1. Choosing the length: Match with face shape and height

• Chin-length (short curly bob):
   
  It ends right at the chin, which is ideal for people with oval, heart-shaped, or long faces. For long faces, this length shortens the visual length of the face; for heart-shaped faces, it fills the hollow area of the jawline, making the face contour softer. It’s also a great choice for petite people (under 158cm), as it won’t press down the height and can create a "head-to-body ratio" that looks more delicate.
• Jaw-length (mid curly bob):
   
  Falling to the jawline, this is the most versatile length, suiting almost all face shapes—especially square faces and round faces. For square faces, the curly texture softens the sharp jawline; for round faces, it stretches the face vertically (paired with side bangs for better effect). It’s suitable for people of medium height (158-168cm), as it can highlight the neck line and add a sense of elegance.
• Shoulder-grazing length (long curly bob):
   
  Ending 1-2cm above the shoulders, it’s perfect for people with narrow faces, small facial features, or tall statures (over 168cm). It adds volume to the lower part of the face for narrow faces, making facial features look more three-dimensional; for tall people, it avoids the "top-heavy" feeling of short bobs and maintains a sense of balance. Avoid this length if you have a round face with a short neck, as it may make the face look rounder.

2. Choosing the curl pattern: Based on facial features and daily scenarios

• Loose waves (large curls):
   
  The curls are soft and natural, with a large curvature (similar to the effect of a 32mm curling iron). This curl pattern is low-key and elegant, suitable for daily commuting, office, or casual outings. It’s friendly to people with prominent cheekbones: the soft large curls can cover the protruding parts of the cheekbones, making the face look smoother. It’s also a good choice for those who want a "natural without looking like wearing a wig" effect, as the large curls are close to the texture of naturally permed hair.
• Spiral curls (medium-small curls/wool curls):
   
  The curls are tight and elastic, with a small curvature (similar to 22-28mm curling iron effect). This style is full of personality and vitality, suitable for daily leisure, parties, or street-style looks. It’s ideal for people with flat cheeks or thin faces: the dense curls add volume to the cheek area, making the face look plumper and more energetic. Note that this curl pattern has strong visual expansion, so people with round faces should choose it carefully (if you really like it, match it with thin side bangs to reduce the "roundness").
• Textured loose curls (water ripples):
   
  Between large waves and spiral curls, the curls are irregular and layered, with a lazy and casual texture. It suits all face shapes, especially people with small facial features, as it can add layering to the hair and make the facial features look more vivid. It’s a versatile choice for both daily wear and light makeup looks, and it’s not easy to look messy even after long-term wear.

3. Additional tips for matching with bangs

• If you choose short chin-length curly bob, match it with thick straight bangs or air bangs to highlight the cute and playful style; avoid overly long side bangs, which will make the upper and lower parts of the face look unbalanced.
• If you choose mid jaw-length curly bob, oblique bangs or broken bangs are the best match—they can stretch the face line and echo the soft curl of the bob.
• If you choose long shoulder-grazing curly bob, thin air bangs or side-swept bangs are more suitable; thick 齐刘海 may make the long bob look heavy and suppress the sense of lightness.
