How to Measure Your Fridge or Freezer Door Seal

​Follow these 6 simple steps to get an accurate measurement — so your new seal fits perfectly first time.

⚠ Important Disclaimer: Measure carefully — an incorrect measurement means the seal won't fit. Summit Air & Refrigeration accepts no responsibility for seals cut to measurements supplied by the customer. If in doubt, contact us before ordering — we're happy to help!

Step-by-Step Measuring Guide

1

Gather Your Tools

You'll need a flexible tape measure (cloth or plastic — not a rigid steel ruler), a pen, and paper or your phone to record measurements. A helper makes it easier for larger units.

💡 Tip: A flexible dressmaker's tape measure is ideal — it follows contours better than a metal one.

2

Open the Door Fully

Open your fridge or freezer door all the way. Locate the rubber door seal (gasket) — it's the flexible rubber strip that runs around the inside edge of the door, creating an airtight closure.

3

Measure the Width

Measure the inside width of the door opening — from the inner edge of the seal groove on one side to the inner edge on the other side. Do NOT measure the outside of the door.

💡 Write this measurement as: Width = [your measurement] mm

4

Measure the Height

Measure the inside height of the door opening — from the inner top edge of the seal groove down to the inner bottom edge. Again, measure the inside opening, not the full door height.

💡 For top-mount freezers: measure the fridge door and freezer compartment door separately.

5

Find Brand & Model Number

Check inside the fridge on the wall panel, or along the door frame edge, for a label showing the brand name and model number. This helps us confirm the correct seal for your unit without needing custom measurements.

💡 Common locations: left-side interior wall, top of fridge interior, or inside the door hinge area.

✓ We stock pre-made seals for Fisher & Paykel, Westinghouse, Samsung, LG, Kelvinator & Electrolux.

6

Take Photos (Highly Recommended)

Photograph your fridge/freezer with the door open, and take a close-up of the existing door seal. A photo of the seal profile cross-section (if damaged or partially removed) is especially helpful for custom orders.

You can upload photos directly on our product page when placing a custom order — this helps us ensure the perfect fit.

💡 For commercial units (Skope, Bromic, True, Turbo Air): also photograph any branding/model number on the unit.

Pro Measuring Tips

📏 Measure Twice

Always measure twice and record both readings before placing your order.

🌡️ Measure at Room Temp

Rubber seals can shrink slightly when cold — measure when the unit is at room temperature for the most accurate reading.

📐 Inside, Not Outside

Always measure the inside of the opening (groove), never the outside dimensions of the door itself.

↕️ Check All Four Sides

On some models, the top/bottom differ from the left/right. Measure all four sides to be safe.

🔧 Old Seal Can Help

Lay your old seal flat and photograph it next to a ruler — this helps identify the profile type for replacement.

💬 When in Doubt, Ask

Our team is happy to help you identify the correct seal before you order. No charge for advice!
