⚡ Quick Answer: A 13 gallon trash can holds about 49.2 liters or 3,000 cubic inches of waste. Most models stand 23 to 26 inches tall, with a footprint of roughly 12 to 18 inches wide and 12 to 17 inches deep. The Glad and Sterilite standards measure around 16-by-13-by-25 inches, making 13 gallons the default size for U.S. kitchens of two to four people.
You bought a sleek kitchen bin online, dragged it home, and now it’s wedged under the counter with the lid jammed against the cabinet — or floating in space because the footprint is smaller than you pictured. A 13 gallon trash can sounds like a standard size, but actual dimensions swing by more than four inches between brands. After eight years measuring household products for product reviews at BusinessComputingWorld, I’ve learned that volume ratings hide the dimension that actually matters: vertical clearance.
Thirteen US gallons equals exactly 49.21 liters or 3,003 cubic inches, using the official conversion of 231 cubic inches per US gallon defined by the National Institute of Standards and Technology. That raw volume translates into trash can dimensions ranging from 23.13 inches tall on the compact Hefty 13.3 Gallon Touch Lid (15.85″ L × 12.85″ W × 23.13″ H) to 27.9 inches on the slim iTouchless 13 Gallon Sensor model (12.8″ L × 10.8″ W × 27.9″ H, reaching 35.8″ with the lid open). The Sterilite TouchTop 13 Gal Wastebasket sits between them at 16 3/8″ L × 12 5/8″ W × 24 3/4″ H, which has become the de facto reference dimension cited by retailers like Lowe’s and Amazon. The shape decides the trade-off: rectangular slims hug walls, semi-round models need 16-inch diameters, and step-pedal lids add 2 to 4 inches of swing clearance you have to account for before buying.
13 Gallon Trash Can Dimensions: The Numbers That Actually Matter
A 13 gallon trash can typically measures 23 to 28 inches tall, 12 to 18 inches wide, and 12 to 17 inches deep. The most common reference dimension is 16″ L × 13″ W × 25″ H, which holds 49.2 liters and fits standard tall kitchen bags. Slim rectangular models prioritize height; semi-round and step-pedal models trade footprint for shape.
Volume is the headline number. Dimensions are the number that decides whether your purchase works. Here’s the data range across the bestselling 13 gallon models on the U.S. market in 2026:
| Model | Length | Width | Height | Type |
| Glad 13G Step Pedal | 18″ | 14.7″ | 25″ | Rect |
| Sterilite 13 Gal TouchTop | 16 3/8″ | 12 5/8″ | 24 3/4″ | Rect |
| Hefty 13.3 Gallon Touch Lid | 15.85″ | 12.85″ | 23.13″ | Rect |
| iTouchless 13G Sensor (slim) | 12.8″ | 10.8″ | 27.9″ | Slim |
| Rubbermaid 13G Spring-Top | 17.2″ | 14.9″ | 25.5″ | Rect |
| simplehuman 50L Semi-Round | ~16″ | ~13″ | ~26″ | Round |
The footprint range — 10.8 to 18 inches wide — has practical consequences. A 10.8-inch slim model frees up 7.2 inches of floor space versus an 18-inch rectangular model in the same gallon class. That’s the gap between fitting between your refrigerator and pantry door and not fitting at all. Height matters in the opposite direction: a 27.9-inch model with a 35.8-inch lid-open clearance fails immediately under any standard 30-inch upper cabinet.
If you need a faster mental anchor for what 13 inches actually looks like in the room, this real-world size guide for 13 inches — covered alongside other common kitchen dimensions in our object size cluster — gives you instant calibration.
How Big Is a 13 Gallon Trash Can in Real-World Terms?
Thirteen gallons is roughly the volume of 104 standard 16-ounce water bottles, a full mid-size kitchen sink filled to the brim, or two and a half full grocery bags stacked together. It holds about 20 to 25 pounds of typical household waste at standard-duty bag thickness, according to bag manufacturer specifications published by Trash Rite and ShinHigh Bio.
Reaching for a body-based reference? The bin stands roughly from your knee to your mid-thigh on an average-height adult. Picture a stack of three reams of printer paper inside it and you’ve filled about half. Picture a full laundry basket dumped in and you’re at capacity.
