I started at age 8 with an 8.5 ft glass rod. Didn’t have any trouble handling it and I never broke it. Still use that rod exclusively for fly fishing. For the vast majority of kids, I’d choose a rod composed of a material and rated at a particular weight that is more forgiving when the inevitable whack on a tree limb occurs.I wouldn't go any shorter than an 8ft. Longer rods cast better. There could be some frustration trying to learn on a shorter rod. Rods are much lighter than when I learned to cast. he could handle a 9ft without struggling. IMHO Also, he might really like it and you never know what the financial situation will be when he discovers smallies or anything larger than a 2lb trout.
