Moisture can be a problem for cameras, lenses and other photographic equipment, especially when they are stored for long periods or used in humid conditions.

Silica gel packets are a simple way to help reduce moisture inside a camera case, but how much should you use?

What Size Silica Gel Packet Should I Use?

As a practical starting guide:

• Small camera or lens case: 1 × 5g silica gel packet
• Medium camera case: 1 × 10g packet or 2 × 5g packets
• Large hard camera case: 1 × 25g packet
• Large equipment case: 1 × 50g packet or 2 × 25g packets

These amounts are a general guide only. The amount required can vary depending on the size of the case, how well it is sealed, the surrounding humidity and how often the case is opened.

For a small camera case, our 5g Tyvek silica gel packets are a convenient option for everyday moisture protection.

For larger camera and lens cases, consider using a 10g or 25g silica gel packet for additional moisture capacity.

Where Should You Put Silica Gel?

Place the silica gel packet inside the camera case where air can circulate around it.

For larger cases, you can place two smaller packets in different sections—for example, one near the camera body and another near the lenses.

Keep the silica gel packet sealed and intact. Do not cut the packet open or allow loose silica gel beads to come into contact with camera components.

Why Use Silica Gel for Camera Storage?

Humidity and condensation can contribute to problems such as:

• Lens fungus
• Corrosion
• Fogging and condensation
• Moisture damage to electronic components

Major camera manufacturers including Sony and Canon recommend keeping camera equipment in a cool, dry environment. Sony Australia also recommends silica gel packets as one option for helping keep stored lenses dry.

Silica gel works best when used inside a reasonably well-sealed camera case or storage box.

Don't Store Wet Camera Equipment

Silica gel is designed to help control moisture in the air—it should not be used as a replacement for properly drying wet camera equipment.

If your camera or lenses have been exposed to rain or heavy moisture, allow them to dry before placing them into a closed storage case.

How Often Should Silica Gel Be Replaced?

There is no fixed replacement period.

Silica gel in a tightly sealed case may remain effective much longer than silica gel in a soft camera bag that is opened regularly.

If you want an easy way to see when your silica gel needs attention, indicating silica gel can be useful because it changes colour as it absorbs moisture.

Which Silica Gel Should I Choose?

For most camera storage applications:

Small case: 5g silica gel packet
Medium case: 10g silica gel packet
Large case: 25g silica gel packet

For larger storage boxes and equipment cases, consider 50g packets.

Choosing the right size helps protect your valuable camera and lens equipment without filling your case with unnecessary packets.
