Which flag base you need comes down to two questions: is the flag going indoors or outdoors, and is there grass or soil to anchor into? Ground spikes only work in soil or grass, water and concrete bases handle wind on hard ground outdoors, and cross or metal bases are the standard choice for indoor floors, lobbies, and exhibition stands.
Here's what each base type is actually built for, so you're not guessing on a National Day order.
Indoor bases: cross base and metal base
Our Cross Base and Metal Base flags are the standard choice for indoor floors — offices, malls, hotel lobbies, and exhibition halls. A cross base sits flat and low, taking up minimal floor space, while metal bases add a bit more weight and stability for taller flag poles indoors. Neither is designed to handle real outdoor wind on its own.
Outdoor bases: water base, concrete base, and ground spike
- Water base — a hollow base filled with water for weight (commonly 20–32kg once filled), giving portable outdoor stability without the bulk of solid concrete. See our Water Base Flags.
- Concrete/plastic-coated concrete base — heavier and more permanent than a water base, better suited to consistently windy spots or longer outdoor placements.
- Ground spike — the simplest and lightest outdoor option, but only works where you can drive a spike into grass or soil — not suitable for paved areas, tiled entrances, or indoor floors. See our Ground Spike Flags.
Desk and tabletop options
For a single desk or meeting table rather than a floor display, Desk Flags and Table Top Flags use a small weighted or clip-on base sized for a flat surface rather than the floor — no need for a full-size base at this scale.
Matching base to flag type
Curved-top and teardrop flags (the tall, shaped outdoor advertising flags) are almost always paired with a water base, concrete base, or ground spike, since their height catches wind. Straight rectangular flags on a shorter pole are more commonly paired with cross or metal bases, particularly indoors. If you're ordering a flag and aren't sure which base ships with it or suits your location, our Flag Bases & Accessories collection covers replacement and add-on bases separately.
A quick decision guide
- Indoor lobby or office floor: cross base or metal base
- Outdoor entrance on paving or tile: water base or concrete base
- Outdoor on grass or soil: ground spike
- Desk or meeting table: desk flag with its own small base
Frequently Asked Questions
What's the difference between a water base and a concrete base?
A water base is a hollow base filled with water on-site for portable weight, typically 20–32kg once filled. A concrete base is solid and heavier from the start, better suited to permanent or consistently windy outdoor spots.
Can a ground spike be used indoors or on a paved area?
No — ground spikes only work driven into grass or soil. For paved, tiled, or indoor floors, use a cross base, metal base, water base, or concrete base instead.
Is a cross base heavy enough for outdoor use?
Not reliably — cross bases are designed for indoor floors. For outdoor placement, a water base, concrete base, or ground spike (where soil allows) provides the weight or anchoring needed to handle wind.
Do flag bases come with the flag, or are they sold separately?
This varies by product — some flags are sold as a complete flag-and-base set, while bases are also available separately for replacement or for pairing with a flag you already own.
What base is best for an exhibition stand?
Cross base or metal base flags are the standard choice for exhibition halls, since they're indoors and need to sit flat without taking up much floor space.
