Kindly send picture. Front two teeth are always bigger than other teeth. No treatment can reduce teeth size because if done so there are chances of sensitivity. Also if the teeth are trimmed then there will be gaps in teeth.

If the size is wider and bigger right from the time the tooth erupted, then you can go for crowns, if needed better do RCT and then crowns. This is the best option. Veneers might cause sensitivity issues later. If the size is bigger recently, then it might be due to periodontal problem, please do professional cleaning and go for periodontal therapy. Braces can intrude your tooth to some extent. This is also a good option( if your periodontal status supports and also if you wish)

Other option is Veeners on front 4-6 teeth. But can’t say it with surety till I see you clinically
