How to Measure an RV for Replacement Decals and Graphics

When original RV graphics are cracked, faded, peeling, or no longer available from the manufacturer, reproducing them often starts with two things: good photographs and accurate measurements.

Measuring an RV decal is not always as simple as recording its width and height. Long stripes may curve across several feet of bodywork, graphics can cross compartment doors, and deteriorated vinyl may already have shrunk or lost pieces.

If you’re gathering information for replacement RV decals, documenting the graphics carefully before removal gives the person recreating them much more useful information to work with.

Don’t Remove the Old Graphics Yet

If the existing graphics are going to serve as references, photograph and measure them before removing them.

Even badly deteriorated decals can reveal useful information about:

• Original shape
• Approximate dimensions
• Color arrangement
• Position on the RV
• Relationship between separate graphic elements
• Curves and angles
• Alignment with doors and body lines

Once brittle vinyl has been scraped away, some of that information may be impossible to recover.

Start With Photos of the Entire RV

Before taking close-ups, step back.

Take clear photographs showing the complete:

✅ Driver side

✅ Passenger side

✅ Front

✅ Rear

These wider images establish context. They show how individual graphics work together as a complete design rather than treating each stripe as an isolated shape.

If only one graphic needs replacement, a wider photograph still helps establish its position relative to the rest of the RV.

Take Straight-On Photos Whenever Possible

Camera angle can distort the apparent shape of a graphic.

For example, photographing a long stripe from one end can make the far end appear much smaller than it really is. That perspective distortion makes the image less useful for reproduction.

Position yourself as directly in front of the graphic as practical.

For very long graphics, take several overlapping straight-on photographs instead of relying on one heavily angled picture.

A useful photo set might include:

1. One image showing the entire RV side.
2. One image showing the complete graphic.
3. Several closer images showing individual sections.
4. Detail photographs of complicated curves or intersections.
5. Photos showing where the graphic meets physical features of the RV.

More photographs aren’t automatically better. The goal is to capture useful references from appropriate angles.

Include a Known Measurement in Your Photos

A photograph provides shape information but doesn’t automatically establish scale.

Adding a visible measurement can make the image considerably more useful.

For example, you can position a measuring tape near the graphic while taking a photograph.

This helps establish the real-world size of features that might otherwise be difficult to judge from an image alone.

Measure the Overall Width and Height

Start with the basic dimensions.

For each graphic, record its approximate:

• Maximum width
• Maximum height

Measure the entire footprint of the graphic rather than only the thickest portion of a stripe.

For irregular shapes, maximum dimensions provide a useful starting point even though additional measurements may still be necessary.

Long RV Stripes Need More Than One Measurement

Consider a stripe that begins narrow, gradually becomes wider, curves upward, and then tapers again.

Simply saying the graphic is “12 feet long and 14 inches tall” doesn’t fully describe its shape.

Additional measurements can document:

✅ Width at the beginning

✅ Width at selected points along the stripe

✅ Maximum height

✅ Distance between curves

✅ Width near the end

These reference points make it easier to understand how the shape changes along its length.

Use RV Features as Reference Points

The RV itself provides useful landmarks.

Record how the graphics relate to fixed features such as:

• Compartment doors
• Windows
• Wheel openings
• Trim
• Panel seams
• Lights
• Handles
• Body lines

For example, instead of documenting only the size of a stripe, note that its lower edge passes a specific distance above a compartment door.

These relationships help reproduce the original placement.

Measure the Space Between Separate Graphics

Many RV graphic packages consist of several pieces that visually form one design.

The distance between those pieces matters.

If two sweeping stripes should run parallel but one replacement is installed several inches too high, the individual decal might be correctly sized while the complete design still looks wrong.

Record:

✅ Horizontal gaps

✅ Vertical gaps

✅ Overlapping visual relationships

✅ Alignment between separate pieces

This becomes particularly important when replacing only part of an existing graphic package.

What If Part of the Decal Is Missing?

A damaged decal doesn’t necessarily eliminate the possibility of reproduction.

Look elsewhere on the RV for additional references.

A similar graphic may appear:

• On the opposite side
• In another color
• On the rear
• In an old photograph of the RV

If one side remains intact, it may provide useful information about the damaged side.

However, don’t automatically assume that graphics on opposite sides are exact mirrored copies. Verify the design before relying on that assumption.

Photograph the Colors Before Removal

Color can be difficult to document accurately because cameras, lighting, screens, printing, and years of environmental exposure can all affect how a color appears.

Still, photographs provide valuable references.

For better results:

• Photograph in neutral daylight when practical.
• Avoid strong reflections.
• Take both wide and close-up images.
• Photograph multiple sections of the same color.
• Avoid relying on heavily shadowed photographs.

