A cut generally needs stitches if it is deeper than about a quarter inch (0.25 inch or 6 mm) or longer than half an inch, or if it exposes fatty tissue, muscle, or bone. Other indications for stitches include cuts that are gaping open, jagged, bleeding heavily and not stopping after applying pressure for 10-15 minutes, or located on areas where healing is difficult like the face or over joints.
Key indicators that a cut requires stitches:
- Depth greater than 1/4 inch (6 mm)
- Length greater than 1/2 inch
- Exposure of fatty tissue, muscle, or bone
- The wound edges gape open and do not close easily with gentle pressure
- Heavy bleeding that does not stop after 10-15 minutes of direct pressure
- Jagged or irregular wound edges
- Location on face, joints, or areas stressed by movement
Additional considerations:
- Cuts that continue to bleed or spurt bright red blood may involve arteries and need urgent care
- Puncture wounds generally should be evaluated by a professional rather than stitched at home
- Stitches help reduce infection risk, promote proper healing, and minimize scarring
- It is best to get stitches within 6-8 hours of the injury for optimal healing
If a cut meets these criteria, it is advisable to seek medical attention for proper wound care and possible suturing.
