Plastic funnels are used for a variety of purposes, including automotive maintenance, industrial workshops, and transferring liquids and powders. They are available in different sizes, from small plastic funnels with a top diameter of 1-1/4 inches to larger ones measuring 4.5 inches by 17 inches. To determine the size of a plastic funnel, it is important to measure both the top diameter and the height. Some funnels also have measurements for the shaft width, bottom opening, and tube length, which can be useful for specific applications. Nalgene plastic funnels, for example, offer a range of sizes and styles to cater to various laboratory applications.

What You'll Learn
Height
When measuring the height of a plastic funnel, it is important to consider the various dimensions that contribute to the overall height of the funnel. Here is a comprehensive guide to help you accurately determine the height of a plastic funnel:
The overall height of a plastic funnel is determined by measuring from the very top of the funnel to its bottom-most point. This measurement includes the height of the funnel's spout or neck, as well as the body of the funnel. It is essentially the total length of the funnel from its highest point to the lowest. This measurement is crucial as it dictates how well the funnel fits into your desired container and how much liquid it can hold.
For example, the Firefly Fuel small plastic funnel has a height of 1-1/2 inches, while their larger funnel measures 2-1/4 inches in height. These dimensions refer to the total height of the funnel, encompassing both the neck and body portions.
In addition to the overall height, you may also want to consider measuring the height of just the funnel's spout or neck. This measurement is taken from the tip of the spout to where it connects to the body of the funnel. The spout height is important as it determines how easily the funnel can reach into narrower containers and openings.
For instance, a heavy-duty food-grade plastic funnel with an overall height of 8 1/8 inches (20.6 cm) has a separate spout height measurement of 2 7/8 inches (7.3 cm). This indicates that the spout contributes significantly to the overall height of the funnel and can be useful for reaching into deeper containers.
Lastly, when measuring the height of a plastic funnel, it is worth noting that some funnels have adjustable or extendable necks. These funnels may have a base height when the neck is retracted, and then you can extend the neck to increase the overall height and reach of the funnel. This feature can be beneficial for versatility, allowing the funnel to accommodate a wider range of containers.

Top width
To measure the top width of a plastic funnel, you will need to use a measuring tool such as a ruler or a measuring tape.
Place the funnel on a flat surface and ensure that it is stable and secure. Next, place the measuring tool at the top opening of the funnel and align it with the edge. Read the measurement at the opposite edge of the funnel's opening to get the top width.
It is important to ensure that the measuring tool is placed accurately and securely to obtain an accurate reading. The top width measurement will be helpful in determining the overall capacity and flow rate of the funnel.
For example, a small plastic funnel may have a top width of 1-1/4 inches, while a larger plastic funnel may have a top width of 2 inches. Similarly, a king-size plastic funnel designed for automotive and industrial use may have a top width of 4.5 inches.

Shaft width
- Measure with Precision: Use an appropriate measuring tool, such as a precision ruler or a digital caliper, to ensure accuracy. Measure across the shaft at its narrowest point.
- Consistency in Units: Ensure that you are using consistent units for your measurements. For example, use either inches or millimetres, but not a combination of both.
- Consider Funnel Shape: The shaft width will vary depending on the shape of the funnel. For example, a straight-sided funnel will have a consistent shaft width along its length, while a tapered funnel will have a variable width.
- Compare with Standard Sizes: You can compare your measurements with standard sizes offered by manufacturers. For instance, a small plastic funnel typically has a shaft width of 1/4 inches, while a larger funnel may have the same shaft width but a greater top and bottom opening.
- Customization: Some plastic funnels may offer the option to cut and customize the shaft width to suit specific applications. This is particularly useful when you need to increase the flow rate for certain fluids.
By following these guidelines, you can accurately measure and understand the shaft width of a plastic funnel, ensuring that it suits your intended applications and fluid types.

Bottom opening
When measuring the bottom opening of a plastic funnel, it is important to remember that the bottom diameter is often smaller than the top diameter. This is because the funnel is designed to guide liquids or solids into a small opening, such as a bottle or container with a narrow neck.
To measure the bottom opening of a funnel, you will need a ruler or measuring tape that can provide measurements in inches or centimetres. Start by placing the funnel on a flat surface with the bottom side facing up. If your funnel has a spout, make sure the spout is also resting flat on the surface.
Next, place the end of your ruler or measuring tape at the centre point of the bottom opening. From this centre point, extend the ruler or tape measure outward to the outer edge of the opening. Note that if your funnel has a spout, you should measure from the centre of the spout opening to the outer edge of the spout.
Finally, record the measurement you have obtained in either inches or centimetres. This will give you the diameter of the bottom opening of your plastic funnel. For example, a common measurement for the bottom opening of a small plastic funnel is 3/16 of an inch, while larger funnels may have a bottom opening of 4.5 inches.

Diameter
The diameter of a plastic funnel is a crucial measurement to consider when selecting the right tool for your needs. The diameter refers to the width of the funnel's opening at the top. This measurement is important as it determines the rate of flow when pouring liquids or fine particles. A larger diameter will allow for a greater flow rate, making it quicker to fill larger containers. Conversely, a smaller diameter is better suited for precision tasks, such as filling small bottles or containers with narrow openings.
When measuring the diameter of a plastic funnel, it is standard practice to use inches as the unit of measurement. Common diameters for small plastic funnels can be as little as 1-1/4 inches, while larger funnels may measure 2 inches or more. For example, a "'king-size' plastic funnel designed for use in automotive settings, industrial workshops, and restaurants has a diameter of 4.5 inches.
The diameter of the bottom opening of the funnel is also an important consideration. While the top diameter affects the flow rate, the bottom diameter ensures that the funnel fits securely into the container being filled. A smaller bottom diameter is necessary for filling small containers, such as essential oil bottles or candle refill openings. For instance, both the small and large plastic funnels offered by Firefly Fuel have a bottom diameter of 3/16 inches.
In addition to the top and bottom diameters, the overall height of the funnel is another factor that influences its functionality. A taller funnel, such as the 12-inch FloTool Measuring Funnel, is useful for reaching into deeper containers. Conversely, a shorter funnel may be more suitable for shallow containers or when space is limited. The height of the funnel also impacts the overall volume it can hold, with taller funnels accommodating larger quantities of liquid or particles.