Remember that the visible color of an older decal may no longer represent how it looked when new.

Decide Whether You Want to Match the Current or Original Appearance

This decision can influence reproduction.

Suppose an originally dark red stripe has faded significantly over many years.

There are two different objectives:

Reproduce the original appearance

The new decal aims to represent the original design and color as closely as practical.

Blend with existing aged graphics

The replacement aims to look visually appropriate beside graphics that remain on the RV.

If you’re replacing the entire graphic package, restoring the intended colors may make sense. If you’re replacing one piece among numerous aged graphics, matching the surrounding appearance may become more important.

There is no universal answer.

Don’t Assume the Existing Vinyl Is Still Its Original Size

Old vinyl can change as it ages.

A deteriorated graphic may have:

• Shrunk
• Split
• Lost sections
• Pulled away from its original edges

Therefore, measuring the remaining vinyl alone may not always reveal the exact original dimensions.

Look for other clues.

Sometimes the previous footprint is visible around the old graphic, particularly where environmental exposure has affected the surrounding surface differently.

Photographs of the RV from earlier in its life may also provide additional reference information.

Label Your Measurements

A page filled with numbers becomes surprisingly difficult to interpret later.

Instead of recording:

94″, 16″, 11″, 7″

write:

Passenger side upper blue stripe
Overall length: approximately 94″
Maximum height: approximately 16″
Width near front: approximately 11″
Width near rear: approximately 7″

If there are many graphics, assign each one a simple number.

For example:

• DS-1 = driver-side upper stripe
• DS-2 = driver-side lower stripe
• PS-1 = passenger-side upper stripe

The exact naming system doesn’t matter as long as the photographs and measurements can be matched easily.

Common Measuring Mistakes to Avoid

Measuring only the visible undamaged section

If part of the graphic is missing, the remaining piece may not represent its original dimensions.

Taking only angled photographs

Perspective can substantially distort long graphics.

Removing everything first

This destroys potentially valuable reproduction references.

Measuring only width and height

Complex graphics often require intermediate measurements and placement references.

Forgetting where the graphic sits on the RV

Correct dimensions won’t help enough if the original placement isn’t documented.

Assuming both sides are identical

Some RV designs use mirrored graphics, while others contain meaningful differences.

Verify rather than assume.

Create a Simple RV Graphics Reference Package

You don’t need sophisticated equipment to organize useful information.

A practical reference package can contain:

1. Four overall photographs of the RV.
2. Straight-on photographs of each graphic.
3. Close-ups of complicated areas.
4. Overall dimensions.
5. Intermediate measurements for complex shapes.
6. Placement measurements relative to fixed RV features.
7. Year, manufacturer, and model of the RV.
8. Notes identifying which graphics need replacement.

Keep the original photographs at their full resolution rather than sending only screenshots or heavily compressed copies when possible.

What If Measuring the Graphics Is Too Complicated?

Some RV graphics are straightforward. Others cover large areas with multiple curves and interacting pieces.

If the design is particularly complicated, professional evaluation may be preferable to trying to document every contour yourself.

This is especially true when:

✅ Several large graphics need reproduction.

✅ Precise alignment is important.

✅ The graphics cross multiple panels.

✅ Large sections are already missing.

✅ The entire graphic package will be replaced.

The purpose of measurements is to provide reliable information, not to force the owner to reverse-engineer a complicated design alone.

Keep Your Documentation After the Project

Don’t discard the photographs and measurements after replacement graphics are produced.

Keep copies of:

• Artwork, when available
• Measurements
• Photographs
• Graphic identification notes

If one of the replacement decals is damaged years later, having those records may make another replacement significantly easier.

Frequently Asked Questions

What measurements do I need for replacement RV decals?

At minimum, record the maximum width and height. Complex graphics may also require intermediate widths, distances between design elements, and measurements showing their position relative to doors, windows, seams, or other fixed features.

Can replacement RV graphics be made from photographs?

Photographs can provide valuable reproduction references, especially when original artwork is unavailable. Their usefulness depends on image quality, camera angle, available measurements, and the complexity and condition of the graphic.

Should I remove my peeling decals before taking measurements?

No. If the existing graphics will be used as references, photograph and measure them before removal.

What if part of my RV decal has already fallen off?

Document everything that remains and look for matching or related graphics elsewhere on the RV. Older photographs may also provide useful information about missing portions.

Do I need the RV’s year and model?

Providing the year, manufacturer, and model can help identify the graphic package and distinguish between visually similar RVs, although this information alone does not guarantee that original artwork or replacement decals are available.

Should I measure curved graphics along the curve?

For complex graphics, multiple reference measurements are more useful than relying on a single overall dimension. Photographing the shape straight-on and documenting several points along the graphic can provide a clearer picture of its geometry.
