What to Look for in a Paint by Numbers Kit Before You Buy

Quick answer

Choose a paint by numbers kit by matching the canvas size to your available workspace, confirming the paint pots are enough for the number of colors, and checking that the brush count suits your hand size and patience. For kids, prioritize smaller canvases with fewer colors and thicker brushes. For adults, a larger canvas with more colors and a fine detail brush gives a more satisfying result.

Paint by numbers kits look similar on the shelf, but the differences that matter show up halfway through the project: a canvas that is too big for your table, paint that dries before you finish a section, or a brush that is too thick for the tiny numbered areas. This buying guide walks through the practical checks so you can pick a kit that fits your space, skill level, and the person who will actually paint it.

You do not need to be an artist to get a good result. You need a kit that matches your expectations. Below are the decision rules I use when comparing kits, including what to look for in the contents, how canvas size changes the experience, and when a simpler creative kit is a better choice than a traditional paint by numbers set.

Start with the canvas size and your workspace

Canvas size is the first thing to check because it determines how long the project takes and how much room you need. A small canvas, roughly the size of a sheet of paper, can be finished in one or two sittings and fits on a lap tray or a small desk. A medium canvas, closer to a poster, needs a table you can leave set up for several days. A large canvas can be rewarding for adults but demands more paint, more time, and a dedicated space where it will not be bumped.

Measure your table before you buy. If you only have a shared kitchen table, choose a canvas you can move easily or place on a drawing board. If you have a dedicated craft corner, a larger canvas is a good fit. Also check whether the kit includes a display option or if you will need to frame it yourself, since that affects the final size you need to store or hang.

• Small canvas: good for kids, travel, and first-time painters.
• Medium canvas: the most flexible choice for adults who want a weekend project.
• Large canvas: best for dedicated spaces and painters who enjoy long sessions.

Check what comes in the kit: paints, brushes, and guide

A complete kit should include the canvas, numbered paint pots, at least one brush, and a reference guide. The number of paint pots should match the number of colors on the canvas. If a kit has many tiny areas and only a few brushes, you may need to add a fine detail brush. If the paint pots are small, check whether the coverage is enough for the whole canvas, especially for colors used in large background areas.

Look for a printed guide or a numbered chart that is easy to read. Some kits include a separate practice sheet or a techniques guide, which helps if you are new to acrylic paint. If the kit does not list the brush sizes, treat that as a limitation: you may need to supply your own brushes for fine lines or broad fills. A kit that clearly states its contents saves you from buying extras later.

• Count the paint pots against the color numbers on the canvas.
• Check for a fine detail brush if the design has small areas.
• Look for a guide that shows the finished image and color map.

Match the kit to the painter: adults vs. kids

For kids, the best paint by numbers kit has a smaller canvas, fewer colors, and thicker brushes that are easy to grip. The numbered areas should be large enough that a child does not get frustrated trying to stay inside the lines. Acrylic paint markers can be a good alternative for young children because they are easier to control than a brush and dry quickly, which reduces smudging. If a child is under six, a scribble pad and washable markers may be a better starting point than a full paint by numbers kit.

For adults, the appeal is usually the opposite: more colors, smaller numbered sections, and a finer brush for detail. Adults can also handle a longer project and may prefer a canvas with a more complex image. If you are buying for a mixed-age group, choose two separate kits rather than one compromise kit, because the ideal brush size and canvas size for a five-year-old and a forty-year-old are very different.

• Kids: fewer colors, larger areas, thicker brushes, shorter sessions.
• Adults: more colors, finer detail, larger canvas, longer project.
• Mixed ages: buy separate kits to avoid frustration.

Consider the paint type and finish

Most paint by numbers kits use acrylic paint, which is water-based, dries quickly, and can be layered. Quick-drying paint is helpful for avoiding smudges, but it also means you should close the pot when you are not using it. If the kit includes metallic or specialty paints, check whether they need a different brush or a base coat. Some kits include paint markers instead of pots, which can be easier for children and for painting on the go.