The 13 gallon size hits a specific sweet spot that explains its dominance. According to Trash Cans Unlimited (2025), a family of four generates 137 pounds of waste weekly based on the EPA’s figure of 4.9 pounds of municipal solid waste per person per day reported in the 2018 Facts and Figures report. That weekly load translates to six or seven full kitchen bags. A single 13 gallon can absorbs roughly one day’s worth from a four-person household before it needs emptying — fast enough to keep odors down, slow enough to avoid the daily-trash-run grind. Step down to 10 gallons and you’re emptying every 16 to 18 hours during normal cooking cycles. Step up to 20 gallons and the bag gets too heavy for one-handed removal once it’s two-thirds full. Thirteen gallons exists where waste generation, bag strength, ergonomics, and standard cabinet geometry intersect.
13 Gallons vs. Other Common Trash Can Sizes
Comparison fixes intuition faster than absolute numbers. Here’s how 13 gallons stacks up against every common indoor and outdoor size in the U.S. market:
| Capacity | Liters | Typical Height | Typical Footprint | Best Use |
| 3 gal | 11.4 L | 12–14 in | 10″ diameter | Bathroom, bedside |
| 7 gal | 26.5 L | 16–18 in | 12–14 in wide | Office, small kitchen |
| 10 gal | 37.9 L | 18–20 in | 14–15 in wide | Couples, apartments |
| 13 gal | 49.2 L | 23–28 in | 12–18 in wide | Standard kitchen, 2–4 people |
| 20 gal | 75.7 L | ~31 in | 16–20 in wide | Large family, garage |
| 32 gal | 121.1 L | 33–40 in | 18–22 in wide | Outdoor curbside |
| 64 gal | 242.3 L | ~42 in | ~25 in wide, wheeled | Municipal collection |
Two ratios worth memorizing: 20 gallons is 54% larger than 13 gallons in volume, but only 3 to 5 inches taller and 2 to 4 inches wider. The 32 gallon outdoor bin is 2.5× the volume of your kitchen can. And the municipal 64 gallon wheeled cart? That’s nearly five times what sits in your kitchen — useful context when you’re lining up curbside pickup volume against your interior collection cadence.
For finer-grained spatial reference on the heights involved, the practical visualization in our 20-inch size guide maps roughly to a 7-gallon can, while the references in our size guide for 18 inches correspond to the height of compact 10-gallon models.
Will a 13 Gallon Trash Can Fit Under Your Kitchen Sink?
In most kitchens, no — and this is where the majority of online buyers get burned. Standard under-sink cabinets offer only 16 to 20 inches of usable vertical clearance once you subtract the P-trap, garbage disposal, and supply lines, according to data published by Trash Cans Unlimited in 2025. A 13 gallon can needs a minimum of 23 inches of vertical clearance — and that’s before you account for the lid mechanism.
Run this five-step check before ordering:
- Measure A: vertical distance from the cabinet floor to the lowest pipe or disposal.
- Measure B: internal cabinet width minus pipe intrusion (usually 14–18 inches usable).
- Measure C: depth from the cabinet face to the back wall behind the pipes.
- Add 2 inches to the can’s listed height for step-pedal swing clearance.
- Subtract 1 inch from each footprint dimension for bag overflow and ease of bag changes.
If A is under 22 inches, the 13 gallon class is wrong for under-sink. You need a 7 to 10 gallon slim model, or you move the bin to a freestanding location. A pull-out drawer system adds 3 to 5 inches of mechanical depth on both axes — meaning a 16-inch wide cabinet realistically fits a 10-inch-wide bin once the slides are installed.
Two viable workarounds: a slim rectangular model (the iTouchless 12.8″ × 10.8″ footprint clears most pipe configurations at 27.9 inches tall, provided your cabinet has a 28-inch interior), or two side-by-side 7-gallon bins for separated trash and recycling — which most kitchens actually need anyway.
How Much Trash Does a 13 Gallon Can Actually Hold?
A 13 gallon can holds 20 to 25 pounds of typical household waste at standard 0.7-mil bag thickness, scaling to 30–40 pounds at 1.0-mil heavy-duty and 50+ pounds at 2.0-mil extra-heavy-duty. Empty, the can itself weighs between 2 and 6 pounds depending on material: plastic models like the Sterilite 13 Gallon TouchTop come in around 4 pounds, while stainless step-pedal models like the Umbra Brim run 6 pounds.
