Vase Measurements: How to Choose the Right Size for a Bouquet
Vase measurements usually mean the overall height, opening diameter and widest body diameter; usable internal depth matters too. Measure height from the surface beneath the vase to its rim, and measure the opening across its inside edges. To choose a vase for flowers, check these dimensions against the trimmed stems and the space their bundle needs at the neck.
Customers at Pyat Tsvetov (5 Flowers) often bring a photograph of a vase when choosing flowers for someone else. A photograph helps with shape, but a ruler gives more useful information about fit. From our experience running Saint Petersburg flower shops since 2011, the best starting point is a few clear measurements and an understanding of how the bouquet will sit in water.
Measure the parts that affect how flowers sit
Place the empty vase on a level surface and measure vertically from the tabletop to the highest point of the rim. This is its overall height, which is usually the figure given in a product listing. For an uneven or sloping rim, record both the lowest and highest points so you know where stems can rest.
Next, measure the opening from one inside edge to the opposite inside edge, passing through the centre. Thick glass can make the outside diameter noticeably larger than the space available for stems. For an oval or rectangular opening, record both length and width; for a narrow-necked vase, also note any tighter point below the rim.
Measure the widest part of the body and the width of the base separately. The body tells you how much room stems have below the neck, while the base helps you judge whether the vase will sit comfortably on a shelf or table. Write dimensions with labels, such as height 25 cm, opening 10 cm and body width 16 cm, rather than leaving their order unclear.
Check internal depth, units and water capacity
Overall height and usable depth are different measurements, especially in glass vases with a thick base. Lower a ruler gently inside an empty vase to measure from the inner bottom to the rim. Avoid forcing it into a curved base or narrow neck, and use a non-scratching measuring tool if the finish is delicate.
Keep all your measurements in one unit before comparing vases or discussing a bouquet. One inch equals 2.54 cm, so a vase listed as 10 inches tall is 25.4 cm tall. Round sensibly for flower arranging: knowing that a vase is about 25 cm high is normally more useful than retaining several decimal places.
Capacity describes how much water a vessel holds, but it does not tell you whether a bouquet will fit through the opening. If capacity is unknown, use a measuring jug to fill a watertight vase to a practical level and record the amount added. Leave room for stems to displace water; the volume up to the brim is not a useful daily filling target.

Match vase height to the stems you will actually use
Measure stems after deciding how much you need to trim, rather than choosing a vase from the bouquet's wrapped height. Packaging and foliage can make a bouquet look taller or wider than its usable stems. Hold the flowers beside the vase before cutting, with their cut ends aligned near the level of the inner bottom.
As a visual starting point, the complete arrangement can stand around one and a half to twice the height of the vase, including the vase itself. This is an arranging guideline, not a flower-care requirement or a fixed rule. Heavy flower heads, curved stems and a loose branching shape may need a different balance and more support.
The rim should support the stems without pressing into flower heads or trapping leaves in water. If the vase hides most of the flowers, try a shorter vessel before making a large cut. If long stems lean sharply over the edge, a taller vase may suit them better; our guide to what holds up flowers explains how stems and vessels work together.
Choose the opening for the bouquet's stem bundle
The opening often matters more than the widest part of the vase. A broad body with a narrow neck may hold plenty of water yet still squeeze a dense bunch of stems. Check that the bundle enters easily, without forcing stems against the glass or crushing softer growth between firmer stems.
An opening that is too wide lets a small bouquet spread until its centre looks empty. A narrower neck can gather the stems, while a wider opening suits a loose arrangement with room between flowers. There is no dependable conversion from flower count to opening diameter because stem thickness, foliage and branching vary considerably.
Try the bouquet in the empty vase briefly while supporting it with your hand, then remove it before preparing the water. Look for pinched stems, heads pressed together and a bundle that pulls the vase off balance. If the fit is poor, choose another vessel or divide the flowers between suitable vases; vase shape for your bouquet covers the effect of different profiles.
Allow for placement, stability and daily care
Measure the space where the arrangement will stand as well as the vase itself. A vase may fit a shelf while the flowers brush the shelf above or extend into a walkway. On a dining table, check the finished arrangement from a seated position so that flower heads do not block conversation across the table.
Test stability with water in the vase and the flowers arranged, keeping a hand nearby while checking. A narrow base and a broad, heavy bouquet can be an awkward combination even when the height looks attractive. Keep the arrangement away from table edges, and allow space to lift the vase safely for cleaning and water changes.
Remove leaves that would sit below the waterline, use a clean vessel and check the water level daily. The right depth depends on the flowers and their condition, so vase height alone cannot set a universal filling level. Keep cut ends in water and follow any care instructions supplied; our practical vase-life guide explains other factors that affect how long flowers last.
Use vase measurements when sending flowers to Russia
When choosing from our bouquets catalogue, use the recipient's vase dimensions as a practical reference. Record the height, inside opening width and usable depth, and ask whether the recipient has a suitable vessel if you can do so without spoiling the surprise. For questions, call 8 (812) 507-67-05; measurements help make the discussion more precise than a description such as 'a large vase'.
We deliver flowers across Russia, with city delivery costing 500 RUB; the operator confirms the price for remote districts and suburbs when confirming the order. In large cities, express delivery is available in 1–2 hours after order confirmation, alongside an exact-time option within ±30 minutes and windows of 09–12, 12–15, 15–18 or 18–21. Orders can be placed 1–30 days ahead, and delivery in Saint Petersburg is available around the clock.
Delivery is anonymous by default: the courier does not name the sender, and a card with your text is free. The courier calls the recipient about 15 minutes before arrival, so choose a time when they are likely to be available. Online checkout uses CloudPayments; check the payment options displayed there rather than assuming a particular foreign card will work, and see delivery and payment for the ordering information.
Frequently asked questions
What do vase measurements usually include?
They usually include overall height, opening diameter and maximum body width, although listings may use a different order. Check the labels and measure usable internal depth separately if the vase has a thick base.
Should I measure the inside or outside of a vase opening?
Measure between the inside edges to find the space available for stems. For an oval or rectangular opening, record both dimensions rather than a single diameter.
How tall should flowers be compared with the vase?
A common visual starting point is a complete arrangement around one and a half to twice the vase's height, measured from the tabletop to the highest flower. Adjust this for stem strength, flower weight and stability, checking the flowers beside the vase before trimming.
Can I choose a vase just from its capacity in litres?
Capacity helps you understand water volume, but it does not show whether the stem bundle will fit. Compare the opening, usable depth and base width as well.
What if the recipient is out when flowers arrive?
If the recipient is absent, we agree a second delivery the same day or handing the flowers to a neighbour or concierge with the sender's consent. The courier calls about 15 minutes before arrival to help coordinate the delivery.
