Legible penmanship is important. However, young students have difficulty producing legible handwriting (Marr, Windsor, & Cermak, 2001). As legible handwriting is a benefit for both the students and the teachers in the classroom setting, this study examined if pencil size had an impact on preschool and kindergarten students' handwriting. The students used four different pencil sizes over a two-week period. The data showed pencil size did not impact handwriting legibility but there was a pencil size preference difference between preschool and kindergarten students, which may impact the yearly student supply lists.