Practical capacity by household size:
| Household | Daily Fill Rate | Days to Full | Bag Cost/Week |
| 1 person | 1.6 gal/day | 8 days | $0.35–0.50 |
| 2 people | 3.2 gal/day | 4 days | $0.70–1.00 |
| Family of 4 | 6.5 gal/day | 2 days | $2.10–3.00 |
| Family of 5+ | 8.0+ gal/day | 1.6 days | $2.80–4.00 |
Daily fill estimates assume the EPA municipal solid waste rate of 4.9 pounds per person per day (which roughly equates to 1.5–1.8 gallons of volume), adjusted for composting and recycling that diverts about 32.1% of household waste.
What actually fits inside? Common items at full 13 gallon capacity:
- Eight large pizza boxes flattened
- Three full plastic grocery bags
- 104 standard 16-ounce water bottles (uncompressed)
- One full laundry basket of soft trash
- Two days of food waste for a family of four
Is 13 Gallons Right for You? The Volume-Fit-Frequency Matrix
The 13 gallon size is the default, not the universal answer. Use this decision matrix to confirm before buying — three dimensions, three honest questions, one clear answer.
| Volume Need | Floor Space Available | Emptying Frequency | Recommended Size |
| 1–2 person, low waste | Under 14″ wide | Every 4–6 days | 10 gal slim |
| 1–2 person, low waste | Over 14″ wide | Every 4–6 days | 13 gal rectangular |
| Family of 3–4 | Under 14″ wide | Every 1–2 days | 13 gal slim |
| Family of 3–4 | Over 14″ wide | Every 2–3 days | 13 gal rectangular ✓ |
| Family of 5+ | Over 16″ wide | Every 1–2 days | 16–20 gal |
| Heavy cooks/no compost | Over 16″ wide | Every 2 days | 16–20 gal |
The matrix exposes a common mistake: choosing capacity by family size alone. Floor space and emptying tolerance matter just as much. A family of three that hates lugging bags wants 20 gallons. A family of three with 12 inches of clearance between counter and wall needs a 13 gallon slim regardless of preference.
The contrarian truth most kitchen-design guides skip: two 13 gallon cans beat one 20 gallon can for any household above two people. Standard bags fit both, weight stays manageable for one-person removal, and trash-versus-recycling separation comes built in. The aesthetic hit is real. The functional gain is bigger.
Matching 13 Gallon Trash Bags to Your Can
The 13 gallon bag standard, also called the tall kitchen bag, measures roughly 24 inches wide by 27 to 31 inches tall when laid flat, with bag manufacturers like Hefty and Glad varying height to indicate fit tier. The math: for a rectangular can, your bag width (laid flat) should equal the can’s rim perimeter divided by 2. Your bag height should equal can height plus one-quarter of can width plus 4 inches of overhang.
Example calculation for a 15″W × 12″D × 25″H can:
- Bag width: (15 + 12 + 15 + 12) ÷ 2 = 27 inches
- Bag height: 25 + (12 ÷ 2) + 4 = 35 inches (use 31″ tall kitchen bag for a snug fit)
Bag mil thickness sets weight capacity per the ShinHigh Bio (2026) thickness guide: 0.7–0.9 mil holds 20–25 lbs; 1.0–1.5 mil holds 30–40 lbs; 2.0+ mil holds 50+ lbs. For typical mixed household waste, 0.9 mil is the value sweet spot. For wet food waste, sharp cans, or yard debris, jump to 1.2 mil minimum.
If you’re sizing a different room — bathroom, office, or garage — the principle is identical: measure circumference and height, then translate. The conversion logic is the same one we use in our guide to 15 inches for visualizing common product dimensions before ordering, and the spatial reasoning carries over directly to bag sizing.
Frequently Asked Questions
How tall is a standard 13 gallon trash can?
A standard 13 gallon trash can stands 23 to 28 inches tall, with 25 inches as the most common height across major brands like Glad, Sterilite, and Rubbermaid. Slim sensor models reach up to 27.9 inches, while compact step-pedal models stay around 23 inches. Always add 2 to 4 inches for lid-open clearance.
How many liters is a 13 gallon trash can?
