At the Yellow stage of LTA Youth, children are playing on a full size court with the same size balls the pros use. Having developed the skills from various stages of the LTA Youth pathway, children are now using a full-size racket. You'll see children continue to explore different game styles and learning how to play their way. It is worth noting, as children don't yet have the size and strength, they can't play at full capacity like adults but will develop this over time.
