across and nearly 23 inches tall. That is a big bite of floor. It also lets food waste sit for days, which invites odor. It works in large kitchens, big households, or a pantry.
Check lid clearance before you buy. One 45-liter step can stands 25 inches tall but reaches about 34.8 inches with the lid open. Tuck it under a low counter and the lid may hit the wood.
Lid style and material matter too. Step-on, swing-top, and touchless lids each need different space. Stainless steel looks sleek and wipes clean. Plastic is light and cheaper. Pick the size first, then the style.
Under-Sink and Pull-Out Kitchen Trash Can Sizes Guide
Cabinet cans follow tighter rules. Most cabinet trash cans hold between 10 and 30 liters, or 2.5 to 8 gallons. Bigger cans rarely fit.
Measure these three spots first:
- Opening width: measure the clear gap, not the cabinet label. It is often narrower.
- Depth: from the door to the back wall.
- Height: up to the lowest pipe or garbage disposal.
Standard pull-out cabinets run about 12 to 24 inches wide, and a cabinet can near 15 inches wide and 20 inches tall is common, per this guide. For tight spots, try a slim, tilt-out, or double-bin design. The classic mistake is forgetting the door swing. Test it with a cardboard box the same size.
