Three formats cover a fence or wall, and they are not interchangeable. Hedge panels cover 11 square feet each at roughly $5.90 to $7.75 per square foot. Ivy rolls cover 33 square feet each and land under $2.00 per square foot, around a third of the cost. Portable hedges cost the most per unit and fix to nothing at all. The right choice is decided by what you are allowed to attach to, not by preference.
The cost comparison, stated plainly
Per square foot, rolls are roughly three times cheaper than panels. That single fact reshapes most fence budgets, and it is the number worth checking before committing to a format. A roll covers exactly three panels' worth of wall, because 33 square feet divided by 11 is three.
Panels are not overpriced by comparison. They are a different product: rigid backing, interlocking edges that conceal joins, and denser foliage that holds shape when cut to fit around posts and meter boxes. You are paying for finish and for the join quality on a wall people stand close to.
Choose by what you can fix to
Solid fence, wall or render: hedge panels. The backing grid spreads load across the whole panel rather than a few points, which is why fixed panels are the longest-serving outdoor format.
Chain-link, mesh or balustrade: ivy rolls. The mesh backing ties straight through the existing structure with no drilling, covers ground fast, and the shade-cloth-backed version blocks sightlines rather than just softening them. Tie density matters more here than on rigid panels, because the backing carries everything.
Nothing you may attach to at all: portable hedges. Rentals, balconies, roof terraces, restaurant terraces, event spaces. These are freestanding units on steel frames, roughly 10.5" deep, and they stand where you place them. Per unit they are the most expensive option, but they need no fixings, leave no trace, move for events and come with you when you move out.
Where each one fails
Panels fail at the fixings, not in the foliage. Under-tying is the single most common cause: a panel held at four corners flexes with every gust and tears at a fixing hole. Rolls fail when the backing mesh is under-tied for the same reason. Portable hedges fail by going over in wind, which is a ballast problem, not a product problem. Weight the planter. The detail on exposed sites is in do artificial hedges hold up in wind.
Mixing formats on one job
Most real installs use more than one. Panels on the solid boundary, rolls over the gate and mesh sections, a portable hedge closing the gap where a driveway prevents anything being fixed. Matching the foliage style across formats matters more than matching the format itself, since the eye reads leaf colour long before it reads construction.
Before ordering
Work out the area first using the panel quantity guide, then check colour against your actual fence with a sample panel. Fixings should go in the same order so everything arrives together, from the install parts range.
