If you're anything like me, grooming your dog at home started as a way to save time and money—and maybe avoid a few dramatic trips to the groomer. But as I quickly discovered, getting good results isn’t just about having the right clippers—it’s also about using the right blade size. That’s where understanding the oneisall dog clippers blade size guide really came in handy for me.
Let me walk you through what I learned about blade sizes, how they impact your dog’s haircut, and how to choose the right one based on your dog’s breed and coat type.

Why Blade Size Matters More Than You Think
When I first bought a pair of Oneisall dog clippers, I thought I was all set. I figured: clippers are clippers, right? Just turn them on and start trimming.
Wrong.
Blade size directly affects how much hair you’re cutting off. Each size leaves a different length of hair behind—too short, and you risk irritating your pup’s skin. Too long, and you might not even notice a difference.
The thing I learned (the hard way) is that there's no one-size-fits-all blade for all grooming needs. It depends on your dog’s breed, coat condition, and what kind of finish you’re going for.

Decoding the Numbers: What Do Blade Sizes Mean?
Clipper blade sizes are numbered—#10, #7F, #5, #30, and so on. But don’t let those numbers confuse you.
Here’s a quick breakdown I found super useful:
-
#10 blade leaves about 1/16” of hair — good for sanitary trims (around the belly and rear).
-
#7F blade leaves about 1/8” — great for thick or matted coats.
-
#5 blade leaves about 1/4” — ideal for a tidy look on most breeds.
-
#30 and #40 blades — super short, mostly used with guide combs or for medical trimming.
I recommend checking out the full oneisall dog clippers blade size chart to see exactly what each blade does. It was a game-changer for me when deciding what to use on my Golden Retriever versus my neighbor’s Poodle.

Matching Blade Size to Dog Breed
This was something I didn’t realize at first—different breeds benefit from different blade lengths. Here's what I figured out with a bit of trial, error, and research:
-
?? Poodles or Bichon Frises: Use a #10 or #15 blade for the face and paws, and a #5 or #4 for the body.
-
?? Golden Retrievers or Labs: A #7F or #5 gives a nice, even trim without looking shaved down.
-
?? Shih Tzus or Yorkies: Go with a #7 or #10 for detailed face and ear work.
Remember, using the right blade isn't just about appearance—it’s also about keeping your dog comfortable and safe.

My Grooming Setup: Blades + Combs = Flexibility
I personally love using guide combs with my Oneisall clipper set. They snap onto the blade and let you control the length even more precisely. This is especially useful when I’m grooming around sensitive areas or if I just want to take a bit off the top.
Blades like the #30 or #40 paired with guide combs give a professional finish without risking a too-close cut. It also gives me a lot more flexibility for different grooming styles.

Tips for First-Time Home Groomers
If you’re just getting started, here are a few tips that helped me:
-
Start slow — Choose a medium-length blade (like a #7F) and see how your dog reacts.
-
Keep blades clean and oiled — Dull or dirty blades can pull hair or irritate the skin.
-
Brush your dog first — Mats and tangles will clog the clippers and make grooming harder.
-
Use treats! — Make grooming a positive experience. My dog now associates clippers with snack time.
