What Size Trash Can Fits a 13 Gallon Bag?
A 13-gallon bag fits most standard kitchen trash cans, but the bin’s opening width and height matter more than its gallon rating alone.
How to Measure Your Trash Can
For a practical fit, measure the bin’s opening circumference or perimeter and use it to estimate the minimum bag width. Then add enough material for overlap, rim coverage, and easy removal. Bag length should cover the bin height plus sufficient overhang for securing or tying the bag.
For a round bin:
Minimum flat bag width ≈ bin circumference ÷ 2, plus extra material for overlap and rim coverage.
Example: A 40-inch circumference therefore gives a starting width of about 20 inches before adding extra allowance.
For a rectangular or square bin:
Minimum flat bag width ≈ bin perimeter ÷ 2, plus extra material for overlap and rim coverage.
Example: A bin with a 12 × 10 inch opening has a perimeter of 44 inches, giving a starting flat bag width of about 22 inches before adding extra allowance.
For detailed measuring formulas for round, square, and rectangular bins, see our full guide: How to Measure for the Right Trash Bag Size.
What If the Bag Doesn’t Fit?
| Problem | Likely Cause | Solution |
|---|---|---|
| Bag too short | Bin height is taller than expected | Choose a bag with longer length (30″ instead of 28″) |
| Bag won’t stay on rim | Bag width is too narrow for the opening | Choose a wider bag or drawstring style |
| Bag overhangs too much | Bag is too long for the bin | Choose a shorter length or flat-seal bag |
What Thickness Is Best for a 13 Gallon Trash Bag?
There is no single standard thickness for a 13-gallon trash bag. The appropriate thickness depends on the material, bag construction, load, and type of waste.
Common Thickness Ranges*
| Application | Common Thickness Range* |
|---|---|
| Light household waste (paper, dry trash) | ~0.7–0.8 mil |
| Standard kitchen waste | ~0.8–1.0 mil |
| Wet or heavier waste (food scraps) | ~0.9–1.2+ mil |
| Heavy-duty applications | 1.2+ mil |
*These are general reference ranges, not industry requirements. Actual bag performance depends on material, film structure, dimensions, seal strength, and the type of waste.
What Are 13 Gallon Trash Bags Made Of?
| Material | Properties | Best For |
|---|---|---|
| LDPE | Soft, flexible, good stretch | Kitchen waste, food scraps |
| LLDPE | Excellent tear and puncture resistance | Heavy-duty, commercial use |
| HDPE | Rigid, cost-effective, lightweight | Lightweight waste, recycling |
| Certified compostable blend | PBAT/PLA and other compostable formulations | Food-waste collection, sustainability programs |
| If you need… | Consider… |
|---|---|
| Lowest cost | HDPE |
| Flexibility | LDPE / LLDPE |
| Heavy-duty performance | LLDPE |
| Certified compostability | Certified compostable blend |
| Food-waste collection | Certified compostable bag |
For buyers looking for a compostable option, certification should be verified for the finished bag, not simply the raw material.
13 Gallon Trash Bag Types: Which Closure Is Best?
| Closure Type | Description | Best For |
|---|---|---|
| Drawstring | Integrated strings that cinch closed | Most user-friendly; easy tying and carrying |
| Flap-tie / Quick-Tie | Extended flaps that cross-tie | Simple, no extra twist-ties needed |
| Handle-tie | Reinforced handles for easy tying | Heavy loads; secure transport |
| Open top (flat) | No closure; requires separate ties | Commercial can liners; cost-effective |

Are There Compostable 13 Gallon Trash Bags?
Yes. Compostable 13-gallon trash bags are available for household and food-waste applications. They are commonly made from compostable polymer blends such as PBAT and PLA, while certification applies to the finished bag and its intended application. For certified products, verify that the finished bag—not just the raw material—has the required compostability certification applicable to your target market and intended disposal environment.
For a detailed explanation of compostability standards such as ASTM D6400, EN 13432, and BPI certification, see our Compostable Certifications Guide.

FAQ
How big is a 13 gallon trash bag?
Common 13-gallon trash bags are often around 24–27 inches wide × 28–33 inches long, depending on the manufacturer and bag type. For many standard kitchen bins, about 24 × 28–30 inches is a useful starting point.
How many liters is 13 gallons?
13 US gallons = approximately 49.2 liters.
What size trash can fits a 13 gallon bag?
A 13-gallon bag is designed for most standard U.S. kitchen trash cans, but the exact fit depends on the bin’s opening and height. Measure your bin before choosing a bag, rather than relying on gallon capacity alone.
Can a 13 gallon trash bag fit a 10 gallon trash can?
It depends on the physical dimensions of the bag and the bin. A 13-gallon bag may fit a 10-gallon can if the bag’s width and length match the bin’s opening and height. However, it’s always better to measure the bin’s opening and height before choosing a bag.
What is the difference between a 13 gallon and 8 gallon trash bag?
An 8-gallon trash bag is smaller, typically used for bathroom or small office bins, while a 13-gallon bag is the standard size for kitchen trash cans. The main difference is capacity and physical dimensions, but exact fit depends on the specific bag dimensions rather than the gallon rating alone.
What is the difference between a 13 gallon and 30 gallon trash bag?
A 30-gallon trash bag is significantly larger, commonly used for outdoor bins, garage waste, or commercial settings. A 13-gallon bag is designed for standard kitchen use. The gallon rating indicates capacity, but physical dimensions vary by manufacturer and bag style.
Are 13 gallon trash bags the standard kitchen size?
In the U.S., 13 gallons is one of the most common sizes for standard U.S. kitchen trash cans, but not all kitchen bins use 13-gallon bags. Always measure your bin’s opening and height for the best fit.
Are there compostable 13 gallon trash bags?
Yes. Compostable 13-gallon trash bags are available with certifications such as ASTM D6400 or EN 13432. They are typically made from compostable blends like PBAT/PLA, with certification applying to the finished bag.
What thickness should a 13 gallon trash bag be?
For standard household use, ~0.8–1.0 mil is a common range. For heavy or wet waste, consider ~0.9–1.2+ mil or thicker.
What is the difference between drawstring and flap-tie bags?
Drawstring bags have integrated strings built into the bag’s rim that you pull to close and carry.
Flap-tie bags (like Glad Quick-Tie) have extended flaps that you cross-tie at the top without additional twist ties.
Can I print my logo on 13 gallon trash bags?
Yes. Manufacturers can provide flexographic printing for logos, disposal instructions, and brand messaging.
What are typical lead times for custom 13 gallon trash bags?
Samples: ~7 days
Custom bulk orders: ~15–20 days
Conclusion
Choosing the right 13-gallon trash bag comes down to three things: bin dimensions, waste type, and material preference.
- Measure your bin — opening width and height matter more than gallon rating
- Choose the right thickness — match it to your waste
- Select compostable if you need certified eco-friendly options
