Grid Drawing Mistakes and How to Fix Them
Grid drawing is reliable, but it is not automatic. Small setup errors can repeat across the page, and concentrating too narrowly on individual cells can weaken the final image. These common problems are easy to correct when you know what to check.

The Reference and Paper Have Different Proportions
If the outer rectangles do not share the same aspect ratio, matching cell counts will not preserve the image. A circle may become an oval and a face may appear wider or narrower than the reference.
Fix the crop before you start, or draw a correctly proportioned working area inside the paper. Compare width-to-height relationships rather than assuming the page edge is the drawing boundary.
The Grid Is Too Dense
Tiny cells can create the illusion of control while making it hard to see the subject. They also require more measuring, more labels, and more erasing. If every cell contains only a fragment with no recognizable direction, reduce the row and column count.
Use enough divisions to locate important changes, but leave enough space to observe curves and negative shapes. The grid should simplify the task rather than becoming the task.
Details Begin Before the Structure Is Correct
It is tempting to finish an eye, leaf, or window immediately. However, a beautifully rendered detail cannot repair a misplaced head or tilted building. Establish the outer contour and large internal shapes across the whole drawing first.
If you discover a major error, correct it while the lines are light. Waiting until after shading usually costs more time and can damage the surface through repeated erasing.
Contours Break at Grid Lines
When each cell is copied in isolation, curves may form small corners at the boundaries. Check the direction of the line before and after every crossing. Lightly redraw across several cells in one motion when the larger contour is clear.
Rotate the paper or step back to see whether the silhouette flows. The cell-level information and the whole-image gesture must agree.
The Finished Work Still Looks Like Squares
Patchy value changes happen when one cell is fully shaded before its neighbors. Build tones across larger connected areas, comparing shadows throughout the image. Edges and lighting should follow the subject, not the construction grid.
Erase exposed grid lines before applying very dark or permanent media. If a line cannot be removed completely, integrate it carefully into a value area without creating an artificial border.
