Grid Method for Sketching
Grid method for Sketching or drawing is the simplest method for the Beginners to start with. Anybody who is interested in Art or Drawing or sketching who wants to draw portraits or any sketch can easily learn with the Grid Technique. It is a fair method to reproduce or to enlarge an image in sketch.
How does this works?
Grid method as the name suggests involves drawing grids (square boxes) over the reference photograph. Once done then you need to draw the same Grids on the drawing medium viz. Sheet, Canvas etc. You can scale the Grids if you need an enlarge drawing or sketch than the reference photograph. For example if you have drawn grids on reference photograph of 1x1 cm2 each and you want to scale it then you can draw the girds on the drawing sheet by scaling it to double (or at required scale) as 2x2 cm2 each. Mark the numbering on both horizontal and vertical boxes on both the photograph as well as on the sheet. Once done with drawing grids on Sheet or paper then you need to be focussed upon one square at a time and draw the outline first for the sketch. Once finished with the complete outline need to proceed with shading and detailing by focussing upon box by box. You can erase the grids once done with complete outlines of the sketch.
What do you need to draw Grid
Grid is simply a combination of successive square boxes in horizontal and vertical direction of the same dimension. In order to draw the Grid you need a Ruler and Pencil. You can take the printout of the reference photograph to make grids on it. And for drawing sheet you can use any good quality drawing paper. Mechanical Pencils would work very fine for drawing grids. Mechanical pencils of 0.3 mm or 0.5 mm point tip should be used for gridlines. Because we need very fine grids to copy the outlines from reference photograph and we need not it further when we done with outline so it must be easy to be erased as well. Also thin lines drawn with Mechanical Pencils on the reference photograph would not destroy the details. Ensure to draw these lines very lightly on the surface.
You can also use any Grid making software to draw the gridlines on the reference photograph if you do not want to take the printout. But it will be good to take the printout and then you draw the gridlines on it.
Just make sure to maintain the ratio while making the gridlines to avoid any distortion for the outlines and details. Grids should be in square shape only and of equal dimension.
Let’s take an example as below. Consider the photograph as the reference pic.
We need to draw the Grid on this photograph. Take the printout or use any software or app to draw the gridlines. In this picture gridlines are drawn with the help of app and of 1x1 cm2 dimension. Marking done as well.
You are done with reference pic. Now draw the grid on the Sheet with ruler and pencil. If you want to scale the sketch you can do that while making grids on the sheet but make sure to maintain the ratio from the reference picture. If you want to draw at the same scale then you can straightforward start with the exact dimensions used for reference picture. Below can be drawn on sheet.
Below is drawn on the A3 sheet with scaling of 1.5 from the reference pic. The grid drawn is of 1.5x1.5 cm2 block each.
Once done with the scaling and outline then we have to work on the sketch with Shading and Detailing. We will discuss about shading techniques & detailing in detail of the artwork in forthcoming articles. To proceed with shading just be focussed on the reference pic and draw block by block. Start shading from eyes and eyebrows (or you can start from any portion you are convenient with). Have a look at some of the progress snaps of this sketch.
Progress gradually and do shading layer by layer focussing on the reference picture. Apply dark shades wherever you see darker areas. Shade on face followed by hairs and then shade the clothes. The approach is simple you have to work from top to down so that the pencil shading (graphite) may not spread on the paper with your hands touch.
Once done with layer by layer shading add details by referring to the photograph. Gradually you will reach to the final results.
