A standard 1-gallon paint can measures 6.5 inches wide and 7.5 inches tall — but that’s just one of seven standard paint can sizes available in the USA. From tiny quarter-pint sample cans to massive 5-gallon buckets, every size has a specific purpose.
This guide covers every paint can dimension, exact measurements, and real-world use so you always buy the right size the first time.
Paint Can Sizes Chart — Every Format With Dimensions
Every standard paint container size has a fixed diameter and height. These dimensions matter for storage, transport, and shelf planning — especially when buying multiples for a large project.
| Can Size | Fluid Oz | Liters | Diameter × Height |
|---|---|---|---|
| Quarter Pint | 4 fl oz | 0.12 L | 2.5″ × 2.06″ |
| Half Pint | 8 fl oz | 0.24 L | 2.875″ × 2.875″ |
| Pint | 16 fl oz | 0.47 L | 3.44″ × 3.94″ |
| Quart | 32 fl oz | 0.95 L | 4.25″ × 4.875″ |
| Half Gallon | 64 fl oz | 1.89 L | 5.375″ × 5.875″ |
| Gallon | 128 fl oz | 3.79 L | 6.5″ × 7.5″ |
| 5 Gallon | 640 fl oz | 18.93 L | 12″ × 14.5″ |
Key detail: All sizes from quarter pint through gallon come in metal cans. The 5-gallon format switches to a plastic bucket with a handle — metal at that volume would be impractical to carry and store.
Quarter Pint and Half Pint — Sample and Touch-Up Sizes
The quarter pint is the smallest standard paint can size on the market — just 4 fl oz in a can measuring 2.5 inches wide and 2.06 inches tall. You won’t find it at every hardware store, but specialty paint shops carry it for micro touch-ups and color testing.
The half pint at 8 fl oz sits in a compact 2.875″ × 2.875″ can — small enough to store in a drawer or toolbox. Coverage tops out at around 25 square feet — enough for a door trim, a piece of furniture, or a narrow accent strip.
Pint and Quart — The Detail Work Sizes
The pint holds 16 fl oz (0.47 liters) in a 3.44″ × 3.94″ can, covering approximately 50 square feet. It handles small furniture pieces, window frames, and cabinet doors without leftover waste.
How big is a quart of paint? A quart can measures 4.25 inches wide and 4.875 inches tall, holding 32 fl oz (0.95 liters) — covering roughly 100 square feet in one coat. It’s one of the most practical paint sizes for targeted home projects where a full gallon would leave significant unused paint sitting in storage.
Half Gallon and Gallon — The Room-Painting Standards
The half gallon at 64 fl oz measures 5.375 inches wide and 5.875 inches tall, covering around 200 square feet. Most manufacturers skip this size in their standard lineup — but it fills a useful gap for bathrooms, laundry rooms, and large closets.
The 1-gallon paint can is the most recognized format in any hardware store. Its 1 gallon paint can dimensions land at 6.5 inches wide and 7.5 inches tall, holding 128 fl oz (3.79 liters). One gallon covers 350 to 400 square feet per coat — enough for a standard bathroom, hallway, or large accent wall.
Gallon cans come in two types: lined cans for water-based latex paints to prevent rust, and unlined cans for oil-based paints and solvents that would react with a lining.
5 Gallon — The Large Project Bucket
The 5-gallon paint bucket stands 14.5 inches tall with a 12-inch diameter, holding 640 fl oz (18.93 liters). At this volume the format switches from metal can to a plastic bucket with a handle — necessary for practical carrying at this weight.
One 5-gallon bucket covers approximately 2,000 square feet — enough for two average rooms or one large open-concept space. It’s the most cost-effective format for multi-room projects and full-house repaints, and ensures perfectly consistent color since every drop comes from the same mix.
Spray Paint Can Diameter and Dimensions
Spray paint cans follow completely different dimensional standards than liquid paint containers. A standard spray paint can diameter runs approximately 2.5 to 3.0 inches with a height of 7 to 8 inches for a typical 12 oz aerosol format.
These are pressurized aluminum cans — not the same construction as metal paint tins. Coverage is calculated differently based on spray distance, coat thickness, and surface type rather than square footage per gallon.
Frequently Asked Questions
What are the standard sizes of paint cans?
Standard paint can sizes are quarter pint (4 oz), half pint (8 oz), pint (16 oz), quart (32 oz), half gallon (64 oz), gallon (128 oz), and 5-gallon bucket. The quart and gallon are the most widely available in US hardware and paint stores.
What is the size of a paint can?
The most common paint can size is the 1-gallon, measuring 6.5 inches in diameter and 7.5 inches tall, holding 128 fl oz (3.79 liters). A quart measures 4.25″ × 4.875″ and a pint measures 3.44″ × 3.94″.
What is the diameter of a paint can lid?
Paint can lid diameters match the can body — a gallon lid measures approximately 6.5 inches, a quart lid is 4.25 inches, and a pint lid is 3.44 inches. Metal lids press-fit with a friction seal to keep paint fresh between uses.
How big is a 5 gallon paint can?
A 5-gallon paint bucket measures 12 inches in diameter and 14.5 inches tall, holding 640 fl oz (18.93 liters). It covers approximately 2,000 square feet per coat and comes in a plastic bucket format rather than a metal can due to the weight and volume involved.
Conclusion
Paint can sizes run from a 2.5-inch quarter pint all the way to a 12-inch 5-gallon bucket — and every size serves a different project scale. The quarter pint and half pint handle samples and touch-ups. The pint and quart cover detail and accent work. The gallon is the standard room format. And the 5-gallon bucket is built for large-scale jobs where consistency and cost efficiency matter most.
Now you have every paint can dimension in one place — no guessing, no overbuying.
