Growing a long beard? Most beard trimmers stop at about 10 to 20 mm, which is fine for stubble but useless once your beard is past a few weeks of growth. A long beard needs longer guards, scissors for shaping and a good comb.
This guide covers 10 top-rated trimmers and tools for long beards: six trimmers and grooming kits, plus four tools that make long beards easier to manage. For short beards, see our trimmers for short beards and stubble.
How we chose: we have not tested these products hands-on. The picks are based on each product’s description on its Amazon listing (especially length settings and combs), how well it suits longer beards, and buyer ratings (all 4.3 stars or higher, checked on October 24, 2026). Ratings and availability change, so check the listing before you buy.
Our top 3 picks at a glance
How to trim a long beard
- Wash, dry and comb it out. Trim a dry beard; wet hair looks longer than it is.
- Bulk down with the longest guard you have, or a clipper with a #10 or #12 guard, working downward.
- Shape the length with scissors over a comb, taking small amounts and checking symmetry often.
- Set your neckline about one to two finger-widths above the Adam’s apple with a trimmer and no guard.
- Clean up the cheek line and mustache over the lip.
- Finish with beard oil and a wide comb.
What to look for
| Feature | Why it matters for long beards |
|---|---|

| Number of length settings | More settings make gradual fades and tidy-ups easier |
| Battery or cord | Long beards take longer; corded or long-run batteries help |
| Scissors and comb | Trimmers cannot do everything; length is shaped with scissors |

Mistakes to avoid
- Trimming wet. You will take off more than you meant.
- Starting too short. Always begin with the longest guard.
- Neckline too high. It makes the beard look smaller and the jaw weaker.
- Skipping the comb. Tangles hide uneven spots.
- Too much heat. Use a heated brush on low and keep it moving.
- No beard oil. Long beards get dry and itchy without it; see our beard oil and balm guide.
Frequently asked questions
What length trimmer guard do I need for a long beard?
For beards past a few months of growth, look for combs of 20 to 30 mm, or use clipper guards such as #10 (1-1/4 inch) and #12 (1-1/2 inch). Beyond that, shape with scissors.
Can I use a regular beard trimmer on a long beard?
For the neckline, cheeks and mustache, yes. For bulk and length, you will need long guards or scissors.
How often should I trim a long beard?
Many men tidy the neckline and cheeks every week or two and shape the length every few weeks.
Should I use scissors or a trimmer?
Both. Use the trimmer for lines and bulk, and scissors for length and stray hairs.
Does a beard straightener damage hair?
Too much heat can. Use the lowest setting that works, keep it moving and use it on dry hair.
