Explaining The Dog Clipper Blade Size Chart

There are lots of different blade sizes for your dog clippers for the desired look you want for your dog. Those with a higher blade number cut the hair closer to the skin than those with a lower number which will leave more hair. The lower clipper numbers usually come in both skip-tooth, and fine-tooth designs, whereas sizes 9 and an above will only come in the skip tooth designs. The most common sizes of the dog clipper blades come in sizes 3, 4, 5, 7, 9, 10, 15, 30, 40, and 50.

The highest numbered blades will give the closest cuts for your dog’s hair and the different areas of your dog’s body. Around the face of your dog, you will want a closer shave and then longer hair on their back and tail. Each different breed has different recommendations for the blade size to use. Here is a small and instructing guide to help you find the blade size you need to get the perfect cut for your dog’s hair.

Dog Clipper Blade Size Chart

If you have a dog that is mixed breed there is no need to worry. There is still the possibility of clipping your dog’s hair on your own. You might just find it more difficult to find a blade size that suits the hair of your mixed breed dog. Once you have identified the type of fur or hair your dog has, it will be easier to find the right blade sizes. If you need the recommendation or some help talk to your vet or groomer for some advice.

Types of Fur

If you can identify the type of fur your dog has it will be easier to know and find out what clipper size you will need to give your dog the perfect cut. There are three main types of dog hair — wiry, smooth, and curly. Those with smooth coats need to use a fine-tooth blade sized 7 for the legs and body, and then shears for the rest of the body. You should use a fine-tooth blade sized 5 or 7 for those dogs with wiry coats on the tail and body while using a size 10 for the ears. For dogs with curly coats, you should use a fine-tooth blade sized 3 or 4 for the body and then size 10 for the face.

Skip Tooth Blades and Fine Tooth Blades

These are the different types of blades you can use for your dog’s hair. The difference between the two refers to how much space is between the teeth of the blade. Fine-tooth blades have little space between the teeth, whereas the skip tooth blades have some gaps in between the teeth. The skip-toothed blades are normally used for the first cut during a groom, to get the excess hair off before doing a more precise cut with the fine-tooth blade. The skip-tooth blades are better for cutting curly, thick or matted dog hair. Skip-tooth blades leave the dog’s coat looking layered as they do not trim the hair evenly. These are used by groomers for the first initial cut before then washing and finishing the groom with a fine-toothed blade.


You can use this guide to help you to choose the right grooming blades you need to give your dog the best cut possible. The difference in sizes is used for different breeds with different types of hair or fur that your dog might have. You can use the size chart to work out the best blade size for the type of dog you have and purchase the right blades and clippers for this type of dog. Along with specific sizes for specific types of dogs, the type of blade is important. Remember, skip-tooth blades are used for the initial cut of the coat, while the fine-tooth blades are used for more accurate cuts around the face and tail. The different types of coats of dogs — wiry, smooth, and curly — all require different sizes and types of blades.
