Sandwich Board Frame Size vs Insert Size: The Measurement That Prevents Ordering Mistakes

When ordering a replacement sandwich board sign, measure the removable printed panel, not the outside of the A-frame. Frame size describes the stand. Insert size describes the panel that must fit inside it. Those measurements are not interchangeable.

If your existing panel measures 24 inches wide by 36 inches tall, order by those panel dimensions only after checking how the frame holds it and whether it accepts the new panel’s thickness. A stand described as a 24 x 36 sandwich board may be labeled by its intended insert size, but the label alone does not confirm what fits your particular frame. At Legit Fast Printing, our practical rule is simple: measure the panel, check the opening, then verify the holding method before submitting artwork.

This matters whether you need a storefront promotion, event direction sign, or a new message for an existing stand. A panel that is too large may not install. One that is too small may sit loosely or leave a visible gap. A correctly sized panel can still fail to fit if the frame’s channels do not accept its material.

Frame size, insert size, and visible area are different measurements

A sandwich board, often called an A-frame sign, supports a message on one or both sides. For a stand with removable printed panels, there are three separate dimensions worth recording:

• Overall frame size: The outside width and height of the stand. Use these measurements when checking storage space and where the stand will be placed.
• Insert size: The full width and height of the removable printed panel, measured from edge to edge. Use these dimensions when ordering a replacement panel.
• Visible area: The portion of the panel people can see once it is installed. Rails, channels, clips, or trim may cover part of its edges.

A fourth measurement matters for placement: the open footprint. That is the floor or sidewalk space the unfolded stand occupies. A panel measurement does not tell you how far the legs spread.

Think of a 24 x 36 panel as a description of the printed piece, not a measurement of the complete standing sign. The frame needs room to support that piece, and its outside dimensions depend on its design. The visible message area may be smaller than the panel because some of the panel can sit behind retaining edges.

These distinctions prevent two different ordering mistakes. Using the stand’s outside dimensions can produce an oversized insert. Designing every important word right against the panel edge can leave those words hidden after installation.

How to measure an existing sandwich board for a new insert

1. Start with the old panel if you have it

Remove the existing panel and place it on a flat surface. Measure its full width from one outer edge to the other, then its full height. Write down the result as width x height, and state whether the panel stands upright or sits horizontally.

Do not measure only the portion visible through the frame. A rail or channel can hide an edge, so a measurement taken while the sign is installed may be smaller than the actual panel. If the old panel has been cut, bent, or forced into place, treat it as a clue rather than proof of the correct size.

2. Check the space that holds the panel

Look at the frame with the insert removed. Identify where the panel’s edges sit and how it enters the stand. Does it slide behind rails, drop into slots, or attach with clips? Record the usable space and check the width and height in more than one spot if the frame looks bent or worn.

Do not assume that the visible opening equals the required insert size. A sliding panel may extend behind the edges of the opening. A panel held by clips may sit differently. If you are unsure which dimension the frame maker uses, check any available frame instructions or compare the opening with an insert that has fitted correctly.

3. Check thickness and rigidity

Width and height are not the whole fit test. Measure the old panel’s thickness or check the frame specifications. A channel that accepts a thin sheet may not accept a rigid board of a different thickness. Likewise, a panel can have the right outside dimensions but fail to sit securely in the holding system.

The custom 24 x 36 A-frame insert listed by Legit Fast Printing is printed on 4 mm rigid coroplast. Confirm that your stand accepts that material and thickness before ordering. The listing is for the one-sided insert only, not a sandwich board frame or hardware.

4. Check portrait orientation and edge coverage

A panel that is 24 inches wide and 36 inches tall is portrait. A panel that is 36 inches wide and 24 inches tall is landscape. They use the same numbers in a different direction and require different artwork layouts. Tell the printer which dimension is the width.

With the old panel installed, note where the frame covers the design. Keep your headline, logo, contact details, and other essential information away from those covered areas on the replacement artwork. If your frame has wide rails, a small edge allowance that worked in another stand may not work in yours.

