I use my iPhone to take a photo, then overlay a grid to use as a guide to a chalk drawing of the photo. This process can be done on a computer, for example using photoshop, however, being able to use the iPhone potentially saves extra steps, time and is more portable.
The following steps describe the process I have experimented with to create grid overlays on the iPhone, which are printed to our hp color printer using an app for wireless printing.
1. Take a Photo

The good news is FotoJet has made it easy, free and fun. A simple and free app for putting a grid on an existing photo. Grid size in terms of rows and columns can be set freely or based on presets. Line thickness can be set in pixels, line color can be. Creating a photo grid online is never been so easier.

This photo of a guitar player was taken at a local cafe one Saturday afternoon. Obviously, composition and lighting are important, but I didn’t feel I could ask him to move his speakers and chairs around to accomodate my artistic needs!
2. Open iPhone App to Edit Photo
There are several iPhone apps that allow you to overlay one image (e.g., a grid) on another image or photo.
Proportion Grid Creator Upload a photo, crop it to match the size of your canvas, and add grid lines. With the Proportion Grid Creator you can quickly place a drawing grid over your reference photo. After a few quick steps you'll have a great tool to get the perfect proportions for your next painting!
The program I currently use is Sketchbook Mobile Express, made by Autodesk. They offer a free version with up to 3 layers.
3. Add a Grid Layer
Touching the small, round tool icon at the bottom of the SketchBook Mobile window brings up a set of icons. Touching the Layers Editor icon (about “7 o’clock”) brings up a screen where “+” creates a new layer.
Then, touching the icon to the right of the “+” allows you to select an image (in this case, a grid) from your photo library. I created a grid by using Photoshop Elements to draw the grid pattern, added the image to iPhoto, then synched to my iPhone. You can also email the grid file to your iPhone then save to a photo album.
You can create your own grid with Adobe Elements (or a similar program), or download a copy of the grid I am using (right-click on grid image to the left). I used Elements, and “Saved for Web” as a GIF with transparency.
You can also draw a grid by hand and take a photo of it, however, you will need to reduce its opacity (within the iPhone app) so the image layer shows through.
The image to the right shows the photo with the grid overlay. If you have an HP wireless printer and HP printing app, you can print the image directly from your iPhone (however, the app only seems to print in a reduced size). Or, email the photo to a computer for printing full-size to use as a guide for drawing. It may be helpful to also print a version of the photo without the lines, as sometimes the lines may obscure important details.
Lacking a printer, you can always just use the iPhone image as a guide.
4. Draw a Grid on your Paper or Canvas
Use a ruler and pencil (or chalk line, if working on a chalk street painting) to lay out a grid that corresponds to the grid overlayed on your photo. In the example, I only drew the major lines, to produce a 4 x 6 grid.
I Want To Grid My Photo
You can also draw the sub-lines if you are working with a detailed image, however, it is more work to add and subsequently erase the extra lines. Working with fewer lines requires that you pay more attention to the spaces and relationships between lines, so you are less likely to get too involved in a technical tracing exercise.
You will have to scale the distance between the lines depending on the size of your canvas. For example, because my pad of paper was 11 inches wide, I measured a distance of 2.5 inches between each of the four vertical lines to span 10 inches, compared to the 8 inch width of the printed image. Similarly, the six horizontal lines were measured 2.5 inches apart, so they extended the length of the 15 inch tall paper. Keep the distances between all lines the same, or the proportions will be distorted.
If you are working on a chalk street painting, you may be measuring a distance of 12 inches or more between the lines.
5. Sketch Image
Using the photo with the grid overlay as a guide, sketch the image onto the matching gridlines on your paper or canvas. The major and minor lines help you to check that your sketch matches the proportions of the original photo. Your lines should cross in the locations on the gridlines as the corresponding lines on the original photo.
After you are satisfied with the drawing, erase the gridlines.
6. Complete Your Art
Using pastel chalk over the sketch, I find that starting with very light layers helps to retain the sketch as a guide for a longer period. Once I am happy with the shapes and shading, then I feel more comfortable adding layers that eventually obscure the original sketch.
When we spotted Alex’s giant photo grid (made with our Square Prints!) on Instagram we flipped out over how good it looked – and regrammed it so fast.
We got a lot of questions along the lines of “how did he do that?” So, we’re here to answer.
We’ve gathered three, yup three, ways to turn one photo you love into an amazing photo grid.
And, if you want to try it out yourself, remember our 4” Square Prints are always free (yup, $0.00 + shipping). You can upgrade to a set of 5.5” prints for just $5 – and make an extra big grid.
The Quickest Way to Make a Little Grid
There are apps made to help you split up a photo, so you can post pieces to Instagram to make one big photo show up when you look at your profile (neat, huh?).
We used Griddy to divide up a shot into a 3 x 4 grid. The only downside is that you can only make a grid three photos wide, since it’s designed to go on Instagram.

Let The Internet Split It Up for You
Rasterbator.net is a great site for splitting up your photo. Unfortunately, it doesn’t work so well on your phone, so you’re going to need to grab a compy for this one.
Upload the photo of your choice and change “Paper Setting” to “Custom.”
Set the dimensions to 200mm x 200mm. This will make the square photo files that are generated, plenty big enough to print on our 4″ or 5.5″ squares.
Uncheck the “Add margin” option – our Square Prints already have a border, so you don’t want to double up.
Drawing Grid Maker
Adjust the “Output Size” till the preview is split up just how you like it. Click on through the next few screens and your photo will be split up as if by magic (or computer … same thing?)
One slight hitch here is that Rasterbator spits out your newly split squares as a PDF, so you’ll need to export the pages as jpgs, or use an online converter (like this one) before you place your order.
Photoshop It Up (Just Like Alex)
Alex used Photoshop, so if you’ve got access to the Creative Cloud, you can can do the splitting yourself.
Grab that “Slice” tool (right click on crop to find it). Set it to fixed aspect ratio (1:1).
We put the first slice over the part of the photo that we definitely wanted intact (our pal Darby there in the middle), then lined up more slices in a grid around it.
Finally, “Save for Web” and you’ll get a folder full of jpegs just waiting to be ordered up as Square Prints.
Try it Out for Free
Grab a set of 20, 4″ Square Prints for free, or just $5 for a set of 5.5” squares – just pitch in for shipping.
