Comece com uma grade de células 1x1. Escolha um ponto aleatório, mescle as células uma quantidade aleatória ou até que colide com um retângulo maior.
Isso fornecerá algo semelhante à imagem que você fornece.
Há um problema maior se você não quiser um número de células menores atuando como preenchimento entre suas células maiores. Uma história em quadrinhos, por exemplo, quer minimizar a quantidade de espaço morto e ter no máximo ~ 9 células. Você pode escolher alguns pontos, desenhar algumas linhas e chamá-las de células.
