How To Divide Lines: The Holy Grail for Great Drawing

Proportion and Dividing Lines

Dividing a Line Equally without a Ruler

Anyone who has picked up a pencil and wanted to make an accurate drawing knows the most important thing is proportions. That means you need to divide things up. Sometimes into several pieces. Now you can eye ball it but if you want to get to a better level of accuracy then you want to use a few simple techniques that will take your drawing to the next level. 

Dividing a Line Segment into 5 Equal Parts

Now I can use this method to divide it into any number of parts but for this exercise, it will divide it into five.

1.First, draw the line you need to divide using a straight edge. Of course, this could be freehand and I use this method freehand all the time.

2. Draw a line of “any angle”(it doesn’t matter the angle)  from point “A”. As pictured below

3. Using a compass or a divider or a ruler or even a mark of a random length. The length doesn’t matter. Now repeat that same length five times. All the marks must be of equal length! Below shows 5 marks of equal length on the line we will use to divide line AB.

4. From your last mark connect it to the end of your line AB at point B. This is very important! We have made a triangle. Then using lines parallel to the first one you just drew connect the points to the line â€œAB”. This should divide line AB into 5 equal parts.

5. Mark the points on line AB and erase your work lines. Now you have a line that is divided equally into 5 parts. Again I use this will hand sketching all the time.

Now the great part is you can do this by hand the same process and you will divide things much more accurately and quickly than you ever thought possible. Give it a try.
