Quick answer
Choose an extendable fireguard if your fireplace has an irregular width or you may move homes; choose a fixed-size fireguard if your fireplace opening is standard and you want a permanent, streamlined fit.
Why fit flexibility matters for baby safety
A fireguard that doesn't fit snugly leaves dangerous gaps a crawling baby can reach into. Extendable models solve this by adjusting to your exact fireplace width, but they add moving parts and may look bulkier. Fixed fireguards offer a cleaner look but require precise measurement and are less forgiving if your fireplace dimensions change.
What to consider before choosing
First, measure the width of your fireplace opening at the narrowest point. If you have an uneven stone or brick surround, an extendable guard can adapt better. Second, think about storage: fixed guards are usually one piece and harder to pack away. Finally, check whether the guard includes a mesh that is too wide for small fingers—this is a safety feature regardless of type.
Trade-offs at a glance
- Extendable fireguard: Adjusts to fit multiple widths, often with a telescopic or sliding mechanism. Ideal for irregular fireplace openings or if you plan to move. Check the minimum and maximum width range before buying.
- Fixed fireguard: Available in set sizes—usually for standard 30–36 inch openings. No moving parts, so it's simpler and often more affordable. Measure your fireplace width twice; returns are harder if the size is wrong.
- Safety mesh spacing: Both types should have mesh gaps small enough to prevent fingers or objects passing through. This is a key safety feature regardless of adjustability. Look for a mesh spacing of 10 mm or less for baby safety.
