Shower Door Sweep for a 5/8 Inch Gap
Quick answer
A 5/8 inch gap is at the top of what a common 3/4 inch wipe can seal — it works, but with almost no flex margin. A 1 inch "extra tall" wipe is the safer buy, and fewer products offer it, so check the wipe height in the listing, not just the glass size. First rule out door sag: 5/8 inch gaps are frequently 3/8 inch installs that drifted.
5/8″ gap = 5/8″ · 0.625 in · 15.9 mm
Data reviewed:
What to measure before buying
- Glass thickness at the bare edge — pull back a section of the old seal first (1/4″, 5/16″, 3/8″, or 1/2″)
- Bottom gap from glass edge to threshold at the HINGE end, door closed
- Bottom gap at the HANDLE end, door closed — note any difference
- Door width along the bottom edge (for trimming the new seal)
- Where the water actually exits: under the door, off a bottom corner, or down a vertical edge
- Photo of the old seal's cross-section before removing it
- Gap with the door fully closed and latched — open-position readings run large on pivot doors
- Difference between hinge-end and handle-end gaps (over 1/8″ means adjust the hinges first)
Wipe height vs. gap size
| Measured gap | Recommended wipe | Note |
|---|---|---|
| 1/8–3/8″ | 1/2″ wipe | The standard sweep size on frameless doors |
| 3/8–5/8″ | 3/4″ wipe | Pick this when the gap varies end to end |
| 5/8–7/8″ | 1″ wipe | Sold as "extra tall" — check the listing states wipe height |
| 7/8–1 1/8″ | 1 1/4″ wipe | Last resort; fix door height or add a threshold first |

Common buying mistakes
- Trusting a "universal" sweep listing without a stated wipe height — many top out at 3/4″.
- Sealing a sagging door: adjust hinges first, then re-measure; you may be back in 3/8″ territory.
- Stacking two thin sweeps; doubled channels sit crooked and leak between layers.
Frequently asked questions
Will a standard sweep seal a 5/8 inch gap?
A 3/4 inch wipe technically reaches, but with only 1/8 inch of flex it loses contact on uneven thresholds. A 1 inch wipe is the reliable choice at this gap.
Why is my gap 5/8 inch when the door is only a few years old?
Hinge creep. Glass doors sag as pivot screws settle; re-squaring the door usually recovers 1/8–1/4 inch of gap and lets a normal 3/4 inch wipe work.
Are extra-tall wipes noisy or draggy?
A properly sized 1 inch wipe over a 5/8 inch gap flexes about 3/8 inch — noticeable but normal. Drag becomes a problem only when overlap exceeds roughly 1/2 inch.
