- Works with a tweak
- Why
- It hardens lines on a jaw that is already angular. On the plus side it adds width at the jaw, which the lower face lacks.
- Shape it
- round the corners instead of squaring them
- Upkeep
- lines every few days, length weekly
Put the width below your cheekbones
Your cheekbones form the widest line of a diamond face. Your forehead and jaw are narrower, and your chin comes to a point. Width at the forehead and chin softens the cheekbones' prominence. Extra volume at cheekbone level exaggerates it.
A boxed beard can help fill out the lower outline, but placement matters. Keep the added width around your jaw rather than building bulk beside your cheekbones.
The free face-shape finder reads jaw-to-cheekbone width from one selfie, on your device. That measurement helps you check the width difference you're shaping around.
Round the corners instead of squaring them
Keep the beard's edges clean, but round the corners instead of squaring them. A defined line doesn't have to end in a sharp angle. You're keeping the width while softening the outline.
Look at the lower corners when you check your short boxed cut. If they form hard points, soften those turns without cutting away all the width beside your chin.
When asking a barber for this shape, describe both parts: a short full beard and rounded lower corners. That makes your request clearer than asking for a boxed beard alone.
Set the lines early and maintain them
Set your cheek and neck lines from week two. Growing the beard first and shaping it later leaves the outline undecided while the hair gets longer.
Tidy the lines every few days and trim the length weekly. Check the rounded corners during each trim so you don't gradually square them off again.
If the angular outline still doesn't appeal, compare the shapes in the diamond-face beard guide. Use the lower-face outline as your comparison point.
Questions people ask
