Sizing in Spring Clamps
Spring clamps come in a variety of sizes, and it can be easy to get lost in the different dimensions if you’re not sure what you’re looking for. When purchasing a spring clamp it is essential to be aware of the sizing and whether it is appropriate for your task.
Usually available online in a pack of ten or twenty, this spring clamp is a mini but mighty tool useful in situations where space is tight. The opening is just large enough to forcefully hold materials down but small enough to fit into spaces larger clamps cannot access. However, the clamp is very small and not the best choice for projects where a greater clamping force or jaw opening is required. To help visualize its size, imagine a spring clamp that fits into the palm of your hand.
Small- 3.75” and 4.5”
Despite being smaller than your average spring clamp, the three to five-inch long spring clamps pack a lot of strength and come in very handy. This size is perfect for those who are looking for spring clamps to help out in the photo studio. Activities like securing backdrops on standard photography background stands are where a good heavy-duty spring clamp is ideal. This helps you focus on the shoot itself rather than worrying about technicalities.
6 inches in length is the standard size for most spring clamps and is the best choice for those looking to buy a spring clamp for woodworking and carpentry. This size spring clamp is most commonly used for the task of fastening materials in place while gluing so the adhesive sets properly. If you are interested in a spring clamp that will be heavy-duty and assist you in various DIY projects, then this is the size for you.
The larger spring clamps are when you need a spring clamp that is a little more heavy-duty and firm than standard. For holding down material like tarp or securing wooden boards that are thicker in diameter, a larger spring clamp may be the better option. However, these can often be difficult to grasp with one hand due to their length so make sure a large clamp is what you really need!
What Is Jaw Opening?
After size, the jaw opening will help you figure out which spring clamp will be most useful for your project. Some spring clamps only open up to 1 inch while others can have an opening of 4 inches. If the jaw of the spring clamp is unable to wrap around the material you want to hold down, then you won’t be able to use it.
How To Decide Which Material Is Best
Before committing to buying a spring clamp, make sure its material is compatible with your project. If you are looking for a product that will withstand wear and tear then a spring clamp made of plastic would not be a good option. Nylon spring clamps are best for most small tasks while muslin is more heavy-duty. Metal spring clamps are the best option if you are looking for something more long-term.

The Importance of Clamping Pressure and Flexibility
The best spring clamp is one that clamps with great clamping force without making you break into a sweat in the process. Flexible handles and a strong grip are essential to getting the job done and should be high on your list of priorities when buying a spring clamp. A well-designed spring clamp built with high-quality materials is what you should be on the lookout for.
Parts of a Spring Clamp
A spring clamp has two jaws responsible for holding on to the material that is to be clamped. Jaws often have PVC-coated or rubber tips at the end of them to protect the material from being damaged or marred in the clamping process. Sometimes these tips are adjustable and can swivel to hold odd-shaped material down at the best angle.
There are two handles in a spring clamp. Placing slight pressure on the handle opens the jaws of the clamp. A good spring clamp does not have slippery handles. You will find that handles are often coated in PVC or rubber. This is to protect your skin from injury.
This is where spring clamps get their name from. All spring clamps have a coiled spring positioned between their jaws and handles. The spring is what keeps the jaws of the spring clamp closed until pressure is applied to its handles.
