Abstract Gridding dimension has been carried out in order to measure and illustrate the complexity and self‐similarity of coding sequences from human genes. The fractal dimensions of DNA sequences, including exons, coding sequences and some random ones have been studied in this work. The 60 genes from human genome were the choice as samples, and the results show that the gridding dimension of the whole coding sequences is smaller than that of every exon. The conclusion was corroborated by random sequences, and by combination of fractal theory with Fourier power spectrum, it speculated that gene with fewer exons could embody more information while it was contrary for gene with more exons and some information might be stored in introns generally. These results are helpful to understand the complexity of DNA sequences.