A 13 US gallon trash can holds exactly 49.21 liters, using the conversion of 1 US gallon = 3.785 liters defined by the National Institute of Standards and Technology. International markets often label this same can as 50 liters, which is the closest standard metric round-up.
Will a 13 gallon trash can fit under a standard kitchen sink?
Usually no. Standard under-sink cabinets offer 16 to 20 inches of usable vertical clearance after pipes and disposal, while a 13 gallon can needs at least 23 inches. A 7 to 10 gallon slim model fits most under-sink spaces; 13 gallon belongs in a freestanding location next to the counter or in a deep pantry pull-out.
How much does a 13 gallon trash can hold in pounds?
A 13 gallon trash can holds 20 to 25 pounds of typical mixed household waste at standard 0.7–0.9 mil bag thickness, 30 to 40 pounds at 1.0–1.5 mil heavy-duty, and over 50 pounds at 2.0+ mil extra-heavy-duty thickness. Weight capacity is limited by the bag, not the can itself.
Is a 13 gallon trash can big enough for a family of four?
Yes, for typical kitchen use with 1- to 2-day emptying cycles. Per EPA data, a family of four generates roughly 137 pounds of waste weekly — about 6 to 7 full 13 gallon bags. If you cook heavily, don’t compost, or hate frequent bag changes, step up to 16 to 20 gallons or run two 13 gallon cans for trash and recycling.
Choosing Your 13 Gallon Trash Can: Next Steps
A 13 gallon trash can is the right size for most U.S. households of two to four people, fitting in 49.2 liters of waste across a footprint that ranges from 11 to 18 inches wide and stands 23 to 28 inches tall. The right model depends on the gap between numbers and reality in your specific kitchen.
Three actions to lock this in before you buy:
- Measure your intended spot now — width, depth, and vertical clearance to the lowest obstacle (cabinet, countertop overhang, or upper shelf). Write the three numbers down before browsing.
- Decide your emptying tolerance — if you’ll empty more than every 2 days, you want 20 gallons or two 13s. If less than every 2 days, 13 gallons is correct.
- Buy bags last — calculate width and height from your finalized can dimensions, then choose mil thickness based on your wettest waste category.
The 13 gallon size dominates U.S. kitchens because it sits at the intersection of four constraints: weekly waste output for an average family, standard bag dimensions, cabinet geometry, and one-handed bag removal weight. Pick the dimensions that fit your space first, the volume second, and the brand last.

How much does a 13 gallon trash can hold in pounds?
A 13 gallon trash can holds 20 to 25 pounds of typical mixed household waste at standard 0.7–0.9 mil bag thickness, 30 to 40 pounds at 1.0–1.5 mil heavy-duty, and over 50 pounds at 2.0+ mil extra-heavy-duty thickness. Weight capacity is limited by the bag, not the can itself.
Is a 13 gallon trash can big enough for a family of four?
Yes, for typical kitchen use with 1- to 2-day emptying cycles. Per EPA data, a family of four generates roughly 137 pounds of waste weekly — about 6 to 7 full 13 gallon bags. If you cook heavily, don’t compost, or hate frequent bag changes, step up to 16 to 20 gallons or run two 13 gallon cans for trash and recycling.
Choosing Your 13 Gallon Trash Can: Next Steps
A 13 gallon trash can is the right size for most U.S. households of two to four people, fitting in 49.2 liters of waste across a footprint that ranges from 11 to 18 inches wide and stands 23 to 28 inches tall. The right model depends on the gap between numbers and reality in your specific kitchen.
Three actions to lock this in before you buy:
- Measure your intended spot now — width, depth, and vertical clearance to the lowest obstacle (cabinet, countertop overhang, or upper shelf). Write the three numbers down before browsing.
- Decide your emptying tolerance — if you’ll empty more than every 2 days, you want 20 gallons or two 13s. If less than every 2 days, 13 gallons is correct.
- Buy bags last — calculate width and height from your finalized can dimensions, then choose mil thickness based on your wettest waste category.
The 13 gallon size dominates U.S. kitchens because it sits at the intersection of four constraints: weekly waste output for an average family, standard bag dimensions, cabinet geometry, and one-handed bag removal weight. Pick the dimensions that fit your space first, the volume second, and the brand last.