5. Record the answer before ordering multiple copies

Write one short specification you can use when ordering and reordering: panel width, panel height, orientation, thickness, material, and how the panel attaches. If several stands will receive the same insert, measure each stand or confirm that they share the same frame model and fit. Similar-looking A-frames do not necessarily accept identical boards.

When dimensions are uncertain, a photo of the empty frame, its retaining edges, and the old panel can help explain the problem to a printer. Do not place an order based solely on an approximate outside-frame measurement.

What a 24 x 36 label does and does not tell you

Suppose your old printed panel measures 24 inches wide by 36 inches tall. That is useful evidence that a 24 x 36 replacement may be appropriate. It does not, by itself, settle every question. You still need to check whether the proposed panel’s thickness fits and whether the old panel was held in place securely.

Now suppose the outside of the stand measures roughly 24 inches across. That number alone does not establish a 24-inch insert width. The sides of the frame take up space, and the holding system determines how the panel sits. Measure the removable board or consult the frame specifications instead of matching the stand’s exterior width to a product name.

The same care applies to height. The complete A-frame includes parts that are not the printed panel. Ordering an insert using the stand’s full standing height can produce a piece that is too tall.

If you are deciding whether to keep your existing stand, see our guide to replacing A-frame inserts instead of buying another stand. Reusing a sound frame makes sense when you can establish the insert fit and only the message needs to change.

Choose the sign format for the location, not just the artwork

Some frames are made to hold a 24 x 36 insert, but that does not make 24 x 36 the right size for every location. If you already own a frame, its required insert dimensions are the starting point. If you are choosing a new display setup, start with where people will see it and how much room the stand can safely occupy.

• Storefront or entry sidewalk: Choose a stand that fits the permitted space and puts the message in the path of approaching customers without blocking their route.
• Event check-in or parking direction: Plan a short message with a clear arrow or instruction. Pick a display location where visitors can act on the sign before reaching a turn or entrance.
• Lawn or roadside placement: A staked custom yard sign may be a better fit than a standing sandwich board when the display belongs in soil. The two formats use different supports, so do not assume a yard sign panel will fit an A-frame.

For a new stand, check both the insert specification and the open footprint before buying. The first determines which printed panel to order. The second tells you whether the deployed stand suits the space.

If you need outdoor printed signage at several decision points, match the format to each spot. A sandwich board can carry a changeable entrance message, while custom yard signs can mark routes across grassy areas. Count the places that require instructions, then order enough signs or inserts for those locations rather than choosing a quantity from the number of attendees alone.

Material and printing checks before you purchase

Corrugated plastic is useful for many temporary outdoor signs because it is lightweight and weather-resistant. Legit Fast Printing’s A-frame product uses 4 mm rigid coroplast, but material choice still has to match the frame. Inspect channels, clips, and any old panel before assuming a particular board will work.

Also check what the product includes. An insert-only listing supplies the printed panel, not a stand. If your frame is broken or missing, a replacement panel will not solve the display problem. If you already have a sound frame, buying only the insert avoids ordering another stand unnecessarily.

The listed Legit Fast Printing insert is one-sided. If both faces of your sandwich board need a message and the frame takes two separate panels, plan for the required number of inserts and check the listing’s available pack options before checkout. Do not assume one printed panel supplies both sides or that the same artwork belongs on each face.

For a sidewalk promotion, the side facing customers approaching from one direction may need a different message from the opposite side. Plan the wording for each position, then confirm the printing options available for the product you choose. For more on material care, read sandwich board insert materials for outdoor use.

Design the artwork for the part people can actually see

A correctly sized panel can still make a poor sign if the frame hides its most important information. Before preparing the final file, put an existing insert in the stand and check which edges disappear behind the retaining parts. Use that observation to keep key text inside the visible area.

• Lead with the action: Use wording such as “Check In Here,” “Open House Today,” or “Sale Inside” when that is what visitors need to know.
• Make one message dominant: A short headline is easier to find than several competing offers.
• Use readable contrast: Check the design at a distance similar to where customers will first encounter the stand.
• Protect essential details: Keep dates, arrows, phone numbers, and web addresses clear of rails and channels.
• Review the final file: Confirm spelling, current prices, dates, directions, and orientation before placing the order.

