A Legit training method to improve your drawing and observational skills
What is the Grid Method?
As I mentioned in Lesson 3 and 5, I don’t recommend tracing artwork.
Tracing can give you instant satisfaction, but in the long run, it teaches very little about observation, proportion, and drawing skills.
However, many beginners think:
“How can I draw accurate proportions when I don’t even know where to start?”
That’s where the Grid Method becomes extremely useful.
The grid method is one of the easiest and most effective ways to improve accuracy in drawing while still training your eyes and observational skills. It allows you to reproduce, enlarge, or shrink an image by breaking it down into smaller, manageable sections.
Unlike tracing, the grid method still requires you to carefully observe shapes, angles, edges, and proportions. You are actively drawing and analyzing what you see instead of simply copying lines.
A Brief History of the Grid Method
The grid method has been used for centuries by artists and designers. Its origins can be traced back to ancient Egypt, where artists used grid systems to maintain accurate proportions in murals and sculptures.
Many master artists, including Leonardo da Vinci, also used measurement systems and proportional guides in their work. Before photography existed, artists relied heavily on these techniques to accurately transfer images onto larger surfaces such as walls, canvases, and ceilings.
Even today, many professional artists still use grid systems when creating large-scale paintings, murals, portraits, or realistic drawings. Below is the actual tool that I used when drawing from observation in art school. The grid method works on the exact same principle — instead of using a physical measuring scale like this, you create matching grids on both your reference image and your drawing paper to help measure proportions and placement accurately.
Why the Grid Method Works
One of the biggest challenges beginners face is trying to draw the whole image at once.
The grid method solves this problem by dividing the reference image into smaller sections. Instead of worrying about the entire drawing, you only focus on one square at a time.
This makes complex subjects feel much simpler and helps you:
Improve proportion accuracy
Understand placement and spacing
Observe angles more carefully
Train your hand-eye coordination
Reduce intimidation when drawing difficult subjects
Build confidence in sketching
It also helps beginners learn how to “see like an artist” by focusing on abstract shapes rather than symbolic shortcuts.
How to Use the Grid Method
Using the grid method is actually very simple.
Step 1 — Prepare Your Reference Image
You can either:
Print your reference photo (preferable)
Use a digital image on your phone, tablet, or computer
Then draw a grid over the image using evenly spaced squares.
If you work digitally, you can also use apps such as:
Drawing Grid Maker
Grid Drawing App
Procreate grid tools
Photoshop guides
Step 2 — Create the Same Grid on Your Paper
Draw the exact same number of squares on your drawing paper using a ruler.
The ratio must stay exactly the same.
For example:
If your reference image uses a 4 × 4 grid,
Your drawing paper must also use a 4 × 4 grid.
You can enlarge or reduce the size as long as the proportions remain identical.
For example:
1-inch squares on the reference
2-inch squares on the drawing paper
This enlarges the image while keeping proportions accurate.
Below is a great video that demonstrates every step of the grid method in action. Watch carefully, try it yourself, and adapt the technique to your own drawings.
TIPS
Keep the Grid Lines Light
This is very important.
Draw your grid lines as lightly as possible so they are easy to erase later. The same applies to your initial sketch lines.
Heavy grid lines can become difficult to remove and may damage the paper surface after repeated erasing.
Square Grids vs Rectangular Grids
The most important rule is consistency.
Your grids must maintain the exact same ratio between the reference and your drawing surface.
Although rectangular grids can work, square grids are usually much easier to manage because they:
- simplify measurement
- make angles easier to judge
- reduce distortion mistakes
- help beginners stay organized
For most students, perfect squares are the safest and easiest option.
Focus on One Square at a Time
This is the secret that makes the grid method effective.
When transferring the image:
- Ignore the entire picture temporarily
- Focus only on one square
- Observe where lines enter and exit the edges
- Compare distances carefully
- Look for shapes instead of “objects”
For example, instead of thinking:
“I’m drawing an eye.”
Think:
“There is a curved line starting near the top-left corner and ending halfway down the square.”
This approach dramatically improves observational skills.
Repeat this process square by square until the entire image is complete.
Choosing the Right Number of Grids
The number of grid squares affects accuracy.
Larger Grids (4 × 4 or 5 × 5)
Good for:
- Beginners
- Simple subjects
- Quick sketches
Smaller Grids (8 × 8 or more)
Good for:
- Realistic portraits
- Detailed drawings
- Complex compositions
Smaller squares increase accuracy because each section contains less information to analyze.
However, too many grids can feel overwhelming, so try different sizes and find what works best for you.
Common Mistakes Beginners Make
- Drawing Too Dark Too Early
Keep your sketch light until the proportions are correct.
- Ignoring the Edges of the Squares
The edges act like measuring points. Pay close attention to where lines touch the borders.
- Focusing on Details Too Soon Start with large shapes first before drawing eyelashes, wrinkles, or textures.
- Distorting the Grid Ratio
Even slightly uneven grids can throw off the entire drawing.
Does Using the Grid Method Count as Cheating?
The answer is No!
The grid method is a learning method — just like perspective guides, gesture drawing, or anatomy studies.
Many professional artists use grids for:
- Portrait commissions
- Murals
- Large canvases
- Complex compositions
The goal is not to rely on it forever, but to use it as training for your observational skills and proportional understanding.
Over time, you’ll naturally begin estimating proportions more accurately without needing grids as much :)
Final Thoughts
The grid method is one of the best techniques for beginners who struggle with proportions and placement. It breaks difficult drawings into manageable steps and teaches you how to observe more carefully.
Most importantly, it helps you build confidence while still developing real drawing skills — unlike tracing, which often skips the learning process.
It may feel a little slow at first, you’ll realize how simple and powerful it can be once you try it.
