Choosing the right diamond painting size is one of the most important decisions you can make before starting a project.
A larger diamond painting generally gives an image more room for detail, while a smaller painting can be quicker and easier to complete. The best size depends on the image you want to create, how much detail it contains and how much time you want to spend on your project.
Whether you are buying your first diamond painting or choosing a size for a custom photograph, this guide will help you understand how diamond painting sizes work and how to choose the right one.
Why Does Diamond Painting Size Matter?
The size of a diamond painting affects how much detail can be represented in the finished artwork.
Imagine trying to reproduce a detailed photograph of a person’s face in a very small space. There simply isn’t enough room for every small feature to be represented clearly.
Increasing the size gives the image more space, allowing individual details to be represented using more drills.
This is particularly important for:
- Portraits
- Pet photographs
- Faces
- Animals
- Landscapes with fine detail
- Images containing small objects
- Photographs with complicated backgrounds
A simple image with large areas of colour may work well at a smaller size, while a highly detailed photograph may need a much larger painting.
What Does the Diamond Painting Size Mean?
One important thing to check when ordering a diamond painting is what measurement the listed size refers to.
At Diamond Art SA, the size shown for our paintings refers to the actual image or drill area, rather than the overall canvas.
This means the physical canvas will be larger than the stated image size because additional canvas surrounds the image area.
Always check the individual product information before ordering, as specifications can vary between products.
Small Diamond Paintings
Smaller diamond paintings can be a good choice for beginners or anyone looking for a project that doesn’t require a large amount of time or workspace.
They can also work particularly well for:
- Simple designs
- Small decorative pictures
- Children’s projects
- Beginner projects
- Small gifts
- Designs with less fine detail
If you are new to diamond painting and aren’t sure whether you will enjoy the hobby, starting with a smaller project can be a great way to learn the basic technique.

Medium-Sized Diamond Paintings
Medium-sized paintings offer a balance between detail and completion time.
They provide more space for an image to develop than a small painting without requiring the same amount of time and workspace as a very large project.
Medium sizes can work well for:
- Animals
- Flowers
- Landscapes
- Decorative artwork
- More detailed designs
- Intermediate diamond painters
The ideal size will still depend on the particular image.
Two images of exactly the same size can require very different amounts of detail depending on the design.

Large Diamond Paintings
Large diamond paintings give an image significantly more space for detail.
They are particularly useful when you want to reproduce:
- Faces
- Family portraits
- Pet photographs
- Highly detailed animals
- Complex landscapes
- Detailed artwork
- Large statement pieces
A large painting does take more time to complete, but the additional space can make a significant difference to the appearance of a detailed image.
If you have a photograph containing several people or important facial details, choosing a larger size is often worth considering.

Choosing the Right Size for a Custom Diamond Painting
Size becomes especially important when you are creating a diamond painting from your own photograph.
A photograph contains a huge amount of information and detail. When it is converted into diamond art, the image has to be represented using a limited number of coloured resin drills.
A larger canvas gives those details more room.
For custom photographs, Diamond Art SA recommends starting from approximately 50 × 70 cm or larger when good detail is important.
This is particularly relevant for photographs containing:
- People
- Faces
- Pets
- Multiple subjects
- Fine details
- Detailed backgrounds
If you are unsure which size is suitable for your photograph, it is a good idea to ask before ordering.

hy Small Photos Can Be Difficult to Turn Into Diamond Paintings
A common mistake is choosing a very small size simply because the original photograph looks clear on a phone or computer screen.
A photograph viewed on a screen can contain far more information than a small diamond painting can reproduce.
For example, a photograph of a person may clearly show their face when viewed on a large screen. If that same photograph is reduced to a small diamond painting, there may not be enough space for the eyes, nose, mouth and other features to be represented clearly.
This is why the size of the finished diamond painting matters just as much as the quality of the original photograph.
Does a Bigger Diamond Painting Always Look Better?
Not necessarily.
A larger size isn’t automatically better for every image.
If the original design is simple, increasing the size may not add much useful detail.
The goal is to choose a size that gives the image enough space to reproduce the important details without creating an unnecessarily large project.
The image itself should always be considered when choosing a size.
How to Choose a Diamond Painting Size for a Portrait
Portraits often benefit from larger sizes because faces contain many small details.
When choosing a size for a portrait, consider:
- How many people are in the photograph
- How large the faces are within the original photograph
- How much background is included
- Whether facial details are important
- How large you want the finished artwork to be
A close-up portrait with one person may require less overall canvas than a family photograph showing several people.
For a family photograph, a larger size can help ensure that each person’s face has enough space to be represented.
How to Choose a Size for a Pet Diamond Painting
Pet photographs can also benefit from additional size, particularly when you want the finished painting to show details such as:
- Eyes
- Fur
- Facial features
- Whiskers
- Nose
- Markings
A close-up photograph of one pet may work well at a smaller size than a photograph showing several animals or an animal in a detailed environment.
If you are considering a custom pet diamond painting, choosing a clear photograph and an appropriate size will give you the best starting point.

How Much Workspace Do You Need?
Remember that a large diamond painting doesn’t only require more time. It also requires more physical workspace.
Before ordering a large project, consider where you will work on it.
You may need space for:
- The canvas
- Drill containers
- Your tray
- Applicator
- Wax
- Additional tools
- A comfortable working area
If you don’t have a permanent craft area, a smaller painting may be easier to manage.
How Long Does a Diamond Painting Take?
The larger the painting, the more drills there are to place, so larger projects generally take longer to complete.
However, completion time also depends on:
- Your experience
- How quickly you work
- The number of colours
- The amount of detail
- How often you work on the project
- Whether you work for short or long sessions
A small project can be completed relatively quickly, while a large detailed painting can become a project you work on for weeks or even months.
There is no need to rush. One of the enjoyable things about diamond painting is being able to work at your own pace.
What Size Should a Beginner Choose?
If you have never tried diamond painting before, a smaller or medium-sized project can be a good place to start.
This allows you to learn:
- How to use the applicator
- How to use the wax
- How to read the symbols
- How to organise your drills
- How to protect the adhesive
- How you prefer to work
Once you’ve completed your first project, you may find yourself ready to take on a larger and more detailed design.
What Size Should I Choose for a Detailed Image?
If the image contains a lot of detail, consider choosing a larger size.
As a general guide:
Simple image → smaller size may work well
Moderately detailed image → medium size may be suitable
Highly detailed image → larger size is usually preferable
This isn’t a strict rule because every image is different.
If you are unsure, ask before ordering rather than guessing.

Final Tips for Choosing Your Diamond Painting Size

A larger painting can become a long-term project.
