If you are after slight better spec and a few more features from a television then the mid-sized range is really with used 30"-39" TVs for sale.
Models in this sort of size range are perfectly suited to a range of rooms: smaller sized lounges and larger sized kitchens or bedrooms all foot the bill quite nicely for a second hand 30"-39" TV, making this size bracket pretty adaptable and versatile.
32" remains one of the most popular sizes of television and is best watched from a distance of around 1.5m away from the screen. This size is well suited to field of vision and great for most viewing purposes.

You'll find that most brands produce models within this size range that have a good range of features and a generally high specification. You certainly shouldn't think that this is only reserved for the extra large screen models.
