Marker Based Augmented Reality means technology that can present digital content in the real world based on markers. The weakness of the research on developing Marker Based Augmented Reality applications found is using small digital content. Weakness is caused by the area of view of Augmented Reality cameras is limited by the placement of markers that are affordable to the user's hand. The fundamental contribution and advantage of this study to modifying the Grid method become a vertex marker for reproducing a large digital object accurately and can be reached by hand when displayed. Finally, the accuracy testing revealed continous of pieces of digital objects that showed by vertex markers are accurate.
