Does anyone know what is considered normal dimensions of a thyroid? I have Hashimoto's and went to the doctor with complaints of choking and neck tenderness/swelling. My ultrasound shows that the right lobe is 4.8 x 1.8 x 1.3 and the left lobe is 4.7 x 1.5 x 1.8.ep 06, 2005. The thyroid dimensions are at the upper limits of normal - I do 6-8 ultrasounds a day in the office and usually the measurements of normal thyroids are 4-4.8 x 1.0-1.8 x 0.8-1.6cm which is consistent with published dimensions.
