Difference Between #7 and #10 Clipper Blades: Which Cuts Shorter?
When grooming pets, especially dogs and cats, choosing the right clipper blade is essential to achieve the desired coat length and ensure the comfort and safety of your pet. One common question among pet owners and professional groomers alike is:
Does a #7 or #10 blade cut shorter?
Understanding Clipper Blade Numbers
Before diving into the specific differences between #7 and #10 blades, it's important to understand how blade numbering works. Generally:
- The higher the blade number, the shorter the cut.
- The lower the blade number, the longer the hair remains after clipping.
With this in mind, a #10 blade cuts closer to the skin than a #7 blade.
Blade Lengths: #7 vs #10
Let’s break down the cutting lengths:
- #10 blade: Cuts hair to about 1/16 inch (1.5 mm). Ideal for sanitary trims, feet, face, and around the eyes.
- #7 blade: Cuts to approximately 1/8 inch (3.2 mm). Commonly used for body clips on matted or coarse coated dogs.
So when comparing the two, the #10 blade cuts significantly shorter than the #7.
When to Use a #10 Blade
The #10 blade is best suited for:
- Sanitary areas (under tail, belly, groin)
- Inside ear flaps and pads of paws
- Veterinary prepping before surgery
- Cooling the skin by removing more hair close to the body
Additionally, it is often a go-to blade for general body clipping in some short-haired breeds.
When to Use a #7 Blade
Pet owners frequently turn to the #7 blade for:
- Full body clipping on dogs prone to matting (like spaniels and retrievers)
- Summer clips to reduce coat without shaving too close
- Pre-shearing before uniform body trimming
It delivers a slightly longer cut, which can be more comfortable for pets during cooler months.
Safety and Skin Sensitivity
Because the #10 blade cuts shorter, it is also more likely to cause razor burn or irritation if not used properly. Groomers should always:
- Check blade temperature regularly to avoid overheating
- Use clipper coolant or lubricant
- Be extra cautious in sensitive areas with thin skin
The #7 blade, while safer in most cases, still requires careful handling, especially if the coat is matted, as it can tug and make pets uncomfortable.
Blade Material and Quality
Whether you choose a #10 or #7 blade, always consider the material:
- Steel blades: Durable, cost-effective, and easy to sharpen
- Ceramic blades: Stay cooler longer, but are more brittle
- Titanium-coated blades: Offer reduced friction and durability for heavy use
Clipper Blade Compatibility
Ensure your blade matches your clipper brand. Most major clippers (like Andis, Oster, Wahl) are compatible with detachable blades, especially #10 and #7 blades, but always verify fit before purchasing.
Tips for Better Grooming Results
To get the best clip:
- Wash and dry the pet’s coat beforehand
- Brush out tangles to prevent snagging
- Use guides or combs if you want a longer cut with a #10 blade
- Work slowly and gently, especially in sensitive areas
Conclusion: Which Blade is Right for Your Pet?
In summary,
the #10 blade cuts shorter than the #7 blade, delivering a closer trim that’s suited for precise grooming tasks and medical prep. The #7 blade is ideal for fuller body trims where a bit more coat is left for warmth or style.
Always consider your pet’s coat type, sensitivity, and seasonal needs before choosing between these two popular blade sizes.
