Most altar candlestick mistakes are size mistakes. A candlestick that is too short disappears behind the altar; one that is too tall hides the crucifix. A socket that is too wide lets the candle wobble; one that is too narrow will not accept the candle at all. This guide gives the measurements that matter and the ranges that work in practice.
The Three Measurements That Matter
- Height — from the base to the top of the socket or pricket.
- Socket diameter — the inside diameter of the cup, or the length of the pricket spike.
- Base diameter — the footprint that keeps the candlestick stable.
Write these three numbers down before you order candles or candlesticks. They are more useful than a photograph.
Height: What Works Where
| Height | Setting | Notes |
|---|---|---|
| 4–15 cm | Side altars, home altars, Advent wreaths, slim candles | Small range; pairs and singles |
| 16–30 cm | Parish altars, chapels, pairs and sets | The working size for most churches |
| 31–55 cm | Cathedrals, high altars, solemn Mass | Usually solid brass; 2–4 kg |
On a parish altar, 15–30 cm is the common range. The candlesticks should be tall enough to be seen from the nave but not so tall that they obscure the cross. Pairs must be exactly equal in height.
Socket Sizes and Candle Diameters
| Socket | Approximate candle diameter | Typical use |
|---|---|---|
| 7/8 inch | 2.2 cm | Taper and devotional candles |
| 1½ inch | 3.8 cm | Parish altar candles |
| 2 inch | 5 cm | Larger altar candles |
| 3 inch | 7.6 cm | Cathedral and large altar candles |
| 4 cm | 4 cm | Specific models with a 4 cm socket |
| Pricket | Varies | Taper candles pressed onto a spike |
Measure the inside of the socket, not the outside. A candle should sit upright with a little clearance; it should not drop in loosely or need to be forced. If the candle is slightly narrow, a candle follower or a socket insert can take up the slack.
Base Diameter and Stability
A tall candlestick needs a wide base. As a rule of thumb, the base diameter should be at least one third of the height for a freestanding candlestick, and more for a piece that will be moved often. A weighted base is better than a light one. If the candlestick rocks on a level surface, the base is warped or the piece is damaged.
How to Measure a Candlestick
- Place the candlestick on a level table.
- Measure from the table to the top of the socket or the tip of the pricket.
- Measure the inside diameter of the socket across its widest point.
- Measure the base diameter.
- Check the weight if the piece is tall; a light tall candlestick is a risk.
Matching Candlesticks to the Altar
The candlesticks should be in proportion to the altar and the crucifix. A small side altar needs small candlesticks; a high altar needs large ones. The number of candles also affects the arrangement: two candles on a small altar, four or six on a parish altar. If you are buying a set, order all the pieces at the same time so that the height and finish match.
Frequently Asked Questions
Q: What is a 5-inch altar candlestick in centimetres?
A: Five inches is about 12.7 cm. In our collection, the closest sizes are the 12 cm brass holders and the 15 cm altar candlesticks. Check the socket size as well as the height.
Q: How do I measure a candlestick socket?
A: Measure the inside diameter of the socket across its widest point. Compare it with the diameter of the candle you intend to use. If the candle is slightly narrow, use a candle follower or a socket insert.
Q: What size candle fits a 7/8-inch socket?
A: A 7/8-inch socket takes a candle of about 2.2 cm diameter. This is a common size for taper and devotional candles. Measure the candle before ordering.
Q: How tall should altar candlesticks be?
A: On a parish altar, 15–30 cm is the common working size; on a high altar or cathedral, 30–55 cm. The candlesticks should be in proportion to the altar and the crucifix, and pairs must be equal in height.
Q: Can I use a candle that is slightly smaller than the socket?
A: Yes, with a candle follower or a socket insert to take up the slack. Without one, the candle may wobble and drip wax. A candle that is too large for the socket should not be forced.
Q: How wide should the base of a tall candlestick be?
A: As a rule of thumb, at least one third of the height, and more for a piece that will be moved. A weighted base is better than a light one. If the candlestick rocks, do not use it.
