When it comes to matching paint, the size of the paint chip matters. While it is possible to match paint from a chip as small as a dime, a quarter-sized chip is ideal. This ensures enough paint for a colour-matching scanner, like a spectrophotometer, to accurately identify the paint colour. To get a chip of this size, you can use a utility knife to cut a small square from an inconspicuous area of the wall, such as behind furniture or an outlet. Once you have your paint chip, you can take it to a paint store to find your match.

What You'll Learn
Paint chip size for matching: quarter-sized
When it comes to matching paint, a quarter-sized chip is considered a good size to aim for. This is because it provides enough paint for a colour-matching scanner to accurately identify the shade.
While a smaller sample may be adequate, a quarter-sized chip is a good benchmark. This is especially true if you are trying to match an older paint colour, as the paint may have faded or changed over time. In addition, if you are attempting to match a paint colour for a car, a quarter-sized chip is a realistic size to aim for, as it is often large enough to be repaired with a touch-up kit, without needing to respray the entire panel.
It is worth noting that the finish of the paint is also important when matching. A paint chip from an area that is not in direct sunlight will be more accurate, as sun exposure can cause fading. In addition, if you are trying to match a specific paint finish, such as high-gloss, it is important to ensure that the paint chip you provide is from a section with the same finish.
To obtain a quarter-sized paint chip, you can carefully cut a small piece from an inconspicuous area, such as behind furniture or an outlet cover. This will ensure that the paint chip is large enough for accurate colour matching, without causing noticeable damage to the painted surface.
By following these guidelines, you can ensure that you have a paint chip that is the right size and quality for accurate colour matching.

Paint chips from hidden areas
To repair paint chips on a wall, you will need basic supplies such as sandpaper, patching and repair supplies, including a paint scraper, wire brush, sandpaper, and a primer. First, remove any furniture from the area or cover it with a tarp to protect it. Then, remove the largest chips first, working your way down to the tiny paint flakes, being careful not to damage the wall. After removing the paint chips, fill in any shallow parts or holes to make them flush with the surface and let the wall dry for 24 hours or as directed. If you need to speed up the process, you can use a hairdryer on a low setting.
Once the wall is dry, smooth the patch with fine-grit sandpaper, ranging from 180 to 220 grit. If you want to check the smoothness, you can hold a piece of paper over the patch and lightly colour it with a crayon. If the wall has a textured surface, you may need to use a small artist's paintbrush to create tiny indents in the spackle to match the wall's texture. After sanding, vacuum up any dust and wipe the area with a damp sponge to remove any sanding grit. Then, apply a primer to the repaired areas, which will help the paint adhere to the wall and seal out moisture.
When matching paint colours, you can bring a paint chip to a store, and they will use a machine to analyse the colour and provide a custom formula for a colour match. The paint chip should be reasonably sized and have a consistent colour and finish—nothing porous, mirrored, or high-gloss. If the object is too large to bring into the store, you can also provide a photo of the colour, although matching the sheen may be more difficult. It is important to ensure that the paint chip is from an area that does not receive direct sunlight, as sunlight can cause fading, resulting in a sunbleached version of the colour.
For car paint chips, it is important to repair them as soon as possible to prevent rust and paint peeling. You can buy a small bottle of colour-matched touch-up paint and a small can of auto primer to perform the repair. First, wash the area with soap and water and dry it with a microfiber towel. Then, clean the chip and surrounding area with a detergent solution. Finally, apply the touch-up paint and protect the new paint and surrounding areas with a coat of car wax.