If you want a glossy or shimmery finish, look for kits that include metallic paint markers or a sealant. If the kit does not mention a sealant, you can finish the canvas with a clear acrylic spray once it is completely dry. Always test on a small corner first. The paint type also affects cleanup: acrylic paint washes out of brushes with soap and water before it dries, but it can stain clothing, so wear an apron.

• Acrylic pots: classic, layerable, needs brush cleaning.
• Paint markers: easier for kids, good for travel, less messy.
• Metallic or specialty paints: check for extra instructions.

Decision rules for buying a paint by numbers kit

• Rule 1: Canvas size must fit your table and your patience: If you cannot leave a project out for a week, choose a small or medium canvas. If you have a dedicated space and enjoy long sessions, a large canvas is worth it. Measure your workspace before you buy.
• Rule 2: Count the colors and brushes against the design: A kit with many tiny numbered areas needs a fine detail brush. A kit with large areas needs enough paint for background colors. If the contents are not listed, assume you may need to add brushes. Check the contents list, not just the cover image.
• Rule 3: Match the kit to the painter's age and hand size: Kids need thicker brushes, fewer colors, and larger areas. Adults usually want finer detail and more colors. Do not buy one kit for a wide age range. Buy separate kits for kids and adults.
• Rule 4: Decide between paint pots, markers, and watercolor: Paint pots are classic but need cleaning. Paint markers are easier for kids and travel. Watercolor travel packs are best for sketching and portability, not for a full numbered canvas. Choose the medium that fits your mess tolerance and location.

What these kits actually include

• iHeartArt 12 Acrylic Paint Markers: 12 vibrant colors with waterproof paint that works on rocks, shells, sticks, leaves, ceramic, wood, glass, and more. If you want a paint by numbers alternative that travels well or works on surfaces beyond canvas, these markers cover many materials and are easy for kids to control.
• iHeartArt Travel Art Pack Watercolors + Fine Line Pen: Includes 16 watercolor cakes, a fine line pen, a water brush pen, a 25-page pad, and a Techniques Guide. A compact option for artists who want a portable set with a guide, useful if you are not ready for a full paint by numbers canvas or want a warm-up before a larger project.
• Metallic Paint Markers: 12 metallic paint markers with a fine point nib and a dot nib for shimmery art on rocks, shells, leaves, sticks, mugs, and more. These add a metallic finish to craft projects and can be used to accent a finished paint by numbers canvas or to decorate small objects when a full kit feels too big.
• iHeartArt JR Recycled Newsprint Scribble Pad: 60 sheets of recycled newsprint, 70 gsm, light grey, works with crayons, markers, colored pencils, and oil pastels. A low-cost way for young children to practice mark-making before they try a numbered canvas, and a good backup for kids who lose interest in structured kits.

Who should buy which kit

Best for

• Adults who want a focused, screen-free weekend project with a larger canvas and more colors.
• Kids ages 6–10 who enjoy structured art and can handle a small canvas with thicker brushes.
• Travelers or campers who want a portable art option like the iHeartArt Travel Art Pack Watercolors + Fine Line Pen.
• Parents looking for a low-mess alternative such as iHeartArt 12 Acrylic Paint Markers for young children.

Not for

• Children under 5 who still put small objects in their mouths or lack the fine motor control for numbered areas.
• Painters who want a complex, highly detailed image on a very large canvas and are not willing to buy extra fine brushes.
• Anyone who cannot leave a project set up for several days and needs a kit that can be finished in one short sitting.

The right paint by numbers kit is the one that fits your space, your patience, and the person holding the brush. Check the canvas size, count the colors and brushes, and choose a medium that matches your mess tolerance. If you are buying for a child, start smaller and simpler than you think you need. If you are buying for yourself, do not be afraid to go one size up and add a fine detail brush.