Legit Fast Printing asks customers ordering its A-frame insert to upload high-resolution artwork and check spelling. If you need help with a custom sign design, its design help information explains how to request assistance after ordering. Design help can address the artwork, but it is still important to establish the physical panel dimensions before you buy.

Placement and quantity: two checks that prevent a second order

Before selecting a pack quantity, walk the route your customers or guests will take. Identify each spot where a message is needed and which direction people approach from. This shows whether one stand is enough, whether both sides need inserts, and whether another form of printed signage is needed farther along the route.

For example, imagine a school event using a sandwich board at the entrance and yard signs along an outdoor path. The entrance stand may need a welcome message on each side if people approach from both directions. The path signs need their own placement and count. Ordering only one insert for the entrance, without checking how many panels the stand holds, could leave one face blank.

Place a sandwich board so the message faces approaching traffic and the stand does not block a doorway, ramp, or walking route. Check local rules before placing it on a public sidewalk. Check its full open footprint in the actual location, because an insert’s width does not describe the space taken by the stand’s legs.

If a promotion changes regularly, keep a record of the confirmed insert dimensions and artwork for future orders. That makes it easier to replace the message without remeasuring from memory or accidentally ordering a yard sign in the same nominal size.

Best practices for an error-free insert order

• Measure the removed panel edge to edge when an old insert is available.
• Verify the frame opening and holding method, particularly if the old panel was loose or difficult to install.
• Confirm the new panel’s thickness and material against the stand’s requirements.
• Write dimensions as width x height and state portrait or landscape.
• Check the visible area before positioning essential artwork.
• Count the frame faces that need printed panels, then select a suitable quantity.
• Confirm whether the listing includes an insert, a stand, hardware, or some combination.
• Keep a copy of the measurements for future replacement inserts.

If your frame has no usable old panel and you cannot confirm its insert specification, pause before ordering. An outside measurement or a familiar size label is not a reliable substitute for a known fit.

Frequently asked questions

Is frame size the same as insert size?

No. Frame size describes the stand’s outside dimensions. Insert size describes the removable panel that goes into it. Use the panel size to order a replacement insert and the stand’s dimensions to plan its placement.

Can I order from a label that says 24 x 36 A-frame?

Use the label as a starting point, not your only fit check. Confirm the old panel’s dimensions or the frame’s insert specification, and check that the stand accepts the proposed panel’s thickness and material.

What should I measure if the old insert is missing?

Examine the area where the panel sits, measure the available space, and note how the frame retains it. Check the frame manufacturer’s specifications if available. If the required cut size is still unclear, do not assume the outside frame measurement is the insert size.

Why does my correctly sized artwork look cropped in the frame?

The frame may cover the edges of the installed panel. Artwork dimensions describe the whole printed board, while the visible area can be smaller. Move important text and graphics inward based on the coverage you observe on your stand.

Does a 24 x 36 A-frame insert come with a stand?

The Legit Fast Printing product described here is an insert only. Its listing says the sandwich board frame and hardware are not included. Confirm what is included on any sign product page before purchasing.

What if I need a sign for a lawn instead of a sidewalk?

Choose a display made for that location. Custom yard signs are intended for lawn placement with compatible supports, while sandwich board inserts require an appropriate A-frame. A matching width and height do not make the two display systems interchangeable.

How many inserts should I order for a two-sided stand?

Check whether your stand holds separate panels on each face and decide whether both faces need a message. The Legit Fast Printing insert listing specifies one-sided printing, so review the number of printed panels needed and the available pack quantity before ordering.

Can an insert be the right width and height but still not fit?

Yes. Thickness and the way the frame holds the panel also matter. Compare the proposed material with the old insert and inspect channels, clips, or other retaining parts before purchasing.

Measure once, then order with confidence

The measurement that prevents most sandwich board insert mistakes is the full edge-to-edge size of the panel that fits your stand. Confirm it against the frame’s opening and holding method, check material thickness, and design for the area that remains visible after installation. Then count the printed faces you need.

If your stand accepts a 24 x 36-inch, 4 mm rigid coroplast panel, review the custom one-sided A-frame insert from Legit Fast Printing and compare its listed details with your frame before placing the order.