Outlet cover paint chip hacks
Painting outlet covers can be a great way to give your home a fresh look without breaking the bank. However, it can be frustrating when the paint starts to chip or peel. Here are some tips and tricks to help you avoid those issues and achieve a professional-looking finish:
Prepare the Surface:
Before painting, it's essential to clean and prepare the outlet covers. Start by unscrewing and removing the covers from the wall. Clean them with a simple solution of warm water and dish soap, ensuring they are free of dust, grease, or any paint stains from previous coats. Let them dry completely. If there are stubborn paint stains or a full layer of paint, use rubbing alcohol to remove it, but avoid paint thinner as it might melt the plastic.
Sand and Prime:
Lightly sand the surface of the covers with an abrasive sponge or sanding paper (220 grit). This will create a rough surface for the paint to adhere to. Next, apply a primer to ensure the paint job lasts. Use an oil-based primer, especially if you're working with plastic covers, as it works best on non-porous surfaces. Spray or apply the primer in a single, thin, and even layer. Allow it to dry completely, and then lightly sand again to smooth out the surface.
Paint Application:
When it comes to painting, opt for a small foam roller or a high-quality paintbrush. Start by applying a light coat of paint, using the same paint you used for the wall to ensure an exact colour match. Allow the first coat to dry completely before deciding if another layer is needed. If you're going for a second coat, lightly sand the cover again to create a smooth base. Continue this process until you achieve the desired colour match. Don't forget to paint the heads of the nails or screws as well!
Protective Finish and Reinstallation:
Before reinstalling the covers, finish the paint job with a clear protective coat, which can be matte or shiny depending on your preference. Allow the paint to cure for a week or two before reinstalling the covers. Carefully screw the covers back in place and test that everything is functioning properly. Be extra gentle with the covers for the next couple of weeks to avoid scratching or chipping the fresh paint.
Additional Tips:
- If you're painting metal covers, you can skip the sanding and scuffing process. Simply clean them, apply the primer, and follow up with paint.
- To remove rust from metal covers, soak them in vinegar for five hours or use rust-neutralizing products.
- Always prioritize safety when working with electrical outlets. Turn off the power at its source before starting the painting process, and double-check with a non-contact voltage tester.
- Use painter's tape to protect the surrounding areas from paint splatters or spills for a clean, professional finish.
- Apply paint in thin layers with a small brush to avoid overloading the outlet and interfering with electrical components.

Computerized color-matching
Computerized colour-matching technology has been developed to help with paint matching. This technology uses a spectrophotometer to analyse paint chips and match them to the closest colour in a brand's selection. Spectrophotometers use interference filters to ensure only the colour of the sample reaches the filters, with all other wavelengths reflected away. This increases accuracy as absorption can interfere with readings. The correct wavelength is then sent to computer software that formulates the exact amount of pigment required to make the match.
Handheld spectrophotometers are available for purchase, ranging in cost from $300 to $1,000. These smaller units are less sophisticated than their countertop counterparts and will find the closest match to existing paint colours, rather than formulating an exact match. Some paint manufacturers have handheld units that specifically match their selection of paints, while other units offer a full range of 13,000 colours from leading paint manufacturers.
To use a spectrophotometer, a paint chip sample is required. This sample should be at least one square inch in size and have a consistent colour and finish. It should not be porous, mirrored, or high-gloss. The sample can be taken from an area that is less visible, such as behind furniture or an outlet cover, to minimise the visibility of the missing paint.
Computerized colour-matching systems, such as Sher-Color by Sherwin-Williams, provide quick and accurate colour matches in minutes. The Sher-Color "eye" analyses the sample and provides a custom formula for a more accurate colour match using Sherwin-Williams paint, as well as formulas for the closest colours available in their palette.

DIY paint chip methods
A paint chip, or paint sample, is a small piece of paint that can be used to match a colour when painting a wall. Paint chips are usually obtained for free from home improvement stores, but can also be cut from an existing wall.
To get a paint chip from an existing wall, you can use the method demonstrated by TikTok user Cara Newhart. In the video, Newhart removes an outlet cover and cuts off a piece of the wall behind it. She then places the outlet cover back on the wall and uses the small paint chip sample for colour matching. It is recommended that the paint chip is at least one square inch in size, and that it is taken from an area of the room that is less visible, such as behind furniture.
Once you have obtained a paint chip, you can take it to your local hardware store to use a colour-matching scanner and find the matching paint.
Paint chips can also be used for various DIY crafts and projects, such as:
- Bookmarks
- Jewellery
- Storage
- Party decorations
- Lampshades
- Games
- Wall art
- Coasters
- Ornaments
- Cards

Frequently asked questions
The recommended size for a paint chip is at least one square inch. However, some sources suggest that a smaller chip, around the size of a dime or a quarter, is sufficient.
It is best to take the paint chip from an area that is less visible, such as behind furniture or near an outlet cover. This ensures that any colour variation due to sunlight exposure is minimised.
If you are unable to obtain a large enough paint chip, some stores offer colour matching from images. You can bring in a photo of the colour you want, and their experts will find the closest match. However, matching the sheen of the paint may be more difficult with this method.
